  • Page 24 When mounting two or more inverters Horizontal layout is recommended when two or more inverters are to be installed in the same unit or panel. If it is necessary to mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will not affect the one/s above.
  • Page 25 Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so that the logo "FRENIC-Multi" can be seen from the front. Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation efficiency of the inverter and cause the overheat protection function to operate, so the inverter will not run.

  • Page 101: Overview Of Function Codes

    5.2 Overview of Function Codes This section provides an overview of the function codes frequently used for the FRENIC-Multi series of inverter. For details about the function codes given below and other function codes not given below, refer to the FRENIC-Multi User’s Manual, Chapter 9 "FUNCTION CODES" and the RS-485 Communications User's Manual.
  • Page 102 Data for Function F01, C30 Enable the current input to terminal [C1] (C1 function) (+4 to +20 mA DC, maximum frequency obtained at +20 mA DC). Enable the sum of voltage (0 to +10 VDC) and current inputs (+4 to +20 mA DC) given to terminals [12] and [C1] (C1 function), respectively.
  • Page 103 • In addition to the run command sources described above, higher priority command sources including communications link are provided. For details, refer to the FRENIC-Multi User's Manual. Maximum Frequency 1 F03 specifies the maximum frequency to limit a reference frequency. Specifying the maximum frequency exceeding the rating of the equipment driven by the inverter may cause damage or a dangerous situation.
  • Page 104 Base Frequency 1 Rated Voltage at Base Frequency 1 Maximum Output Voltage 1 H50, H51 Non-linear V/f Pattern 1 (Frequency and Voltage) H52, H53 Non-linear V/f Pattern 2 (Frequency and Voltage) These function codes specify the base frequency and the voltage at the base frequency essentially required for running the motor properly.
  • Page 105 Examples: Normal (linear) V/f pattern V/f pattern with two non-linear points Acceleration Time 1 Deceleration Time 1 Acceleration Time 2 Deceleration Time 2 F07 specifies the acceleration time, the length of time the frequency increases from 0 Hz to the maximum frequency. F08 specifies the deceleration time, the length of time the frequency decreases from the maximum frequency down to 0 Hz.
  • Page 106 V/f pattern (factory default). V/f characteristics The FRENIC-Multi series of inverters offers 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 or for special pump load requiring high starting torque.
  • Page 107 When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low and insufficient voltage output may result in less output torque of the motor at a low frequency zone, depending on some characteristics of the motor itself and load.
  • Page 108 • 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 output torque of the motor.
  • Page 109 The figure below shows operating characteristics of the electronic thermal overload protection when F10 = 1. The characteristic factors 1 through 3 as well as their corresponding switching frequencies f and f vary with the characteristics of the motor. The tables below list the factors of the motor selected by P99 (Motor 1 Selection).
  • Page 110 Thermal time constant (F12) F12 specifies the thermal time constant of the motor. If the current of 150% of the overload detection level specified by F11 flows for the time specified by F12, the electronic thermal overload protection becomes activated to detect the motor overload. The thermal time constant for general-purpose motors including Fuji motors is approx.
  • Page 111 Restart Mode after Momentary Power Failure Restart Mode after Momentary Power Failure, Restart time Restart Mode after Momentary Power Failure, Frequency fall rate Restart Mode after Momentary Power Failure, Allowable momentary power failure time F14 specifies the action to be taken by the inverter such as trip and restart in the event of a momentary power failure.
  • Page 112 Restart mode after momentary power failure (Basic operation) The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below the undervoltage detection 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 113 During a momentary power failure, the motor slows down. After power is restored, the inverter restarts at the frequency just before the momentary power failure. Then, the current limiting function works and the output frequency of the inverter automatically decreases. When the output frequency matches the motor speed, the motor accelerates up to the original output frequency.
  • Page 114 Follow data specified by H14 Follow the setting of the PI controller in the current limiter (of the current limit control block shown in FRENIC-Multi User's Manual, Chapter 4, Section 4.4, Figure 4.3.1 "). (The PI constant is prefixed inside the inverter.) he frequency fall rate is too high, regeneration may take place at the moment the motor rotation matches the inverter output frequency, causing an overvoltage trip.
  • Page 115 Bias (Frequency command 1) Bias (for Frequency 1) (Bias base point) C32, C34 Analog Input Adjustment for [12] (Gain, Gain base point) C37, C39 Analog Input Adjustment [C1] (Gain, Gain base point) C42, C44 Analog Input Adjustment [V2] (Gain, Gain base point) When any analog input for frequency command 1 (F01) is used, it is possible to define the relationship between the analog input and the reference frequency by multiplying the gain and adding the bias specified by F18.
  • Page 116 (Point A) To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is the bias base point and it is equal to 10% of 10 V (full scale), set the bias base point to 10% (C50 = 10).
  • Page 117 In general, specify data of function code F20 at a value close to the rated slip frequency of motor. If you set it at an extremely high value, control may become unstable and an overvoltage alarm may result in some cases. The DC brake function of the inverter does not provide any holding mechanism.
  • Page 118 Specifying a too low carrier frequency will cause the output current waveform to have a large amount of ripples. As a result, the motor loss increases, causing the motor temperature to rise. Furthermore, the large amount of ripples tends to cause a current limiting alarm.

  • Page 120 The torque limiter and current limiter are very similar function each other. If both are activated concurrently, they may conflict each other and cause a hunting in the system. Avoid concurrent activation of these limiters. Control Mode Selection 1 Slip Compensation 1 (Operating conditions) F42 specifies the control mode of the inverter to control a motor.
  • Page 121 In the slip compensation and dynamic torque vector control, the inverter uses the motor parameters to control its speed. Therefore, the following conditions should be satisfied; if not, the inverter may not get the proper performance from the motor. • A single motor should be controlled. (It is difficult to apply this control to a group motor driving system.) •...
