Step 4: Remaining Motor parameters
4.1 Typical Max Speed. Set the motor’s typical maximum speed as per the application’s
requirements. is value does not need to be set precisely, an estimate will do. All the vehicle
response rates are normalized to the Typical Max Speed parameter.
See Programmer » Motor Setup » Typical Max Speed
4.2 Swap Motor Direction. is parameter will be adjusted, as needed, when the motor is driven.
It swaps the mechanical direction of the motor rotation. If forward throttle produces reverse
direction, change this parameter. is parameter is critical for the emergency reverse to work
properly. Note that the encoder also has the phasing order parameter.
See Programmer » Motor Setup » Swap Motor Direction
4.3 Limited Operating Strategy. Limited Operating Strategy (LOS) is for driving the vehicle back
to a repair center at very low speeds in the event the motor encoder fails. When programmed
O, in the event of an encoder fault, the encoder fault remains and drive is disabled (i.e., the
vehicle cannot be driven). If the application’s LOS is known, set these parameters now, else
leave the default values (LOS is enabled) and adjust these parameters as needed during motor
or vehicle tuning.
See Programmer » Motor Setup » Induction Motor » Limited Operating Strategy » menu
4.4 Field Weakening. is applies only to ACIM. Regardless of whether an existing motor-type or
the auto-characterization method is used, all applications will need to run the Field Weakening
Base Speed test. Adjust these parameters, in the tuning section, or the auto-characterization
procedure as applicable.
See Programmer » Motor Setup » Induction Motor » Field Weakening » menu
4.5 Characterization Tests. e parameters and monitor items in this menu are only applicable
when conducting the auto-characterization procedure. See the traction motor procedures, below.
Controller Setup Guide
Step 5: Current Limits
e Drive, Regen, Brake, EMR, and Interlock Current Limit parameters are a percentage of the
controller’s full rated current. e controller’s full rated current is on the label of the controller.
Set the current limit parameters to your application’s objectives, or wait until tuning the motor
and/or vehicle.
See Programmer » Controller Setup » Current Limits » menu
Step 6: External Supplies
If the encoder’s supply was not set in Step 3, set it up in the External Supplies menu. If there are
minimum and/or maximum supply-current trip points, set these now. Otherwise, leave at their
default values (recommended).
