PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Save Torque Preload
Save_Torque_Preload
0x3474 0x00
On/Off
On/Off
Off Enabling this parameter will save the Torque Preload
(HillHoldMemory, 0x347C) across keyswitch cycles. If EM_Brake_
Torque_Preload_Cancel_Delay is nonzero and this parameter
= On, the timer starts again upon startup (KSI cycle) such that
the countdown is from the full value of the EM_Brake_Torque_
Preload_Cancel_Delay parameter.
Torque Preload Cancel Delay
EM_Brake_Torque_Preload_
Cancel_Delay
0x3476 0x00
0 – 120 s
0 – 15000
0 sec The timer starts after the EM brake is set. If the timer expires
before the throttle is re-engaged, the torque preload memory is
cleared. Setting this parameter to zero disables the timer (i.e.,
the preload is never cancelled). The purpose of this delay is to
prevent the vehicle from lunging forward if it is unloaded on a hill
such that the torque measured by position-hold is no longer valid.
Note: This parameter is applicable only when Torque Preload
Enable = On (see above).
EM Brake Fault Motor Revs
EM_Brake_Fault_Motor_Revs
0x3471 0x00
1.0 – 20.0
10 – 200
4.0 Denes the allowable number of motor revolutions after the EM
brake is set before triggering the EM BRAKE FAILED TO SET fault
(Fault Code 9-2).
APPLICATION SETUP \EM BRAKE CONTROL — EM BRAKE TEST MENU
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Mode
EM_Brake_Test_Mode
0x4F5E 0x00
Enumeration*
0 – 1
*VCL only = 0
*At Startup = 1
VCL Only Controls the test mode for the EM brake.
Direction
EM_Brake_Test_Direction
0x4F5F 0x00
Enumeration*
0 – 2
*Forward = 0
*Reverse = 1
*Both = 2
Forward Controls which direction torque is applied during the EM brake
test.
Current
EM_Brake_Test_Current
0x4F60 0x00
0 – 100 %
0 – 32767
20% The current as a percentage of base current applied during the
EM brake test.
Ramp Time
EM_Brake_Test_Current_
Ramp_Time
0x4F61 0x00
0 – 1000 ms
0 – 1000
500 ms The time taken to ramp the current to the EM_Brake_Test_
Current value. The same time is used to ramp it down again.
Test Threshold
EM_Brake_Test_Threshold
0x4F62 0x00
1.0 – 20.0 rpm
10 – 200
1.0 rpm The number of motor revolutions the motor can move during the
EM brake test before a fault is declared.
Hold Time
EM_Brake_Test_Hold_Time
0x4F63 0x00
0.0 – 1.0 sec
0 – 125
0.5 s The amount of time the torque is held between ramp up and
ramp down times.
Max Speed Limit
Max_Speed_EM_Brake_Fault
0x4F68 0x00
0 – 24000
0 – 24000
800 Set the motor rpm above which the EM Brake fault is triggered.
Hill Compensation Enable
EM_Brake_Test_Hill_
Compensation_Enable
0x4F67 0x00
0 – 1
0 – 1
0 Enables or disables modifying the torque applied during
the EM brake test while the vehicle is on a hill. If turned on,
HillHoldMemory is added to the request to avoid overstressing the
brake in 1 direction and not sufciently testing it in the other.
EM Brake Test State
EM_Brake_Test_State
0x4F66 0x00
0 – 4
0 – 4
0 The current state of the EM brake test. Can be Stop (0), Start (1),
Running (2), Done (3), or Failed (4).
