[SPEED MODE & SPEED MODE EXPRESS only]
ALLOWABLE
PARAMETER
RANGE
DESCRIPTION
EMR Enable
On/Off
Determines whether the emergency reverse function is active.
EMR_Enable
On/Off
On = emergency reverse is enabled.
OptionBits1 [Bit 1]
Off = emergency reverse is disabled.
EMR Type
0–1
Determines where the input comes from for emergency reverse.
EMR_Type
0–1
0 = emergency reverse activated by switch 1 (pin 24).
1 = emergency reverse is activated by VCL functions
Enable_Emer_Rev() and Disable_Emer_Rev().
EMR Dir Interlock
On/Off
Determines whether the interlock switch must be turned off after emergency
EMR_Dir_Interlock
On/Off
reverse before the vehicle can be driven again.
EMR_Dir_Interlock_Bit0 [Bit 0]
On = Interlock and throttle and direction must all be cleared.
Off = Only throttle and direction must be cleared.
EMR Time Limit
0–30 sec
Defines how long emergency reverse is allowed to be active after the vehicle
EMR_Time_Limit
0–3750
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
50–6000 rpm
Defines the maximum reverse speed of the motor (in motor rpm), when
EMR_Speed
50–6000
emergency reverse is active.
EMR Accel Rate
0.1–3.0 sec
Sets the rate (in seconds) at which the vehicle accelerates in the opposite
EMR_Accel_Rate
100–3000
direction after it has been 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
0.1–3.0 sec
Sets the rate (in seconds) at which the vehicle brakes to a stop when
EMR_Decel_Rate
100–3000
emergency reverse is activated and 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.
