Power-on 5.7.7 Selecting a desired motor drive control The FRENIC-HVAC supports the following motor drive control.  V/f control with slip compensation inactive Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified by function codes.
Page 301: Function Code Basic Settings < 1
5.7 Alarm Mode  Dynamic torque vector control To get the maximal torque out of a motor, this control calculates the motor torque for the load applied and uses it to optimize the voltage and current vector output. Selecting this control automatically enables the auto torque boost and slip compensation function. This control is effective for improving the system response to external disturbances such as load fluctuations, and the motor speed control accuracy.
Page 302 When accessing the function code P02, take into account that changing the P02* data automatically updates the data of the function codes P03, P06 to P08, P10, P12, and H46. The motor rating should be specified properly when performing auto-torque boost, torque calculation monitoring, auto energy saving, torque limiting, automatic deceleration (anti-regenerative control), auto search for idling motor speed, or slip compensation.

Page 304  Tuning procedure (1) Selection of tuning type Check the situation of the machinery and select "Tuning with the motor stopped (P04 = 1)" or "Tuning with the motor running (P04 = 2)." For the latter tuning, adjust the acceleration and deceleration times (F07 and F08) and specify the rotation direction that matches the actual rotation direction of the machinery.
Page 305 5.7 Alarm Mode  Tuning errors Improper tuning would negatively affect the operation performance and, in the worst case, could even cause hunting or deteriorate precision. Therefore, if the inverter finds any abnormality in the tuning results or any error in the tuning process, it displays Er7 and discards the tuning data. Listed below are possible causes that trigger tuning errors.

6.3 Details of Function Codes 6.3 Details of Function Codes This section provides the details of the function codes. The descriptions are, in principle, arranged in the order of function code groups and in numerical order. However, highly relevant function codes are collectively described where one of them first appears.

Page 353 6.3 Details of Function Codes • When you start accessing the reference frequency or any other parameter with the key, the least significant digit on the display blinks, indicating that the cursor lies in the least significant digit. Holding down the key changes data in the least significant digit and generates a carry, while the cursor remains in the least significant digit.
Page 354 Switching between frequency command 1 (F01) and 2 (C30) Frequency command 1 (F01) and 2 (C30) can be switched by the external input signal Hz2/Hz1 ("Select frequency command 2/1") assigned to any digital input terminal.  For details about Hz2/Hz1, refer to the description of E01 through E07 (data = 11). Digital input signal Hz2/Hz1 Frequency command source Frequency command 1 (F01)
Page 355 6.3 Details of Function Codes Gain and bias  Input Frequency command 1 (F01) Frequency command 2 (C30) terminal [12] [C1] [V12] If F01 = 3 (the sum of [12] + [C1] is enabled), the bias and gain are independently applied to each of the voltage and current inputs given to terminals [12] and [C1], and the sum of the two values is applied as the reference frequency.
Page 356 In the case of unipolar input (terminal [12] with C35 = 1, terminal [C1], terminal [V2] with C45 = 1) As shown in the graphs above, the relationship between the analog input and the reference frequency specified by frequency command 1 (F01) is determined by points "A" and "B." Point "A"...
Page 357 6.3 Details of Function Codes (Point B) Frequency command 1 (F01), Frequency command 2 (C30) To specify the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to 100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale of terminal [12]), set the gain base point to 50% (C34 = 50).
Page 358 [ 3 ] Using digital input signals UP/DOWN (F01 = 7) When UP/DOWN control is selected for frequency setting, turning the terminal command UP or DOWN ON causes the output frequency to increase or decrease, respectively, within the range from 0 Hz to the maximum frequency as listed below. To enable UP/DOWN control for frequency setting, it is necessary to set F01 data to "7"...

Page 360 Maximum Frequency 1 F03 specifies the maximum frequency to limit the output frequency. Specifying the maximum frequency exceeding the rating of the equipment driven by the inverter may cause damage or a dangerous situation. Make sure that the maximum frequency setting matches the equipment rating.

Page 364 S-curve acceleration/deceleration To reduce an impact that acceleration/deceleration would make on the machine, the inverter gradually accelerates or decelerates the motor in both the starting and ending zones of acceleration or deceleration. Two types of S-curve acceleration/deceleration rates are available; applying 5% (weak) and 10% (strong) of the maximum frequency to all of the four inflection zones.
Page 365 6.3 Details of Function Codes Curvilinear acceleration/deceleration Acceleration/deceleration is linear below the base frequency (constant torque) but it slows down above the base frequency to maintain a certain level of load factor (constant output). This acceleration/deceleration pattern allows the motor to accelerate or decelerate with its maximum performance.

Page 369 6.3 Details of Function Codes Restart Mode after Momentary Power Failure (Mode selection) H13 (Restart time) H14 (Frequency fall rate) H15 (Continuous running level) H16 (Allowable momentary power failure time) H92 and H93 (Continuity of Running, P and I) F14 specifies the action to be taken by the inverter such as trip and restart in the event of a momentary power failure.
Page 370 Restart mode after momentary power failure (Basic operation: Auto search disabled)  The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below the undervoltage level, while the inverter is running. If the load of the motor is light and the duration of the momentary power failure is extremely short, the voltage drop may not be great enough for a momentary power failure to be recognized, and the motor may continue to run uninterrupted.
Page 371 6.3 Details of Function Codes • When the power is restored, the inverter will wait 2 seconds for input of a run command. However, if the allowable momentary power failure time (H16) has elapsed after the power failure was recognized, the inverter will no longer wait 2 seconds for input of a run command and start operation in the normal starting sequence.
Page 372 Restart mode after momentary power failure (Basic operation: Auto search enabled)  Auto search for idling motor speed will become unsuccessful if it is done while the motor retains residual voltage. It is, therefore, necessary to leave the motor for the time (auto search delay time) enough to discharge the residual voltage.
Page 373 6.3 Details of Function Codes Restart mode after momentary power failure (Allowable momentary power failure  time) (H16) H16 specifies the maximum allowable duration (0.0 to 30.0 seconds) from an occurrence of a momentary power failure (undervoltage) until the restart of the inverter. Specify the coast-to-stop time during which the machine system and facility can be tolerated.
Page 374 Restart mode after momentary power failure (Restart time) (H13)  H13 specifies the time period from an occurrence of a momentary power failure until the restart of the inverter. (When auto search is enabled, H46 (Auto search delay time 2) applies.) If the inverter starts the motor while motor’s residual voltage is still in a high level, a high inrush current may flow or an overvoltage alarm may occur due to an occurrence of temporary regeneration.
Page 375 6.3 Details of Function Codes Restart after momentary power failure (Continuous running level) (H15)  Continuity of running (P and I) (H92, H93) • Continue to run (F14 = 3) If a momentary power failure occurs when F14 is set to "3" (Continue to run), the inverter enters the control sequence of the continuous running when the DC link bus voltage drops below the continuous running level specified by H15.
Page 376 F15, F16 Frequency Limiter (High and Low) H63 (Low Limiter, Mode selection) Frequency Limiter (High and Low) (F15, F16)  F15 and F16 specify the upper and lower limits of the output frequency or reference frequency, respectively. The object to which the limit is applied differs depending on the control system.
Page 377 6.3 Details of Function Codes Bias (Frequency command 1) Refer to F01. Refer to the description of F01. F20 to F22 DC Braking 1 (Braking starting frequency, Braking level and Braking time) DC Braking (Braking response mode) These function codes specify the DC braking that prevents motor 1 from running by inertia during decelerate-to-stop operation.
Page 378 It is also possible to use an external digital input signal as the terminal command DCBRK ("Enable DC braking"). As long as the DCBRK is ON, the inverter performs DC braking, regardless of the braking time specified by F22.  For details about DCBRK, refer to E01 through E07 (data = 13). Turning the DCBRK ON even when the inverter is in a stopped state activates the DC braking.
Page 379 6.3 Details of Function Codes F23 to F25 Starting Frequency 1, Starting Frequency 1 (Holding time), and Stop Frequency At the startup of an inverter, the initial output frequency is equal to the starting frequency. The inverter stops its output when the output frequency reaches the stop frequency. Set the starting frequency to a level at which the motor can generate enough torque for startup.
Page 380 F26, F27 Motor Sound (Carrier frequency and Tone) H98 (Protection/Maintenance Function, Mode selection) Motor Sound (Carrier frequency) (F26)  F26 controls the carrier frequency so as to reduce an audible noise generated by the motor or electromagnetic noise from the inverter itself, and to decrease a leakage current from the main output (secondary) wirings.
Page 381 6.3 Details of Function Codes F29 to F31 Analog Output [FM1] (Mode selection, Voltage adjustment, Function) F35 ([FM2] (Function)) These function codes allow terminal [FM1] to output monitored data such as the output frequency and the output current in an analog DC voltage or current. The magnitude of such analog voltage or current is adjustable.

Page 384 F32, F34, Pulse Output [FM2] (Mode selection, Voltage adjustment, Function) These function codes allow terminal [FM2] to output monitored data such as the output frequency and the output current in an analog DC voltage or current. The magnitude of such analog voltage or current is adjustable.
Page 385 V/f characteristics  The FRENIC-HVAC series of inverters offer a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans and pumps and for constant torque load (including special pumps requiring high starting torque). Two types of torque boosts are available: manual and automatic.
Page 386 When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low at a low frequency zone, resulting in insufficient output torque, depending on the characteristics of the motor and load. In such a case, it is recommended to increase the output voltage at the low frequency zone using the non-linear V/f pattern.
Page 387 6.3 Details of Function Codes • Auto torque boost This function automatically optimizes the output voltage to fit the motor with its load. Under light load, auto torque boost decreases the output voltage to prevent the motor from over-excitation. Under heavy load, it increases the output voltage to increase the output torque of the motor.
Page 388 F40, F41 Torque Limiter 1 (Driving, Braking) E16 and E17 (Torque Limiter 2 (Driving, Braking)) H76 (Torque Limiter for Braking, Frequency increment limit) If the inverter’s output torque exceeds the specified levels of the torque limiters (F40, F41, E16 and E17), the inverter controls the output frequency and limits the output torque for preventing a stall.
Page 389 6.3 Details of Function Codes Switching torque limiters  The torque limiters can be switched by the function code setting and the terminal command TL2/TL1 ("Select torque limiter level 2/1") assigned to any of the digital input terminals. To assign the TL2/TL1 as the terminal function, set any of E01 through E07 to "14." If no TL2/TL1 is assigned, torque limiter level 1 (F40 and F41) take effect by default.
Page 390 Drive Control Selection 1 H68 (Slip Compensation 1, Operating conditions) F42 specifies the motor drive control. Data for Basic Speed Drive control Speed control control feedback V/f control with slip compensation Frequency control inactive Dynamic torque vector control (with slip Disable control Frequency control...
Page 391 6.3 Details of Function Codes Dynamic torque vector control  To get the maximal torque out of a motor, this control calculates the motor torque matched to the load applied and uses it to optimize the voltage and current vector output. Selecting this control automatically enables the auto torque boost and slip compensation function so that it is effective for improving the system response to external disturbances such as load fluctuation, and the motor speed control accuracy.
Page 392 F43, F44 Current Limiter (Mode selection and Level) H12 (Instantaneous Overcurrent Limiting, Mode selection) When the output current of the inverter exceeds the level specified by the current limiter (F44), the inverter automatically manages its output frequency to prevent a stall and limits the output current.
Page 393 6.3 Details of Function Codes • If an excessive load is applied when the current limiter operation level is set extremely low, the inverter will rapidly lower its output frequency. This may cause an overvoltage trip or dangerous turnover of the motor rotation due to undershooting.

Page 448 Motor 1 (Auto-tuning) The inverter automatically detects the motor constants and saves them as parameters in its internal memory. Basically, no tuning is required as long as a Fuji standard motor is used with standard connection with the inverter. There are two types of auto-tuning as listed below. Select appropriate one considering the limitations in your equipment and control mode.

Page 671: Daily Inspection
10.1 Daily Inspection • Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least ten minutes. Make sure that the LCD monitor is turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

These parts are likely to deteriorate with age due to their constitution and properties, leading to the decreased performance or failure of the inverter. When the replacement is necessary, consult your Fuji Electric representative. Table 10.2 Replacement Parts Standard replacement intervals (See Note below.)
Page 674: Judgment On Service Life
10.3.1 Judgment on service life The inverter has the life prediction function for some parts which measures the discharging time or counts the voltage applied time, etc. The function allows you to monitor the current lifetime state on the LCD monitor and judge whether those parts are approaching the end of their service life. The life prediction function can also issue early warning signals if the life time alarm command LIFE is assigned to any of the digital output terminals.
Page 675 10.3 List of Periodic Replacement Parts The service life of the DC link bus capacitor can be judged by the "measurement of discharging time" or "ON-time counting." Measurement of discharging time of the DC link bus capacitor - The discharging time of the DC link bus capacitor depends largely on the inverter's internal load conditions, e.g.
Page 676 • Ensure that transistor output signals ([Y1] to [Y4]) and relay output signals ([Y5A/C] and [30A/B/C]) will not be turned ON. • Disable the RS-485 communications link. If negative logic is specified for the transistor output and relay output signals, they are considered ON when the inverter is not running.
Page 677 10.3 List of Periodic Replacement Parts Hereafter, each time the inverter is turned OFF, it automatically measures the discharging time of the DC link bus capacitor if the above conditions are met. Periodically check the relative capacitance of the DC link bus capacitor (%) with PRG > 3(INV Info) > 4(Maintenance) in Programming mode. The condition given above produces a rather large measurement error.
Page 678: Measurement Of Electrical Amounts In Main Circuit
10.4 Measurement of Electrical Amounts in Main Circuit Because the voltage and current of the power supply (input, primary circuit) of the inverter main circuit and those of the motor (output, secondary circuit) contain harmonic components, the readings may vary with the type of the meter. Use meters listed in Table 10.4 when measuring with meters designed for commercial frequencies.
Page 679: Insulation Test
A withstand voltage test may also damage the inverter if the test procedure is wrong. When the withstand voltage test is necessary, consult your Fuji Electric representative. (1) Megger test of main circuit 1) Use a 500 VDC Megger (*1) and shut off the main power supply without fail before measurement.

It is intended to apply to the domestic market only.
Page 725 Measure The influence of induction noise and radiation noise can be reduced by separating the PG signal lines and power lines. Providing noise filters at the input and output terminals is also an effective measure.
Page 726: Noise
App. A Advantageous Use of Inverters (Notes on electrical noise) Noise This section gives a summary of noises generated in inverters and their effects on devices subject to noise. [ 1 ] Inverter noise Figure A.1 shows an outline of the inverter configuration. The inverter converts AC to DC (rectification) in a converter unit, and converts DC to AC (inversion) with 3-phase variable voltage and variable frequency.
Page 727 [ 2 ] Types of noise Noise generated in an inverter is propagated through the main circuit wiring to the power supply and the motor so as to affect a wide range of applications from the power supply transformer to the motor. The various propagation routes are shown in Figure A.2.
Page 728: Noise Prevention
App. A Advantageous Use of Inverters (Notes on electrical noise) Figure A.5 Electrostatic Induced Noise (3) Radiation noise Noise generated in an inverter may be radiated through the air from wires (that act as antennas) at the input and output sides of the inverter so as to affect peripheral devices. This noise is called "radiation noise"...
Page 729 [ 2 ] Implementation of noise prevention measures There are two types of noise prevention measures--one for noise propagation routes and the other for noise receiving sides (that are affected by noise). The basic measures for lessening the effect of noise at the receiving side include: Separating the main circuit wiring from the control circuit wiring, avoiding noise effect.
Page 730 App. A Advantageous Use of Inverters (Notes on electrical noise) What follows is noise prevention measures for the inverter drive configuration. (1) Wiring and grounding As shown in Figure A.7, separate the main circuit wiring from control circuit wiring as far as possible regardless of being located inside or outside the system control panel containing an inverter.
Page 731 (3) Anti-noise devices To reduce the noise propagated through the electrical circuits and the noise radiated from the main circuit wiring to the air, a line filter and power supply transformer should be used (refer to Figure A.10). Line filters are available in these types--the simplified type such as a capacitive filter to be connected in parallel to the power supply line and an inductive filter to be connected in series to the power supply line and the orthodox type such as an LC filter to meet radio noise regulations.
