Function Diagrams And Parameters - Siemens SINUMERIK MC Commissioning Manual

Switching the motor on and off (without encoder)
The time response and diagnostic options are as follows in this SDI version:
Figure 4-22
"SDI without selection" behaves as follows when switching off and switching on again:
● After switch-off, the motor behaves in accordance with the canceled signal (OFF1, OFF2 or
OFF3).
● STO (≙ safe pulse cancellation) becomes active after the standstill limit is undershot.
● After the ON command, the converter cancels the "safe pulse suppression" state and the
start procedure is initiated.
● If the minimum current has not been reached after 5 seconds, the converter returns to the
"safe pulse suppression" state and initiates the safety message C01711(1041).
