If the terminal is not evaluated, and the response that makes sense for this
particular case is initiated in the machine control system, then this can destroy
the system, converter or motor!

Input current, enable circuits:
Terminals 48, 63, 64, and 65: Input current, optocoupler approx. 12 mA at +24 V
Terminal 663: Input current, optocoupler and start inhibit relay approx. 30 mA at
+24 V
When selecting the switching devices and the auxiliary contact on the main
switch, the contact reliability when switching low currents must be carefully
taken into consideration.
Switching capacity of the signaling contacts:
The max. switching power of the signaling contacts is specified in the interface
overviews of the modules in Chapters 4 and 6, and must be absolutely com-
plied with!
