Encoder Fault Setup. See Programmer » AC Motor Setup » Quadrature Encoder » Encoder Fault
Setup » menu.
The parameters’ default values within this menu are typically sufficient
for operation.
e Fault Detection Enable should be On.
Unless known now, the default Encoder Pulse Fault Detect Time of 0.5
seconds and Fault Stall Time of 5 seconds adjustments are re-examined
during the application’s vehicle tuning.
Step 4: Remaining AC Motor parameters
a) 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 » AC Motor Setup » Typical Max Speed.
b) Swap Two Phases. is parameter will be adjusted, as needed, when the motor is driven. If,
aer the Swap Encoder Direction parameter has been set correctly, the vehicle drives in the
wrong direction (i.e., drives forward when in reverse and vice versa) changing this parameter
will change the motor’s direction. is parameter has the same eect as physically swapping the
motor cables on any two of the three motor phase connections.
See Programmer » AC Motor Setup » Induction Motor » Swap Two Phases.
c) 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 need during motor or vehicle
tuning.
See Programmer » AC Motor Setup » Induction Motor » LOS Upon Encoder Fault
See Programmer » AC Motor Setup » Induction Motor » Limited Operating Strategy » menu
d) 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 » AC Motor Setup » Induction Motor » Field Weakening » menu
e) 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.
