Bi: Droop Feedback Enable / Droop Enable; Co: Moment Of Inertia Total, Scaled / M_Mom Inert Tot_Sc; Ci: Acceleration Pre-Control / A_Prectrl; Acceleration Pre-Control Scaling / A_Prectrl Scal - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
p1492[0...n]

BI: Droop feedback enable / Droop enable

VECTOR_G (n/M) Can be changed: U, T
Data type: Unsigned32 / Binary
P-Group: Closed-loop control
Not for motor type: REL
Min
-
Description: Enables the droop to be applied to the speed/velocity setpoint.
Dependency: Refer to: p1486, p1487, p1488, p1489, r1490
Note: Even when not enabled, the droop speed is calculated but not subtracted from the setpoint speed. This makes it
possible to subtract the result of this calculation from the speed of another drive.
r1493

CO: Moment of inertia total, scaled / M_mom inert tot_sc

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [kgm²]
Description: Display and connector output for the parameterized total moment of inertia.
The value is calculated with ((p0341 * p0342) * p1496).
The scaling is not take into account using p1497.
p1495[0...n]

CI: Acceleration pre-control / a_prectrl

VECTOR_G (n/M) Can be changed: T
Data type: Unsigned32 / FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
-
Description: Sets the signal source for the acceleration pre-control.
Dependency: The signal source for the acceleration is activated with p1400.2 = 1.
For p1400.2 = 0, the acceleration pre-control is calculated from the speed setpoint change from r0062.
For p1400.2 = 0 and activate reference model (p1400.3 = 1) the acceleration pre-control is switched out.
Refer to: p1400, p1496
Note: If the acceleration is entered as external signal, then the accelerating torque is calculated as follows (r1518):
r1518 = acceleration (% of p2007) / 100 % * (p2007 * 60 s) / p0311 * r0345 / 1 s * r0333
p1496[0...n]

Acceleration pre-control scaling / a_prectrl scal

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.0 [%]
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency: When the reference model is activated (p1400.3 = 1) and for an internal acceleration pre-control (p1400.2 = 0), the
acceleration pre-control is switched out (disabled). The reference model (p1400.3 = 1) and external acceleration pre-
control (p1400.2 = 1) can be operated together.
Refer to: p0341, p0342
