1.3.12 Safe enable switch
1.3.12.1 Description
Enable Switch / ES
The drive can be traversed in special operation using an enable switch (see operation mode
selector).
1.3.12.2 Conditions
A safe input must be parameterised and interconnected as enable switch. You can only
connect and parameterise one enable switch. The ES bit of the safety bus must be
deactivated (C15113).
The enable switch function can also be selected via the safety bus with the ES bit, unless
a safe input is parameterised as enable switch.
The special operation must be activated.
The plausibility check rejects ambiguous settings until they are parameterised correctly.

1.3.12.3 Activation
How to activate the function:
ƒ Via a safe input which has been assigned to the function by parameterisation. With
the edge change 0−1 of the ES signal, the status changes to "Acceptance (ES)".
Only if no safe input is used, the function can only be activated via the safety bus:
ƒ A data telegram with corresponding contents must be transmitted to the standard
device (edge change 0−1 of the ES signal).
