M1/M2 MIN SPD
The
minimum speed
parameter defines the maximum allowed speed at full
forward throttle with the speed limit pot in its minimum speed position. For
example, if Mode 1 Minimum Speed is set at 20% and the speed limit pot is
in its minimum speed position, the controller will adjust its output to achieve
20% speed at full throttle in Mode 1. The minimum speed cannot be set higher
than the programmed maximum speed. Note: If a speed limit pot is not used
in your application, see page 12.
M1/M2 REV MAX SPD
The
maximum reverse speed
parameter defines the maximum allowed speed
in reverse at full throttle with the speed limit pot in its maximum speed posi-
tion. For example, if Mode 1 Maximum Reverse Speed is set at 40% and the
speed limit pot is in its maximum speed position, the controller will adjust
its output to achieve 40% reverse speed at full throttle in Mode 1. Note: If a
speed limit pot is not used in your application, see page 12.
REV MIN SPD
The
minimum reverse speed
parameter defines the maximum allowed speed in
reverse at full throttle with the speed limit pot in its minimum speed position.
Reverse speed is not affected by which mode (Mode 1, Mode 2) is selected.
Note: If a speed limit pot is not used in your application, see page 12.
CREEP SPD
Creep speed
helps to prevent vehicle rollback on inclines when the brake is
released with very little throttle applied. It is activated when the throttle request
exceeds the throttle’s deadband threshold. The throttle response is rescaled so
that the controller’s output is adjustable over the full throttle range, but starting
at the programmed creep speed value. Creep speed is programmable from 0%
to 10.0% of the maximum available speed.
PUSH SPD
When the push switch is switched to the On position, the push feature releases
the electromagnetic brake and allows the vehicle to be manually pushed. The
maximum speed at which the vehicle can be pushed is defined by the
push
speed
parameter. It is programmable from 25% to 50% of the maximum
available speed. This parameter also sets the “push-too-fast” speed, which is the
maximum speed at which the vehicle can be pushed when it is unpowered and
the brake is mechanically released. Note: the vehicle must be manually pushed
fast enough so that the motor voltage reaches approximately 15 V in order for
the push feature to be activated.
