Unidrive M200/201 Control Quick Start Guide
Issue Number: 3
Open loop mode:
The
Output Frequency
is the sum of the
Post Ramp Reference
and the motor slip compensation
frequency.
RFC-A mode:
The output frequency is not controlled directly, but the
Output Frequency
is a measurement of the
frequency applied to the motor.
The
Output Voltage
is the rms line to line voltage at the AC terminals of the drive.
Motor Rpm
= 60 x Frequency / Pole pairs
where
Pole pairs = the numeric value of
Number Of Motor Poles
(Pr
40
) (i.e. 3 for a 6 pole motor)
The frequency used to derive the
Motor Rpm
is the
Final Demand Reference
(Pr
83
).
Current Magnitude
is the instantaneous drive output current scaled so that it represents the r.m.s.
phase current in Amps under steady state conditions.
Torque Producing Current
is the instantaneous level of torque producing current scaled so that it
represents the r.m.s. level of torque producing current under steady state conditions.
