3d. motor data tabulation
Before commissioning, it is recommended to record the actual motor nameplate data. Also record gearbox, and
attached roll diameter, or any appropriate mechanical data that may be needed during setup.
This table may be used as a guide to record motor nameplate and application data

Nameplate dual speed rating
The value for RPM may be represented with two values, the first representing base speed , which is the rpm at
nameplate volts and nameplate field current.
A second RPM value, if shown, corresponds to rated top speed, which is achieved at rated nameplate volts, and
a weak field setting. The weak field setting would correspond to the second value of field amps.
For the nameplate below, base speed is 1750 rpm @ 3 amps field and top speed is 2300 rpm @ 1 amp field

Verify the motor data matches the drive power rating, output voltages, and required motor speed is achievable.
