Unimotor fm Servo Motors - E2/U2 migration to E3/U3 models
Motor Parameters
Higher Torque ratings
The Cross Reference Table (page 3), shows in some cases that the stall torque of the E3/U3 models has increased. Although
this higher performance is available, it is not available to the application unless the servo drive has a sufficient current
rating and the appropriate drive parameters are set to the new motor data. Keep in mind that if the previous E2/U2 motor
was providing the required torque there is no need to change the existing drive settings, the new E3/U3 motor and existing
drive will provide the equivalent performance.
If the higher rating is needed use the motor name plate data to determine the information to enter for the new motor
parameters.
Use the following three steps to update the drives motor map information.
1. Use the appropriate commissioning software and update the motor information as indicated on the motor nameplate.
2. Verify that the motor feedback device settings in the drive match the motors feedback device.
3. Perform a rotating Autotune de-coupled from the load as described in the appropriate drive product literature.
4. Save the new drive parameters.
