  • Braking signal function making the FRENIC-Mini applicable to simple vertical lift applications The upgraded FRENIC-Mini series supports brake ON/OFF signals that are conventionally supported by the upper inverter series only. The braking signal function enables the FRENIC-Mini to be applied to simple vertical lift applications. • Motor switching function Turning the Di terminal ON and OFF switches between parameters specified for the 1st motor and those for the 2nd motor.

• Page 18
  • Braking resistor connectable to the inverter FRENIC-Mini series of inverters features a built-in braking transistor (for inverters of 0.4 kW (1/2 HP) or larger), which makes it possible for an optional braking resistor to be connected to increase the regenerative braking ability for conveyance and transportation machinery that requires strong braking power.
• Page 19
  To minimize the total loss (motor loss plus inverter loss), rather than just the motor loss as in the predecessor models, FRENIC-Mini saves even more power when used with fans or pumps. Refer to Chapter 4, Section 4.7 «Drive Command Controller» for details.

  Using negative logic for programmable I/O terminals The negative logic signaling system can be used for digital input terminals and transistor 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 signals. 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.

F08 specifies the deceleration time, the length of time the frequency decreases from the maximum frequency down to 0 Hz.

  9.2 Details of Function Codes 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. Two types of torque boost are available: manual and automatic.
• Page 228
  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 229
  9.2 Details of Function Codes Auto energy saving operation This feature automatically controls the supply voltage to the motor to minimize the total power loss of motor and inverter. (Note that this feature may not be effective depending upon the motor or load characteristics. Check the advantage of energy saving before actually apply this feature to your power system.) This feature applies to constant speed operation only.

  The figure below shows operating characteristics of the electronic thermal overload protection when F10 = 1. The characteristic factors α through α as well as their corresponding output frequencies f and f vary with the characteristics of the motor. The tables below list the factors determined by the motor capacity (P02) and the motor characteristics (P99).
• Page 231
  9.2 Details of Function Codes Overload detection level (F11) F11 specifies the detection level (in amperes) at which the electronic thermal overload protection becomes activated. In general, set the F11 data to the allowable continuous current of motor when driven at the base frequency (i.e.

  Restart Mode after Momentary Power Failure (Mode selection) H13 (Restart time) H14 (Frequency fall rate) H15 (Continuous running level) H92 (Continuity of Running, P) H93 (Continuity of Running, I) F14 specifies the action to be taken by the inverter such as trip and restart in the event of a momentary power failure.
• Page 233
  9.2 Details of Function Codes 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 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 234
  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 235
  9.2 Details of Function Codes Factory default By factory default, H13 is set at one of the values shown below according to the inverter capacity. Basically, you do not need to change H13 data. However, if the long restart time causes the flow rate of the pump to overly decrease or causes any other problem, you might as well reduce the setting to about a half of the default value.
• Page 236
  When the input power voltage for the inverter is extremely low, continuous running control might be activated even during normal operation, at the beginning of acceleration or at an abrupt change in load. To avoid this, lower the continuous running level. Lowering it too low, however, might cause undervoltage that results from voltage drop due to a control delay.
• Page 237
  9.2 Details of Function Codes Bias (Frequency command 1) C50, C32, C34, C37 and C39 (Bias base point, Gain, and 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 238
  Example: Setting the bias, gain and their base points when the reference frequency 0 to 100% follows the analog input of 1 to 5 VDC to terminal [12] (in frequency command 1). (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).

  9.2 Details of Function Codes DC Braking 1 (Braking starting frequency) H95 (DC Braking, Braking response mode) A09 (DC Braking 2, Braking starting frequency) DC Braking 1 (Braking level) A10 (DC Braking 2, Braking level) DC Braking 1 (Braking time) A11 (DC Braking 2, Braking time) F20 through F22 specify the DC braking that prevents motor 1 from running by inertia during decelerate-to-stop operation.
• Page 240
  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.

  9.2 Details of Function Codes Starting Frequency 1 A12 (Starting Frequency 2) Starting Frequency 1 (Holding time) Stop Frequency F39 (Stop Frequency, Holding time) At the startup of an inverter, the initial output frequency is equal to the starting frequency 1 specified by F23.

  Motor Sound (Carrier frequency) Motor Sound (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.

  They are also compatible in the terminal names, number of terminals, main circuit terminal position, and applicable wire sizes. The differences between the original FRENIC-Mini and upgraded one include the following screws and RJ-45 connector. The screw type on the control circuit terminal block changes from a Phillips-head screw to slotted one and the lower terminal block shifts 2 mm to the left.
