Siemens SINAMICS G120XA - BI: ESM Direction of Rotation Signal Source; ESM Rot dir S S; ESM Setpoint Source Alternative; ESM Setp_Src Alt

WARNING
For p3881 = 4:
If the technology controller is used as setpoint source, then this must first be configured. p2251 must be set to 0.
Note
ESM: Essential Service Mode
When the essential service mode is activated, the effective speed setpoint is displayed in r1114.
For p3881 = 0:
The last known setpoint value is only transmitted safely if it was present consistently for at least 30 s prior to activating
the essential service mode. If this condition is not met, fixed speed setpoint 15 (p1015) is used.
For p3881 = 6:
n_act = 0: pulse suppression and switching on inhibited.
n_active > 0: braking along the ramp-function generator down ramp (p1121), pulse cancellation and switching on
inhibited.
For p3881 = 7:
n_act = 0: pulse suppression and switching on inhibited.
n_act > 0: immediate pulse cancellation and switching on inhibited.

Description: Sets the alternative setpoint source for essential service mode (ESM).
This setpoint is used when the setpoint source set in p3881 is lost.
Value: 0: Last known setpoint (r1078 smoothed)
1: Fixed speed setpoint 15 (p1015)
2: Maximum speed (p1082)
Dependency: See also: p3881
Note
ESM: Essential Service Mode
The alternative setpoint source is only active for p3881 = 2, 3, 4.

Description: Sets the signal source for the direction of rotation during essential service mode (ESM).
p3883 = 1 signal:
Direction of rotation of the setpoint, parameterized for essential service mode, is reversed.
p3883 = 0 signal:
Direction of rotation of the setpoint parameterized for essential service mode is kept.
WARNING
The direction reversal is not taken into account if p3881 = 4 is set (technology controller) and the technology controller
is also active as the setpoint source.
