THROT FAULT LO
The
throttle fault low
parameter sets the lower throttle fault threshold; throttle
input voltages below this threshold will signal a throttle fault.
THROT FAULT HI
The
throttle fault high
parameter sets the upper throttle fault threshold; throttle
input voltages above this threshold will signal a throttle fault.
3 — PROGRAMMABLE PARAMETERS: Current Limit Parameters
Current Limit Parameters
M1/M2 MAIN C/L
The
main current limit
parameter allows adjustment of the maximum current
the controller will supply to the motor during drive operation. This parameter
can be used to reduce the maximum torque applied to the drive system by the
motor in either of the modes. The drive current limit is adjustable from 100
amps up to the controller’s full rated current. The full rated current depends
on the controller model.
REGEN C/L
The
regenerative current limit
parameter allows adjustment of the maximum
current the controller will supply to the motor during regen braking opera-
tion. During regen braking, this parameter controls the regen current from the
motor’s armature into the battery. The braking current limit is adjustable from
0 amps up to the controller’s full rated current. The full rated current depends
on the controller model.
Regen is the normal mode of braking.
PLUG C/L
The
plug current limit
parameter allows adjustment of the maximum current
the controller will supply to the motor during plug braking operation. During
plug braking, this parameter controls the plug current from the motor’s armature.
The plug current limit is adjustable from 0 amps up to the controller’s full rated
current. The full rated current depends on the controller model.
Plug braking is used during WalkAway
™
and Anti-Rollback operation.
WALKAWAY C/L
The
WalkAway current limit
parameter sets the maximum field current
applied during WalkAway
™
operation. The WalkAway
™
function applies field
current to slow a vehicle that is detected as moving while the main contactor
is open. The motor force created from this function is intended to limit the
vehicle’s rolling speed, but may not be sufficient to slow heavy vehicles on steep
