There is a risk to the life and health of the user if appropriate precautionary measures are not taken. The precautions can be found in the instruction manual of the frequency inverter FR-CS80.
If you have any questions about the installation, programming and operation of the frequency inverter, please do not hesitate to contact your sales office or one of your sales partners. You can reach our technical support at the following number: +49 (0) 2102 103 7914

Power supply connection
Recommended cable gauge: 0.3 to 0.75 mm2
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 | ||
SD | 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). | |
2 | |||
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. |
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:
| |
| 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. |
Change the setting of Pr.1 Maximum frequency.

1The factory setting depends on the performance class of the frequency inverter.
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.
