Ci: Moment Of Inertia Scaling Signal Source / M_Inert Scal S_Src; Load Moment Of Inertia / Load M_Inertia; Accelerating For Torque Control Scaling / A For M_Ctrl Scal; Macro Connector Inputs (Ci) For Torque Setpoints / Macro Ci M_Set - Siemens SINAMICS G150 Manual

Warning: The acceleration precontrol r1518 is kept at the old value if the ramp-function generator tracking (r1199.5) is active or
the ramp-function generator output is set (r1199.3). This is used to avoid torque peaks. Depending on the application,
it may therefore be necessary to disable the ramp-function generator tracking (p1145 = 0) or the acceleration
precontrol (p1496 = 0).
The acceleration precontrol is set to zero, if the Vdc control is active (r0056.14/15).
Note: The parameter is set to 100% by the rotating measurement (refer to p1960).
The acceleration pre-control may not be used if the speed setpoint manifests significant ripple (e.g. analog setpoint)
and the rounding-off in the speed ramp-function generator is disabled.
We also recommend that the pre-control mode is not used if there is gearbox backlash.

Macro Connector Inputs (CI) for torque setpoints / Macro CI M_set

VECTOR_G Can be changed: C2(1), T
Data type: Unsigned32
P-Group: Commands
Not for motor type: REL
Min
0
Description: Runs the corresponding macro files.
The Connector Inputs (CI) for the torque setpoints of the appropriate Command Data Set (CDS) are appropriately
interconnected.
The selected macro file must be available on the memory card/device memory.
Example:
p1500 = 6 --> the macro file PM000006.ACX is run.
Dependency: Refer to: p0015, p0700, p1000, r8573
