  • Page 4: Safety Precautions

    These safety precautions are of utmost importance and must be observed at all times. Application • FRENIC-Mini is designed to drive a three-phase induction motor. Do not use it for sin- gle-phase motors or for other purposes. Fire or an accident could occur.
  • Page 5 • 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 6 • 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 7 (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 8: General Precautions

    • 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.
  • Page 9 Conformity to the Low Voltage Directive in the EU If installed according to the guidelines given below, inverters marked with CE or TÜV are considered as compliant with the Low Voltage Directive 73/23/EEC. 1. The ground terminal G should always be connected to the ground.

    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 83 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 code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to active-OFF 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 RS-485 Communication User's Manual (MEH448).
  • Page 95 Operation Method 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, ei- ther by control signal input (F02 = 0) or by use of prefixed forward or reverse rotation (F02 = 2 or 3).
  • Page 96 • 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 97 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 = ) to be activated.
  • Page 98 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 99 In case the reference frequency is lower than the maximum frequency (F03) The actual acceleration and deceleration times are shorter than the specified ac- celeration time and deceleration time. • If you choose S-curved acceleration/deceleration or curvilinear accel- eration/deceleration in "curvilinear acceleration/deceleration" (H07), the actual acceleration/deceleration times are longer than the specified times.
  • Page 100 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 101 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 102 5 minutes by factory default. Data entry range: 0.5 to 75.0 (minutes, in 0.1-minute increment) Refer to the FRENIC-Mini User’s Manual (MEH446), Chapter 9 "FUNCTION CODES" for details of the shaft-driven cooling fan and characteristics of the electronic thermal function.
  • Page 103 - Trip immediately (F14 = 0) If a momentary power failure occurs when the inverter is in Running mode so that the inverter detects undervoltage of the DC link bus, then the inverter immediately stops its output and displays the undervoltage alarm on the LED monitor.
  • Page 104 This setting is optimal for operations in which the motor speed quickly slows down to 0 r/min due to the heavy load with a very small moment of inertia if the motor coasts to a stop because of the momentary power failure. •...
  • Page 105 • 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 H95 specifies the DC braking response mode as follows: If H95 is Braking mode Meaning set to: The DC braking current gradually ramps up. (The torque Slow response may not be sufficient at the start of DC braking.) The DC braking current quickly ramps up. (Depending on Quick response the inertia of the moving loads or the coupling state, the revolution may be unstable.)
  • Page 108 F23, F25 Starting Frequency and Stop 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 109 Analog Output [FMA] (Voltage adjustment and Function) 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. Voltage adjustment (F30) Adjust the output voltage level within the range of 0 to 200%, supposing the monitored amount of the monitor selected with function code F31 as 100%.
  • Page 110 For three-phase 200 V and single-phase 200 V/100 V class 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 ref- erence current I (A), supposing the output gain selected with F30 as 100%.

  • Page 117 If the PID control is disabled with the Hz/PID being off, the inverter runs the motor with the frequency manually set by any of multistep, keypad, or analog input. Refer to the FRENIC-Mini User's Manual (MEH446), Chapter 4, Section 4.8 "PID Frequency Command Generator" for details.
  • Page 118 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 reference frequency components) and inverse operation for the PID process or manually reference frequencies. To select the inverse op- eration, turn the IVS command on.
  • Page 119 Terminal [Y1] Function E20, E27 Terminal [30A/B/C] Function 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 120 Undervoltage detected--LU (Function code data = 3) This signal is turned on when the DC link bus voltage of the inverter drops below the specified level or when the motor stops due to activation of the undervoltage pro- tection feature (undervoltage trip).

    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).
