2.
Start the drive and make sure maximum speed can be obtained, and that the armature
voltage does not exceed the nameplate armature voltage
4.10 Increase current limit to rated value
1. Return the Current
Limit to 150%.
2. Save the parameters (section 3.1.2).
4.11 Set up field weakening
When using either tachometer or encoder feedback, field weakening may be enabled for a motor
which supports an extended speed range.
1. Stop the drive and enable
the field weakening mode.
2. Set the minimum field current % to just less than the minimum field current % expected.
Min Field % = (Ifm + Ifb) x 90
3. Gradually increase the motor speed to maximum, taking care not to exceed the rated
armature voltage or maximum speed value noted on the motor nameplate.
4. Save the parameters (section 3.1.2).
The PL/X Digital DC Drive is now successfully commissioned.
