Wiring method

Power supply connection

  1. Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with neighboring wires. If the length is too short, wires might come off.
    Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it
    Power supply connection Step 1
  2. Crimp the blade terminal.
    Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or the face is damaged.Power supply connection Step 2Blade terminals commercially available (as of February 2017)

Wiring of the control circuit

Recommended cable gauge: 0.3 to 0.75 mm2
Wiring of the control circuit

Input signals

Use a wire end ferrule and a cable for the connection to the terminals where the end is striped appropriately. Single-core cables can be connected directly to the terminals after removing the insulation.

Terminal Description
STF Forward rotation start signal
STR Reverse rotation start signal
RH, RM, RL Multi-speed selection

Common terminal for the contact input terminal (sink logic).

Common terminal (0 V) for the 24 V DC power supply (terminal PC).

PC 24 V DC output and common terminal for control circuit inputs in source logic
Terminal Type Description
10 Frequency setting power supply Used as the power supply for an external device such as a frequency setting potentiometer or digital panel meter.
2 Frequency setting (voltage) Inputting 0 to 5 V DC (or 0 to 10 V DC) provides the maximum output frequency at 5 V (or 10 V) and makes input and output proportional.
4 Frequency setting (current) Inputting 4 to 20 mA DC Current input Voltage (or 0 to 5 V, 0 to 10 V) (initial status) input provides the maximum output frequency at 20 mA and makes input and output proportional. This input signal is valid only when the AU signal is ON (terminal 2 input is invalid).
5 Frequency setting and analog outputs common Terminal 5 represents the reference point (0 V) for all analog setpoint values and for the analog output signal AM (voltage). The terminal is isolated from the reference potential of the digital circuit (SD).
10 PTC input (PTC sensor) Terminals 10 and 2 serve as an input for a PTC sensor (thermal motor protection).
A, B, C Relay output A changeover contact output that indicates that an inverter's protective function has been activated and the outputs are stopped.
RS-485 PU interface The PU connector supports the RS-485 communication.

Components of the operation panel

Components of the operation panel

Appearance Name Description
STOP/ RESET key Stops the operation commands. Used to reset the inverter when the protective function is activated.
UP/DOWN key Used to change the setting of frequency or parameter, etc. The following operations are also enabled:
  • Displaying the present setting during calibration
  • Displaying a fault record number in the fault history

MODE key
Switches the monitor screen (item) in the monitor mode. Every key on the operation panel becomes inoperable (locks) by holding this key for 2 seconds. The key lock function is disabled when Pr.161 = "0 (initial value)". Holding this key for one second displays the initial screen. (During normal inverter operation it will appear as the first screen in the monitor mode; during abnormal operation it will appear as the first screen in the fault history mode. Reverts to the previous screen if pressed during frequency setting when the easy setting function is enabled.
SET key Confirms each selection. Pressing this key in a mode other than the parameter setting mode will display parameter settings.
RUN key Used to give the start command to the inverter. The rotation direction depends on the Pr.40 setting.

Basic operation

Basic operation

  1. The monitor items can be changed.
  2. In each fault record display, "0" is displayed instead of the fault indication when no fault record exists.
  3. "P. 0" will appear if the MODE key is pressed during parameter setting.

Changing the parameter setting value

Change the setting of Pr.1 Maximum frequency.

Operating procedure

  1. Turning ON the power of the inverter
    The operation panel is in the monitor mode.
  2. Selecting the parameter setting mode
    Press to choose the parameter setting mode.
  3. Selecting the parameter
    Press or to show
    (Pr.1). Press to read the present set value.
    (initial value) appears.
  4. Changing the setting value
    Press or change the set value to . Press to enter the setting and
    are displayed alternately.
  • Press or to read another parameter.
  • Press to show the setting again.
  • Press twice to show the next parameter.
  • Press for one second to return the display to the first screen in the monitor mode (the monitor item initially set in the first screen is the frequency).


  • If a parameter write condition is not satisfied, a parameter write error appears on the LCD display. N
  • When Pr.77 Parameter write selection = "2 (initial value)", the parameter setting change is available only while the inverter is stopped and under the PU operation mode. To enable the parameter setting change while the inverter is running or under the operation mode other than PU operation mode, change the Pr.77 setting.

Overview of the error messages

If a protective function has been activated, eliminate the cause of the error and then reset the frequency inverter. It is imperative that you follow the procedure in the instruction manual for the FR-CS80 frequency inverter. You can reset the frequency inverter by pressing the STOP/RESET button on the operation panel (only after a serious error), by switching the power supply off and on again, or by switching the RES signal.
