2.2 List of parameters
Description: Display and connector output for the status word of the DC quantity control.
Dependency: Refer to: p3856
Description: Display and connector output for the status word of the compound braking and DC quantity control.
Dependency: Refer to: p3856
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: Refer to: p3881, p3882, p3883, p3884, r3887, p3888, 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
Description: Sets the setpoint source for essential service mode (ESM).
