VARIABLE DISPLAY RANGE DESCRIPTION
BDI
BDI_Percentage
0x3308 0x00
0 – 100%
0 – 100
Lead-acid battery discharge indicator (BDI). Effectively the battery’s
remaining state-of-charge.
NOTE: For non lead-acid batteries, including Lithium-Ion battery packs, use
the pack’s or cell manufacturer’s approved Battery Management System
(BMS) for determining the BDI.
Capacitor Voltage
Capacitor_Voltage
0x324C 0x00
0.0 – 200.0 V
0 – 12800
Voltage of controller’s internal capacitor bank at B+ terminal.
Keyswitch Voltage
Keyswitch_Voltage
0x324D 0x00
0.0 – 105.0 V
0 – 10500
Voltage at KSI (pin 1).
Insulation Resistance
Insulation_Res _kOhmsx10
0x3871 0x00
0.0 – 999.9 kΩ
0 – 9999
Insulation resistance between high power and vehicle chassis. Review the
Isolation Monitor in Chapter 3, and its set up in Chapter 7.
A value of 999.9 kW indicates inactive circuit.
A value of 999.0 kW indicates active circuit, with the insulation resistance
at the highest value that can be measured.
A value of 0 kW indicates a hard short circuit.

VARIABLE DISPLAY RANGE DESCRIPTION
Motor RPM
Motor_RPM_Display
–12000 – 12000 rpm
–12000 – 12000
Motor speed in revolutions per minute.
Filtered for display on the 1313/1314. No CAN Index is assigned to this
monitor variable. Possible usage for a tachometer, due to the ltered
(smoothing) nature of this VCL variable over the Motor_RPM variable (see
Motor RPM in monitor Controller » Motor Tuning » Motor_RPM).
Max Speed Controller Limit
Max_Speed_Controller_Limit
0x3559 0x00
0 – 12000 rpm
0 – 12000
Displays the maximum allowed speed, which clamps the upper limit of the
Max Speed parameters. It is the least of the three motor-speed constraints
described in Chapter 3.
Temperature
Motor_Temperature
0x3559 0x00
–100 – 300°C
–1000 – 3000
Temperature sensor readout.
MotorSpeed A
MotorspeedA
0x35D1 0x00
–12000 – 12000 rpm
–12000 – 12000
Motor encoder phase A speed in revolutions per minute. This can be used
to verify that phase A of the encoder is operating correctly. MotorSpeed
A should equal MotorSpeed B in a properly operating motor encoder.
MotorSpeed A does not indicate direction.
MotorSpeed B
MotorspeedB
0x35D2 0x00
–12000 – 12000 rpm
–12000 – 12000
Motor encoder phase A speed in revolutions per minute. This can be used
to verify that phase B of the encoder is operating correctly. MotorSpeed B
should equal MotorSpeed A in a properly operating motor encoder.
MotorSpeed B does not indicate direction.
Sin Input A
encoder_sin_calibrated
0x38C5 0x00
–1023 – 1023
–1023 – 1023
Input at Position Feedback A (pin 31).
This parameter has scaling changes and a variable name change.
Cos Input A
encoder_cos_calibrated
0x38C6 0x00
–1023 – 1023
–1023 – 1023
Input at Position Feedback B (pin 32).
This parameter has scaling changes and a variable name change.
Rotor Position
rotor_position_raw
0x38C7 0x00
–32768 – 32767
–32768 – 32767
The displayed value will never exceed 4095. 0 – 4095 maps to mechanical
0°– 360°.
