Page 6: Safety Precautions
Fire or an accident could occur. • FRENIC-Mini may not be used for a life-support system or other purposes directly related to the human safety. • Though FRENIC-Mini is manufactured under strict quality control, install safety devices for applications where serious accidents or material losses are foreseen in relation to the failure of it.
Page 7 • 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 8 • 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 9 (Design the machinery or equipment so that human safety is ensured after restarting.) • If you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
Page 10 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 11: Conformity To The Low Voltage Directive In The Eu
Conformity to the Low Voltage Directive in the EU If installed according to the guidelines given below, inverters marked with CE are considered as compliant with the Low Voltage Directive 2006/95/EC. 1.

Page 98: Details Of Function Codes
5.2 Details of Function Codes This section provides the details of the function codes frequently used for the FRENIC-Mini series of inverters. For details about the function codes given below and other function codes not given below, refer to the FRENIC-Mini User’s Manual (24A7-E-0023), Chapter 9 "FUNCTION CODES."...
Page 99 In addition to the frequency command sources described above, higher priority command sources including communications link and multistep frequency are provided. For details, refer to the block diagram given in FRENIC-Mini User's Manual (24A7-E-0023), Chapter 4, Section 4.2 "Drive Frequency Command Generator."...
Page 100 • In addition to the run command sources described above, higher priority command sources including communications link are provided. For details, refer to the FRENIC-Mini User's Manual (24A7-E-0023). Maximum Frequency 1 F03 specifies the maximum frequency (for motor 1) 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.
Page 101 Base Frequency 1 (F04) Set the rated frequency printed on the nameplate labeled on the motor. 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 102 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 103 V/f pattern (factory default). V/f characteristics The FRENIC-Mini 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 104 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. Specify an appropriate level that guarantees smooth start-up and yet does not cause over-excitation with no or light load.
Page 105 • 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.

Data for F10 Function For a general-purpose motor and Fuji standard permanent magnet synchronous motor with shaft-driven cooling fan. (The cooling effect will decrease in low frequency operation.)

Page 108 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 109 Data for F14 Mode Description Trip after As soon as the DC link bus voltage drops below the decelerate-to-stop 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 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 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 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) 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 It is also possible to use an external digital input signal as an "Enable DC braking" terminal command DCBRK. As long as the DCBRK command is ON, the inverter performs DC braking, regardless of the braking time specified by F22. Turning the DCBRK command ON even when the inverter is in a stopped state activates DC braking.
Page 116 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.
Page 117 Analog Output [FMA] (Voltage adjustment) Analog Output [FMA] (Function) These function codes allow terminal [FMA] to output monitored data such as the output frequency and the output current in an analog DC voltage. The magnitude of the output voltage is adjustable. Voltage adjustment (F30) F30 adjusts the output voltage representing the monitored data selected by F31 within the range of 0 to 300%.
Page 118 Control Mode Selection 1 F42 specifies the control mode of the inverter to control a motor. 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 for PMSM drive 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 119 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 120 Set F50 and F51 data to the discharging capability and allowable average loss, respectively.
