    (3) Mounting direction Secure the inverter to the mounting base with four screws or bolts (M4) so that the FRENIC-Mini logo faces outwards. Tighten those screws or bolts perpendicular to the mounting base. 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.

    2.3.7 Wiring for control circuit terminals In general, sheaths and covers of the control signal cables and wires are not specifically designed 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.

    FUNCTION CODES 5.1 Function Code Tables Function codes enable the FRENIC-Mini series of inverters to be set up to match your system requirements. Each function code consists of a 3-letter string. The first letter is an alphabet that identifies its group and the following two letters are numerals that identify each individual code in the group.
  • Page 84 Using negative logic for programmable I/O terminals The negative logic signaling system can be used for the digital input and output terminals by setting the function codes specifying the properties for those terminals. Negative logic refers to inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An ON-active signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to OFF-active signal (the function takes effect if the terminal is opened.) in the negative logic system.

    5.2 Overview of Function Codes This section provides an overview of the function codes frequently used for the FRENIC-Mini series of inverter. For details about the function codes given below and other function codes not given below, refer to the FRENIC-Mini User’s Manual (MEH446), Chapter 9 "FUNCTION CODES" and the RS485 Communications User's Manual (MEH448).
  • Page 96 Running/Stopping and Rotational Direction Selects a source issuing a run command--keypad or external control signal input. - If F02 = 0, 2, or 3, the inverter can run the motor by the keys on the built-in keypad. The motor rotational direction can be specified in two ways, either by control signal input (F02 = 0) or by use of prefixed forward or reverse rotation (F02 = 2 or 3).
  • Page 97 • If you have assigned the (FWD) or (REV) function to the [FWD] or [REV] terminal, you cannot change the setting of function code F02 while the terminals [FWD] and [CM]* or the terminals [REV] and [CM]* are short-circuited. • If you have specified the external signal (F02=1) as the running command and have assigned functions other than the (FWD) or (REV) function to the [FWD] or [REV] terminal, caution should be exercised in changing the settings.
  • Page 98 If F05 is set to match the rated voltage of the motor, motor efficiency will be better than that it is set to 0. Therefore, when brakes are applied to the motor, energy loss decreases and the motor regenerates larger braking energy, which can easily cause the overvoltage protection function ( where n=1 to 3) to be activated.
  • Page 99 V/f pattern with single non-linear point inside the base frequency You can also set the optional non-linear V/f range (H50: Frequency) for frequencies exceeding the base frequency (F40). Acceleration Time 1, Deceleration Time 1 The acceleration time specifies the length of time the frequency increases from 0 Hz to the maximum frequency.
  • Page 100 In case the set frequency is lower than the maximum frequency (F03) The actual acceleration and deceleration times are shorter than the specified acceleration time and deceleration time. • If you choose S-curved acceleration/deceleration or curvilinear acceleration/deceleration in "curvilinear acceleration/deceleration" (H07), the actual acceleration/deceleration times are longer than the specified times.
  • Page 101 Manual torque boost In manual torque boost mode, the inverter maintains the output at a constant level regardless of the load. When you use this mode, select the appropriate V/f pattern (variable torque or constant torque characteristics) with Load Selection (F37). To keep the motor starting torque, manually select optimal inverter output voltage for the motor and load by setting an optimal torque boost rate to F09 in accordance with the motor and its load.
  • Page 102 Use auto-energy saving only where the base frequency is 60 Hz or lower. If the base frequency is higher than 60 Hz, then you may get little or no energy saving effect. The auto energy saving operation is designed for use with the frequency lower than the base frequency.

  • Page 106 • When you change the upper frequency limit (F15) in order to increase the running frequency, be sure to change the maximum frequency (F03) accordingly. • Maintain the following relationship among the parameters for frequency control: F03 F15 > F16 F23 F25, or F03 F15 > F16 F25 F23, where, F23 is the starting frequency and F25 is the stopping frequency.
  • Page 107 When using the function codes for setting a gain or bias alone without changing any reference points, the setting procedure for the function codes is the same as that of Fuji conventional inverter models (FVR-C9S, FVR-C11S, etc.). F20 to F22...

(The torque may not be sufficient at the start of DC braking.) Quick response The DC braking current quickly ramps up. (Depending on the inertia of the moving loads or the coupling state, the revolution may be unstable.) For three-phase 200V and single-phase 200V/100V series inverters...
  • Page 109 F23, F25 Starting Frequency and Stopping Frequency At the startup of an inverter, the initial output frequency is equal to the starting frequency. The inverter stops its output at the stop frequency. Set the starting frequency to a level that will enable the motor to generate enough torque for startup.
  • Page 110 Terminal [FMA] (Gain to output voltage) Analog Output Signal Selection for [FMA] (Monitor object) F31 allows you to output monitored data (such as the output frequency or output current) to terminal [FMA] as an analog DC voltage that can be adjusted with F30 for the meter scale.
  • Page 111 For three-phase 200 V and single-phase 200 V/100 V series of inverters Outputting the output current in an analog format (FMA) (F31 = 2) The analog output terminal [FMA] outputs 10 V, that is, 200% of the reference current I (A), supposing the output gain selected with F30 as 100%.

  • Page 119 Switch Normal/Inverse operation--(IVS) (Function code data = 21) Turning the (IVS) command on/off switches the output frequency control between normal (proportional to the set frequency components) and inverse operation for the PID process or manually set frequencies. To select the inverse operation, turn the (IVS) command on.
  • Page 120 E20, E27 Status Signal Assignment to [Y1], [30A], [30B] and [30C] E20 and E27 may assign output signals to terminals [Y1] (transistor switch) and [30A], [30B] and [30C] (mechanical relay contacts) which are general-purpose programmable output 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 121 Undervoltage detection--(LU) (Function code data = 3) This signal is turned on when the DC link circuit voltage of the inverter drops below the specified level or when the motor stops due to activation of the undervoltage protection feature (undervoltage trip). It is turned off if the DC link circuit voltage exceeds the specified level.

    11.4 Harmonic Component Regulation in the EU 11.4.1 General comments When you use general-purpose industrial inverters in the EU, the harmonics emitted from the inverter to power lines are strictly regulated as stated below. If an inverter whose rated input is 1 kW or less is connected to public low-voltage power supply, it is regulated by the harmonics emission regulations from inverters to power lines (with the exception of industrial low-voltage power lines).
