Function
With this additional connection, the field distributor delivers the status of the mainten-
ance switch to the higher-level controller.
•
Maintenance switch on => digital input DI0 = 1.
•
Maintenance switch off => digital input DI0 = 0.
The STO (Safe Torque Off) safety function of the MOVIMOT
®
drives is possible.
Depending on the configuration, the following is available:
