Digital Inputs Terminals Parameter Function Active

Command source* - P0700 = 2 Terminals Yes

Digital Input 0, DI0 5 P0701 = 1 ON/OFF1 Yes

Digital Input 1, DI1 6 P0702 = 12 Reversing Yes

Digital Input 2, DI2 7 P0703 = 9 Fault acknowledge Yes

Digital Input 3, DI3 8 P0704 = 15 Fixed setpoint (direct) No

Digital Input 4, DI4 16 P0705 = 16 Fixed setpoint (direct) No

Digital Input 5, DI5 17 P0706 = 17 Fixed setpoint (direct) No

Digital Input 6, DI6 40 P0707 = 18 Fixed setpoint (direct) No

Digital Input 7, DI7 41 P0708 = 0 Digital input disabled No

Digital Input 8, DI8 42 P0709 = 0 Digital input disabled No

*) With CU240S DP and CU240S DP-F control units, P0700 and P1000 are set to 6 (command

source and setpoint source via PROFIBUS-DP).

If all the installation and commissioning requirements are met and the motor data matches

the inverter data, the following is possible with the factory settings, when using a control unit

CU240S:

To start and stop the motor Using DI0 with external switch

To reverse direction of rotation Using DI1 with external switch

To reset faults Using DI2 with external switch

To enter a frequency setpoint Using AI0 with external potentiometer;

the default setting of the AI: Voltage input

To display the actual frequency value Using AO0 as current output

The potentiometer and the external switches can be connected through the inverter internal

power supply, as shown in section "Connecting the Control Unit via terminals".

Notice

If settings have to be made which go beyond the factory settings, then depending on the

complexity of the application, when commissioning the inverter, the particular function

description as well as the parameter list including function charts must be carefully taken into

consideration.
