3.5.2.2 Enable switch (ES)
Enable Switch / ES
Description
Enable Switch / ES
This function enables overriding of the standard stop functions STO and SS1 during special
operation.

A release via the enable switch activates the parameterised motion function during special
operation and the drive can be traversed.
The stopping times assigned to the stop functions are directly deactivated/stopped.
Conditions • A safe input must be parameterised and interconnected as an enable switch. You can only
connect and parameterise one enable switch. The ES bit of the safety bus must be
deactivated ( C15113 ).
• The confirmation can also be selected via the safety bus using the ES bit unless a safe input
is set as an enable switch.
• The special operation must be activated.  Operation mode selector (OMS) ( 31)
• The plausibility check rejects ambiguous settings until you have parameterised them
correctly.
Activation How to activate the function:
• "ON state" at a safe input to which the "enable switch" function has been assigned by
parameter setting.  Safe inputs ( 42)
• Only if no safe input is used, the function can be activated via the safety bus by sending a data
telegram with a corresponding content to the controller.
