4.4 Automatic restart after mains connection/trouble...
.../Fault/"Safe torque off active"
In
C00142 , the starting performance of the controller after mains connection and reset of "Trouble",
"Fault", or "Safe torque off active" can be parameterised.
Auto-start option 0: Auto restart inhibited after mains connection
Controller inhibit always has to be set if the controller is to change from the "Ready to switch on"
state to the "Switched on" state after mains connection or reset of "Trouble", "Fault", or "Safe torque
off active". The following change to the "Operation" state is performed when the controller is
enabled:
[4-25] State change when auto-restart is inhibited (C00142 = "0: Inhibited")

Danger!
If automatic restart is enabled ( C00142 = "1: Enabled"), the drive can restart
automatically from the "Trouble" and "Safe torque off" device states when the trouble or
request for "Safe torque off active" has been eliminated!

Note!
From software version V4.0 the automatic restart is inhibited in the Lenze setting! Set
the selection "1: Enabled" in C00142 to obtain the former behaviour.
