162 [Capacitance]
Sets the DC Link capacitance. When set to non-zero, this value is used to
calculate the tuning coefficients for the voltage loop VML Ki and Kp. In the case
of a Frame 2 or Frame 3A drive, this is the capacitance inside the drive. In the
case of a Frame 3B drive, it is the capacitance in the Converter and one Inverter.
The capacitance of any additional Inverters connected to a common bus must
be entered in parameter 170 - [Bus Capacitance].
