MOTOR: 1 – SPM (SURFACE PM MOTOR) CHARACTERIZATION TESTS MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Test Enable
PMAC_AutoChar_Test_Enable*
0x3862 0x00
0 – 1
0 – 1
This parameter is used to start the SPM motor characterization procedure.
See Chapter 8B for the complete description of the SPM motor
characterization procedure.
Test Throtte
PMAC_Test_Throttle*
0x30D1 0x00
–1 – 1
–1 – 1
Begins characterization if a Test Enable is asserted. This parameter is used to
change the direction of the motor to the forward direction during SPM motor
characterization.
Important: If the motor starts to turn in the positive-rpm vehicle speed
direction, set Test Throttle = 1. If it turns in the negative-rpm direction, set
Test Throttle = −1.
See Chapter 8B for the complete description of the ACIM motor
characterization procedure and how this parameter is used.
Max Test Speed
PMAC_AutoChar_Max_Test_Speed*
0x38C1 0x00
1000 – 6000 rpm
1000 – 6000
This parameter is used to set the maximum motor speed allowed during SPM
motor characterization.
See Chapter 8B for the complete description of the SPM motor
characterization procedure and how this parameter is used.
Max Test Current
PMAC_AutoChar_Max_Test_Current*
0x38C2 0x00
10 – 30%
3277 – 9831
This parameter is used to set the maximum motor speed allowed during SPM
motor characterization.
See Chapter 8B for the complete description of the SPM motor
characterization procedure and how this parameter is used.
* Note: revised variable name for os31 (i.e., the "PMAC" part of the variable name was "SPM" in os30,
and was added for "Test_Throttle"). The terms Surface Permanent Magnet (SPM) and Permanent Magnet AC
(PMAC) motors used within this manual refer to the same motor technology.
MOTOR FEEDBACK OPTIONS
PARAMETER ALLOWABLE RANGE DESCRIPTION
Feedback Type
Feedback_Type
0x382E 0x00
1 – 2
1 – 2
Set this parameter to the type of position feedback device in your vehicle:
1 = quadrature encoder
2 = Sin/Cos sensor.
NOTE: A Parameter Mismatch Fault will result unless the Feedback Type
matches the Motor Technology setting (see page 55):
If Motor Technology = 0 (ACIM), then Feedback Type must = 1 (quadrature encoder).
If Motor Technology = 1 (SPM), then Feedback Type must = 2 (Sin/Cos sensor).
Swap Feedback Direction PCF
Swap_Feedback_Direction
OptionBits3 [Bit 0]
0x306C 0x00
On / Off
On / Off
Changes the motor encoder’s effective direction of rotation. The encoder
provides data used to calculate motor position and speed. This parameter
must be set such that when the motor is turning forward, the controller
reports back a positive motor speed.
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 10 (page 83).
MOTOR FEEDBACK 1 – ENCODER MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Encoder Steps PCF
Encoder_Steps
0x304B 0x00
32 – 256
32 – 256
Sets the number of encoder pulses per revolution. This must be set to match
the encoder; see motor nameplate or its technical data for this information.
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; setting it improperly
may cause vehicle malfunction, including uncommanded drive. For
instructions, see Chapter 7, Step 8 (page 82–83).
