Motor Temperature Cutback
MotorTempCutback
0x3439 0x00
0 – 100 %
0 – 4096
Displays the current available as a result of the motor temperature cutback
function. A value of 100% indicates no cutback in current.
Controller Temperature Cutback
ControllerTempCutback
0x3437 0x00
0 – 100 %
0 – 4096
Displays the current available as a result of the controller temperature
cutback function. A value of 100% indicates no cutback in current.
Undervoltage Cutback
UnderVoltageCutback
0x343B 0x00
0 – 100 %
0 – 4096
Displays the current available as a result of the undervoltage cutback
function. A value of 100% indicates no cutback in current. Does only limit
drive current, but does not affect regen current limit.
Overvoltage Cutback
OverVoltageCutback
0x343A 0x00
0 – 100 %
0 – 4096
Displays the current available as a result of the overvoltage cutback
function. A value of 100% indicates no cutback in current. Does only limit
regen current, but does not affect drive current limit.
LF Cutback
LF_Cutback
0x4F5C 0x00
0 – 100 %
0 – 4096
Displays the current available as a result of the low motor speed
(electrical-frequency) cutback function.
A value of 100% indicates no cutback in current.
Battery Current Cutback
BatteryCurrentCutback
0x3C05 0x00
0.0 – 100.0 %

–50 – 200°C
– 50 – 200
Traction FET Junction Temperature at which the controller begins cutting
back current.
Traction FET Max Temp High
FET_Max_Temp_High
0x4F8E
–50 – 200°C
– 50 – 200
Traction FET Junction Temperature at which the controller allows zero current.
* Note that the displayed Pump FET Temp variables do not apply to the non-pump controllers.
