Page 23 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 24 (3) Mounting direction Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so that the logo "Jaguar VXR" 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 99: Overview Of Function Codes
5.2 Overview of Function Codes This section provides an overview of the function codes frequently used for the Jaguar VXR series of inverter. Data Protection F00 specifies whether to protect function code data (except F00) and digital reference data (such as frequency command, PID command and timer operation) from accidentally getting changed by pressing the keys.
Page 100 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 101 Operation Method F02 selects the source that specifies a run command for running the motor. Data for F02 Run Command Source Description Enables the keys to run and stop the motor. Keypad The rotation direction of the motor is specified by (Rotation direction terminal command FWD or REV.
Page 102 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 103 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 104 • If you choose S-curve acceleration/deceleration or curvilinear acceleration/ deceleration Acceleration/Deceleration Pattern (H07), actual acceleration/deceleration times are longer than the specified times. Refer to the description of H07 for details. • Specifying an improperly short acceleration/deceleration time may activate the current limiter, torque limiter, or anti-regenerative control, resulting in a longer acceleration/deceleration time than the specified one.
Page 105 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 106 • 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 107 The figure below shows operating characteristics of the electronic thermal overload protection α α 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 108 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 is approx.
Page 109 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 110 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 111 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 112 Restart after momentary power failure (Frequency fall rate) (H14) During restart after a momentary power failure, if the inverter output frequency and the idling motor speed cannot be harmonized with each other, an overcurrent will flow, activating the overcurrent limiter. If it happens, the inverter reduces the output frequency to match the idling motor speed according to the reduction rate (Frequency fall rate: Hz/s) specified by H14.
Page 113 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 114 (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 115 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 116 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 117 Function (F31) F31 specifies what is output to analog output terminal [FM].

Page 118 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 119 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.) •...

Page 128 The UP/DOWN control is available in two modes--one mode (H61 = 0) in which the initial value of the reference frequency is fixed to "0.00" at the start of the UP/DOWN control and the other mode (H61 = 1) in which the reference frequency applied in the previous UP/DOWN control applies as the initial value.

Page 141 H04, H05 Auto-reset (Times and Reset interval) H04 and H05 specify the auto-reset function that makes the inverter automatically attempt to reset the tripped state and restart without issuing an alarm (for any faults) even if any protective function subject to reset is activated and the inverter enters the forced-to-stop state (tripped state).
Page 142 Cooling Fan ON/OFF Control To prolong the life of the cooling fan and reduce fan noise during running, the cooling fan stops when the temperature inside the inverter drops below a certain level while the inverter stops. However, since frequent switching of the cooling fan shortens its life, the cooling fan is kept running for 10 minutes once it is started.

Page 146 Droop Control In a system in which two or more motors drive single machinery, any speed gap between inverter-driven motors results in some load unbalance between motors. The droop control allows each inverter to drive the motor with the speed droop characteristics for increasing its load, eliminating such kind of load unbalance.

Page 148 Mock Alarm Clear Alarm Data H45 causes the inverter to generate a mock alarm in order to check whether external sequences function correctly at the time of machine setup. Setting the H45 data to "1" displays mock alarm on the LED monitor and issues alarm output ALM to the digital output terminal specified (see E20, E21 and E27).
Page 149 Overload Prevention Control H70 specifies the decelerating rate of the output frequency to prevent a trip from occurring due to an overload. This control decreases the output frequency of the inverter before the inverter trips due to a heat sink overheat or inverter overload (with an alarm indication of respectively).
