0x2A: AC Drive Object
The "AC Drive Object" describes the device-specic funcons of the inverter, e. g. speed
ramps, torque control etc.

The scaling factor can be set with 0x400B:009 (P592.09).
Example:
•
Torque setpoint (0x400B:008) = 345 [Nm]
•
Scaling factor (0x400B:009) = 3
•
Scaled torque setpoint = 345 [Nm] / 2

= 43.125 [Nm]
22 SpeedScale Not implemented. Use the value "0" for SpeedScale.
