Enabling the “Safe standstill (SH)” function
The “Safe standstill” function is enabled via the following parameters:
S p9601.0 SH via terminals (Control Unit)
S p9801.0 SH via terminals (Motor Module)
Selecting/deselecting “Safe standstill”
The “Safe standstill” function must be selected/deselected “simultaneously” in both
monitoring channels via the input terminals. This only affects the drive in question.
1-signal: The function is deselected
0-signal: The function is selected
“Simultaneously” means:
The changeover must be complete in both monitoring channels within the parame-
terized tolerance time.
S p9650 Safety Integrated tolerance time SGE changeover (Control Unit)
S p9850 Safety Integrated tolerance time SGE changeover (Motor Module)
If the “Safe standstill” function is not selected/deselected within the tolerance time,
this is detected by the crosswise data comparison and fault F01611 or F30611
(STOP F) is output.
The following occurs when “Safe standstill” is selected:
S Each monitoring channel triggers the safe pulse disable via its shutdown path.
S A motor holding brake is applied (if connected and configured).
The following occurs when “Safe standstill” is deselected:
S Each monitoring channel cancels the safe pulse disable via its shutdown path.
S The safety prompt “Apply motor holding brake” is canceled.
Note
If the two input signals for selecting/deselecting “Safe standstill” differ momentarily
(i.e. within the tolerance time in p9650/p9850), the drive is stopped although no
message is output.
If you want a message to be displayed in this case, however, you have to
reconfigure N01620/N30620 as an alarm or fault.
