PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Position Sensor Type
Feedback_Type
0x3520 0x00
Enumeration
1 – 2
Sin/Cos Set this parameter to the type of position feedback device in
your vehicle:
1 = quadrature encoder
2 = sin/cos encoder
3 = internal steering
4 = Hall switch
5 = PMDC open-loop/sensorless (contact Curtis).
Note: A Parameter Mismatch Fault will result unless the Position
Sensor Type matches the Motor Technology setting as follows:
If Motor Technology = 0 (ACIM) then Position Sensor Type must =
1 (quadrature encoder) or 2 (sin/cos encoder).
If Motor Technology = 1 (PMAC) Position Sensor Type must =
2 (sin/cos encoder) or = 4 (Hall switch).
Enable Multiturn Sensor
Feedback_Multiturn
0x306D 0x00
0 – 1
0 – 1
0
[PCF]
Enable Multiturn Sensor = 0 (Off): One sensor cycle per
mechanical revolution. (Not using a multiturn encoder).
Enable Multiturn Sensor = 1 (On): One sensor cycle per electrical
cycle. (Using a multiturn encoder).
Test Enable
PMAC_Commissioning_Test_
Enable
0x3288 0x00
Off – On
0 – 1
Off This parameter is used to start the PMAC motor
commissioning procedure.
Test Throttle
PMAC_Test_Throttle
0x3291 0x00
–1 – 1
–1 – 1
0 Begins characterization if a Test Enable is asserted.
IMPORTANT: If the motor starts to turn in the positive (forward)
vehicle speed direction, set the Test Throttle to 1. If it turns in the
negative (reverse) direction, set the Test Throttle to -1.
Max Test Current
PMAC_Commissioning_Max_
Test_Current
0x3286 0x00
2 – 40 %
655 – 13108
20 % This parameter is used to set the maximum motor current
allowed during PMAC motor commissioning.
CR Tune Max Current
CR_Tune_Max_Current
0x328B 0x00
10 – 100 %
102 – 1024
100 % Sets the maximum current regulator routine’s current (percent).
Current Reg Autotune Bypass
PMAC_CR_AutoTuneBypass
0x328A 0x00
0 – 1
0 – 1
0 Bypasses the CR autotune during motor characterization. This
should only be done if the autotuning isn't working correctly
for a particular motor. In that case the CR gains need to be
determined manually.

PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Kemf (LL) Vrms/krpm
Kemf_LL_Vrms_krpm
0x3665 0X00
0.00 – 100.00
0 – 10000
4.50
[PCF]
The back EMF of the motor expressed as Vrms line to line
at 1000RPM.
PCF if motor control active.
