Function
With this additional connection, the digital input DI4 shows if any of the MOVIMOT
®
in-
verters is ready for operation.
•
DI4 = 0 => No MOVIMOT
®
inverter is ready for operation (e.g. 24V_P is missing).
•
DI4 = 1 => At least 1 MOVIMOT
®
inverter is ready for operation.
The feedback of the maintenance switch and the STO (Safe Torque Off) safety func-
tion of the MOVIMOT
®
drives are possible.
5 digital inputs (DI0 – DI3 and DI5) are available.
