Return to TOC Curtis AC F4-A Motor Controller – August 2020
APPLICATION SETUP — EM BRAKE CONTROL MENU, cont’d
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) across keyswitch cycles. If 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 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such that the torque measured by position-hold is no longer valid.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 — EMERGENCY REVERSE (EMR) MENU
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
EMR Enable
EMR_Enable
0x3495 0x00
On/Off
On/Off
Off Enables or disables the Emergency Reverse function.
On = emergency reverse is enabled.
Off = emergency reverse is disabled.
EMR State
EMR_State
0x3490 0x00
On/Off
On/Off
Read Only Emergency reverse input is On or Off, from the selected source
(Programmer IO Assignments » Controls menu).
EMR Forward Lock
Forward_EMR_Lock
0x349B 0x00
On/Off
On/Off
Off Only allows EMR to operate if the vehicle is moving forward.
EMR Dir Interlock
EMR_Dir_Interlock
0x3494 0x00
On/Off
On/Off
Off Determines whether the cycling of the interlock switch is
required following an emergency reverse event before driving
the vehicle, again.
On = Interlock and throttle and direction must all be cleared
(cycled).
Off = Only throttle and direction must be cleared (cycled).
EMR Time Limit
EMR_Time_Limit_mSec
0x3497 0x00
0.0 – 30.0 s
0 – 30000
3.0 sec Denes how long emergency reverse is active after the vehicle
is moving in the reverse direction. This timer will restart if the
vehicle ever goes forward while emergency reverse is still active.
The allowable range is 0-30 seconds where 30 seconds is a
special case of no time out.
When emergency reverse times out the Emer Rev Timeout fault is
set. Cycling the emergency reverse input will clear the Emer Rev
Timeout fault.
To stop the vehicle after an EMR event (not move in reverse
direction) set this parameter to 0.
EMR Speed
EMR_Speed
0x3496 0x00
50 – 6000 rpm
50 – 6000
1000 rpm Denes the maximum reverse speed of the motor (in motor rpm)
when emergency reverse is active.
EMR Accel Rate
EMR_Accel_Rate
0x3492 0x00
0.1 – 3.0 s
100 – 3000
0.1 sec Sets the rate (seconds/Typical Max Speed) at which the vehicle
accelerates in the opposite direction after being brought to a stop. If
the vehicle is already traveling in the reverse direction below the EMR
Speed, the EMR Accel Rate will bring the vehicle to the EMR Speed.
EMR Decel Rate
EMR_Decel_Rate
0x3493 0x00
0.1 – 3.0 s
100 – 3000
0.1 sec Sets the rate (in seconds/Typical Max Speed) at which the vehicle
brakes to a stop when activating the emergency reverse while the
vehicle is moving forward. If the vehicle is already traveling in the
reverse direction above the EMR Speed. the EMR Decel Rate will
bring the vehicle down to the EMR Speed.
