3 — PROGRAMMABLE PARAMETERS
35% PWM output at half throttle (halfway between 10% and 60%). The 30%
ramp shape gives 25% PWM at half throttle (30% of the range {which is 50%,
from 10% to 60%}, starting at 10% output, or {[.30 × 50%] + 10%} = 25%).
M1 MAIN C/L [default access: OEM]
M2 MAIN C/L [default access: OEM]
The main current limit parameter allows adjustment of the maximum current
the controller will supply to the motor during both drive and regen operation.
This parameter can be limited to protect the motor from excessive (potentially
damaging) currents or to reduce the maximum torque applied to the drive system
by the motor. It is adjustable from 50% to 100% of the rated maximum controller
current.
EMR REV C/L [default access: OEM] (123X models only)
The emergency reverse current limit parameter defines the controller’s current
limit, regardless of the selected mode, when the belly button input (Pin 10) is
active. The emergency reverse current limit is adjustable from 0% to the full rated
controller current, regardless of the M1 and M2 main current limit settings. NOTE:
If the controller is not factory-configured for the emergency reverse option, this
parameter will not be displayed in the Program Menu.
CALIBRATION 5 [default access: OEM]
The regen current boost parameter allows the regenerative braking current limit
to be set higher than the main current limit. This feature can provide higher
braking torque to stop heavy vehicles on steep inclines. The regen current boost
parameter is adjustable from 0–25% above the programmed main current limit.
