MOTOR: CONTROL ALGORITHMS MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Motor Technology
Motor_Technology
0x3814 0x00
0 – 1
0 – 1
Set this parameter to the type of motor in your vehicle:
0 = ACIM (Induction Motor)
1 = SPM (Surface PM Motor).
NOTE: A Parameter Mismatch Fault will result unless the Feedback Type
(page 59) matches the Motor Technology setting:
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).
MOTOR: 0 – ACIM: CHARACTERIZATION TESTS MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Test Enable
IM_AutoChar_Test_Enable
0x3800 0x00
0 – 1
0 – 1
Enables ACIM (induction motor) characterization with quadrature encoder to
begin once Test Throttle is asserted.
See Chapter 8A for the complete description of the ACIM motor
characterization procedure.
Test Throtte
IM_Test_Throttle
0x3034 0x00
–1 – 1
–1 – 1
Begins ACIM characterization if the Test Enable is asserted. This parameter is
also used to change the direction of the motor to the forward direction during
ACIM 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 8A for the complete description of the ACIM motor
characterization procedure.
Motor Poles
IM_MotorData6
0x3805 0x00
2 – 8
1 – 4
This parameter is used to select the number of poles before beginning the
ACIM motor characterization procedure.
See Chapter 8A for the complete description of the ACIM motor
characterization procedure and how this parameter is used.
Max Test Speed
IM_AutoChar_Max_Test_Speed
0x38A0 0x00
500 – 8000 rpm
500 – 8000
This parameter is used to set the maximum motor speed allowed during ACIM
motor characterization.
See Chapter 8A for the complete description of the ACIM motor
characterization procedure and how this parameter is used.
Max Test Current
IM_AutoChar_Max_Test_Current
0x38A1 0x00
10 – 100%
3277 – 32767
This parameter is used to set the maximum motor current allowed during
ACIM motor characterization.
See Chapter 8A for the complete description of the ACIM motor
characterization procedure and how this parameter is used.
SlipGain
IM_MotorData8
0x3819 0x00
0.00 – 200.00
0 – 20000
This parameter is adjusted during ACIM motor characterization to tune the
motor to deliver the maximum torque per amp.
See Chapter 8A for the complete description of the ACIM motor
characterization procedure and how this parameter is used.
Current Reg Tuning Test Enable
IM_CR_Tuning_Test_Enable
0x388B 0x00
0 – 1
0 – 1
This parameter is typically applicable for previously auto-characterized
(Type 0) induction motors. It performs only the current regulation tuning
portion of the motor characterization on existing Type 0 motors (e.g., prior
to os26/30). To begin, clear any existing faults, then set the Interlock = On
and this parameter = 1. Similar to the auto-characterization routine steps in
Chapter 8A, then set Test Enable = 1 followed by setting Test Throttle = 1. The
controller will run the tuning test and issue a Parameter Change Fault when
nished.
If a new (or existing Type 0) motor is auto-characterized following the steps
in Chapter 8A, do not use this parameter, as it is automatically included in the
full auto-characterization routine.
Consult your Curtis distributor or support engineer for further assistance
based on your motor and its application.
