The MCB (Molded Case Circuit Breaker) could trip when powering on the FujiFilm FVR-Micro due to:

1. Overcurrent at power-on caused by inrush current or wiring issues.
2. Use of an MCCB with a capacity exceeding the recommended rating.
3. Faults in the inverter such as short circuits or internal component failures.
4. Improper grounding or wiring errors.
5. Power supply issues like incorrect voltage or frequency.

These factors can trigger the protective device to disconnect power to prevent damage.

Page 4 Preface Thank you for purchasing our FVR-Micro of inverters. This product is designed to drive a three-phase induction motor. Read through this instruction manual and be familiar with proper handling and operation of this product. Improper handling might result in incorrect operation, a short life, or even a failure of this product as well as the motor.
Page 5: Safety Precautions
These safety precautions are of utmost importance and must be observed at all times. Application • FVR-Micro is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other purposes. Fire or an accident could occur.
Page 6 • Do not support the inverter by its terminal block cover during transportation. Doing so could cause a drop of the inverter and injuries. • Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink. Otherwise, a fire or an accident might result.
Page 7 • Generally, control signal wires are not reinforced insulation. If they accidentally touch any of live parts in the main circuit, their insulation coat may break for any reasons. In such a case, an extremely high voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from contacting any hot high voltage lines.
Page 8 • If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or 5), then the inverter automatically restarts running the motor when the power is recovered. (Design the machinery or equipment so that human safety is ensured after restarting.) •...
Page 9: General Precautions
Disposal • Handle the inverter as an industrial waste when disposing of it. Otherwise injuries could occur. Others • Never attempt to modify the inverter. Doing so could cause electric shock or injuries. GENERAL PRECAUTIONS Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts.

Page 20 The wiring procedure for the FVR0.75AS1S-4 is given below as an example. For other inverter types, perform wiring in accordance with their individual terminal arrangement. ① Grounding terminal ( G) Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipulated by the Electric Facility Technical Standard that all metal frames of electrical equipment must be grounded to avoid electric shock, fire and other disasters.
Page 21 Driving 400 V series motor • If a thermal relay is installed in the path between the inverter and the motor to protect the motor from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m. In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code F26: Motor sound (Carrier frequency)).
Page 22: Wiring For Control Circuit Terminals
2.3.6 Wiring for control circuit terminals In general, sheaths and covers of the control signal cables and wires are not specifically de- signed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit.

There is no need to specify the rotation direction. • When function code F02 = 0 or 1, the "Run forward" FWD and "Run reverse" REV terminal commands must be assigned to terminals [FWD] and [REV], respectively.
Page 56  Rated Voltage at Base Frequency (F05) Set "0" or the rated voltage printed on the nameplate labeled on the motor. - If "0" is set, the rated voltage at base frequency is determined by the power source of the inverter.

Page 57  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 58 V/f pattern (factory default).  V/f characteristics The FVR-Micro 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 59  Torque boost • Manual torque boost (F09) In torque boost using F09, constant voltage is added to the basic V/f pattern, regardless of the load, to give the output voltage. To secure a sufficient starting torque, manually adjust the output voltage to optimally match the motor and its load by using F09.
Page 60 • 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 62  Overload detection level (F11) F11 specifies the detection level (in amperes) at which the electronic thermal overload protection becomes activated. In general, set F11 to the rated current of motor when driven at the base frequency (i.e. 1.0 to 1.1 multiple of the rated current of motor 1 (P03)).
Page 63 Example of Thermal Overload Detection Characteristics Restart Mode after Momentary Power Failure Restart Mode after Momentary Power Failure, Restart time Restart Mode after Momentary Power Failure, Frequency fall rate F14 specifies the action to be taken by the inverter such as trip and restart in the event of a momentary power failure.
Page 64 Data for F14 Mode Descri Trip after decelerate- As soon as the DC link bus voltage drops below to-stop the continuous running level due to a momentary power failure, decelerate-to-shop control is invoked. Decelerate-to-stop control regenerates kinetic energy from the load's moment of inertia, slowing down the motor and continuing the deceleration operation.
Page 65  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 under voltage 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 66 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 67  Restart mode 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 68 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) 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 69 (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 70 [Conversion formula] × 100 Setting value (%) = Example: If setting I (A) of 4.2 A with standard applicable motor capacity of 0.75 kW 4.2 (A) × 100 = 84 Setting value (%) = 5.0 (A)  Braking time (F22) F22 specifies the braking period that activates DC braking.
Page 71 Starting Frequency 1 Starting Frequency 1 (Holding time) Stop Frequency Stop Frequency (Holding time) At the startup of an inverter, the initial output frequency is equal to the starting frequency 1 specified by F23. The inverter stops its output when the output frequency reaches the stop frequency specified by F25.
Page 72 F26,F27 Motor Sound (Carrier frequency and tone)  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.

Data for F42 Control mode V/f control with slip compensation inactive Dynamic torque vector control V/f control with slip compensation active  V/f control In this control, the inverter controls a motor by the voltage and frequency according to the V/f pattern specified by function codes.
Page 75 F43,F44 Current Limiter (Mode selection, Level) 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 limit the output current. (Refer to the description of function code H12.) If F43 = 1, the current limiter is enabled only during constant speed operation.
Page 76 F50,F51 Electronic Thermal Overload Protection for Braking Resistor (Discharging capability and Allowable average loss) A braking resistor can be mounted on inverters of 0.4 kW or above. These function codes specify the electronic thermal overload protection feature for the braking resistor. Set F50 and F51 data to the discharging capability and allowable average loss, respectively.
Page 77  External Braking Resistors Standard models The thermal sensor relay mounted on the braking resistor acts as a thermal protector of the motor for overheat, so assign an "Enable external alarm trip" terminal command THR to any of digital input terminals [X1] to [X3], [FWD] and [REV] and connect that terminal and its common terminal to braking resistor's terminals 2 and 1.
Page 78 E01 to E03 Terminal [X1] to [X3] Function E98, E99 Terminal [FWD] and [REV] Function Function codes E01 to E03, E98 and E99 allow you to assign commands to terminals [X1] to [X3], [FWD], and [REV] which are general-purpose, programmable, digital input terminals. These function codes may also switch the logic system between normal and negative to define how the inverter logic interprets either ON or OFF status of each terminal.
Page 79 Terminal function assignment and data setting  Select multistep frequency (0 to 15 steps) -- SS1, SS2, SS4, and SS8 (Function code data = 0, 1, 2, and 3) The combination of the ON/OFF states of digital input signals SS1, SS2, SS4 and SS8 selects one of 16 different frequency commands defined beforehand by 15 function codes C05 to C19 (Multistep frequency 0 to 15).
Page 80  Enable 3-wire operation -- HLD (Function code data = 6) Turning this terminal command ON self-holds the forward FWD or reverse REV run command issued with it, to enable 3-wire inverter operation. Short-circuiting the terminals between HLD and [CM] (i.e., when HLD is ON) self-holds the first FWD or REV command at its leading edge.
Page 81  Ready for jogging -- JOG (Function code data = 10) This terminal command is used to jog or inch the motor for positioning a work piece. Turning this command ON makes the inverter ready for jogging. Simultaneous keying keys on the keypad is functionally equivalent to this command; however, it is restricted by the run command source as listed below.
Page 82  Enable DC braking -- DCBRK (Function code data = 13) This terminal command gives the inverter a DC braking command through the inverter’s digital input.(Refer to the descriptions of F20 to F22.)  UP (Increase output frequency) and DOWN (Decrease output frequency) commands -- UP and DOWN (Function code data = 17, 18) •...
Page 83 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 84  Enable communications link via RS-485 -- LE (Function code data = 24) Turning this terminal command ON assigns priorities to frequency commands or run commands received via the RS-485 communications link (H30). No LE assignment is functionally equivalent to the LE being ON. (Refer to the description of H30.) ...

Page 87  Inverter running 2 -- RUN2 (Function code data = 35) This signal acts in the same way as RUN (Function code data = 0) except that RUN2 is ON even when the DC braking is in operation.  Overload prevention control -- OLP (Function code data = 36) This output signal comes ON when the overload prevention control is activated.
Page 88  Motor overheat detected by thermistor (PTC) -- THM (Function code data = 56) When the thermistor is enabled (H26 = 2), this output signal comes ON if the motor temperature rises to the protection trigger level specified by H27. ...

Page 93 Motor 1 (Auto-tuning) The inverter automatically detects the motor parameters and saves them in its internal memory. Basically, it is not necessary to perform tuning when using a Fuji standard motor with a standard connection with the inverter. In any of the following cases, perform auto-tuning since the motor parameters are different from those of Fuji standard motors so as not to obtain the best performance under each of these controls-- auto torque boost, torque calculation monitoring, auto energy saving operation, automatic deceleration (anti-regenerative control), slip compensation, and torque...

Page 96 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 97 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 99 Instantaneous Overcurrent Limiting (Mode selection) H12 specifies whether the inverter invokes the current limit processing or enters the overcurrent trip when its output current exceeds the instantaneous overcurrent limiting level. Under the current limit processing, the inverter immediately turns OFF its output gate to suppress the further current increase and continues to control the output frequency.
Page 100 When H69 = 1: The anti-regenerative control is functionally equivalent to that of the original FVR-Micro. That is, when the DC link bus voltage exceeds the preset voltage limiting level, the inverter lengthens the deceleration time to three times the specified time to decrease the deceleration torque to 1/3.
Page 101 Data for H69 Function Disable Enable (Lengthen the deceleration time to three times the specified time under voltage limiting control.) Enable (Torque limit control: Disable force-to-stop processing.) Enabling the anti-regenerative control may automatically increase the deceleration time. When a braking resistor is connected, disable the anti-regenerative control. Automatic Overload Prevention Control H70 specifies the decelerating rate of the output frequency to prevent a trip from occurring due to an overload.
Page 102 Cumulative Run Time of Motor 1 Operating the keypad can display the cumulative run time of motor 1. This feature is useful for management and maintenance of the machinery. Using H94 can modify the cumulative run time of the motor to the desired value to be used as an arbitrary initial data. Specifying "0" clears the cumulative run time.
