Description: Sets the signal source to activate the essential service mode (ESM) via digital input.
Using this function, when required the motor can be operated for as long as possible (e.g. to extract smoke).
BI: p3880 = 1 signal:
The essential service mode is activated.
BI: p3880 = 0 signal:
The essential service mode is deactivated.
Dependency: See also: p3881, p3882, p3883, p3884, r3889
WARNING
When activating the essential service mode (BI: p3880 = 1 signal), the motor immediately runs according to the
selected setpoint source. When the essential service mode is activated, the motor cannot be stopped using the OFF
commands.
Note
ESM: Essential Service Mode
Permissible signal sources:
- BO: r0722.x (high active)
- BO: r0723.x (low active), x = 0 ... 5, 11, 12
