Motor rpm can be monitored in rpm code of Drive Group.
When P46 is set to 0(V/F control) or 1(PID control), the Inverter output frequency (f) is displayed in RPM
using the formula below without Motor slip considered.
P41: Enter the number of rated motor poles on the nameplate.
P54: Enter gear ratio to monitor mechanical rotation, instead of rotation of motor axis.

Inverter DC link voltage
-
Inverter DC link of input voltage can be monitored in dCL.
2
times (1.414) the value of input voltage is displayed while motor is at a stop. This is why it is converted
to DC voltage, the maximum of AC voltage by a rectifier.
It is the voltage between P1 on the inverter’s power terminal and N terminal.
