MOTOR: 0 – ACIM: FIELD WEAKENING CONTROL MENU, cont’d
PARAMETER ALLOWABLE RANGE DESCRIPTION
Weakening Rate Drive
Field_Weakening_Rate_Drive
0x383C 0x00
0 – 100%
0 – 500
Sets the control loop gains for eld weakening. Setting the rate too low may
create surging in the vehicle as it accelerates at mid to high speeds. Setting
the rate too high may create high frequency oscillations (usually audible)
when the vehicle accelerates at mid to high speeds.
Min Field Current
Min_Field_Current
0x3821 0x00
0 – 800 A
0 – 8000
Sets the eld current when no torque is requested from the motor. This
current pre-uxes the motor and can improve initial take-off at the expense of
some battery consumption.
MOTOR: 0 – ACIM: SWAP TWO PHASES AND MOTOR TYPE PARAMETERS
PARAMETER ALLOWABLE RANGE DESCRIPTION
Swap Two Phases PCF
Swap_Two_Phases_OptionBits3 [Bit 3]
0x306C 0x00
On / Off
On / Off
If, after Swap Encoder Direction has been set correctly, the vehicle drives
in the wrong direction (i.e., drives forward when in reverse, and vice
versa), try changing the setting of the Swap Two Phases parameter. This
parameter has the same effect as physically swapping the cables on any
two of the three motor phase connections.
Positive motor speed must be in the forward direction in order for
the emergency reverse feature to operate properly.
NOTE: Do not change this parameter while the controller is powering the
motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Adjusting this parameter can be hazardous. For instructions, see
Chapter 7, Step 12 (page 84).
Motor Type PCF
IM_Motor_Type
0x3809 0x00
0 – 324
0 – 324
This parameter references a predened table of motor parameters for
many AC induction motors. Presently, 323 motors are dened for os31.
Motor Type 0 is reserved for using the auto-characterization procedure in
Chapter 8A.
NOTE: Changing this parameter requires the re-setting of the FW
Base Speed parameter (page 56). Other parameters may also need to
be reset or evaluated by following the Initial Setup and Tuning Guide
chapters instructions.
Consult your Curtis distributor or support engineer for information how to
set this parameter based on your application and motor.
