Indicates the value of P208 x P005.
When the vector control mode is used (P202=2), P002 indicates
the actual motor speed in rpm.
In case of different scales and units, use P208.
Indicates the inverter output current in Amps. (A).
Indicates the inverter DC Link voltage in Volts (V).

Indicates the torque developed by motor in, in percent (%) relating
to the set rated motor torque.
The rated motor torque is defined by the parameters P402
(motor speed) and P404 (motor power). I.e.:
where T
nom
is given in kgf.m, P
nom
is the rated motor power in watts-
HP - (P404), and n
