SINAMICS G120 CU230P-2 Control Units
320 List Manual (LH9), 04/2014, A5E33838102B AA
Value: 0: Last known setpoint (r1078 smoothed)
1: Fixed speed setpoint 15 (p1015)
2: Control Unit analog input 0 (AI 0, r0755[0])
3: Fieldbus
4: Techn controller
6: Enable the response OFF1
7: Enable the response OFF2
Warning: Re 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.
Re 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.
Re p3881 = 6:
n_act = 0: pulse cancellation and switching-on inhibited.
n_active > 0: braking along the ramp-function generator down ramp (p1121), pulse cancellation and switching-on
inhibited.
Re p3881 = 7:
n_act = 0: pulse cancellation 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: Refer to: 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.
Note: ESM: Essential Service Mode
