Speed Controller Parameters
0 – SPEED MODE EXPRESS
ALLOWABLE
RANGE
100 – 8000 rpm Defines the maximum requested motor rpm at full throttle. Partially-
applied throttle is scaled proportionately; e.g., 40% applied throttle
100 – 8000
corresponds to a request for 40% of the set Max Speed Value.
Note: The maximum motor rpm is subject to the constraints on page 29.
0 – 100 % Determines how aggressively the speed controller attempts to match
the speed of the motor to the commanded speed. Larger values provide
0 – 8192
tighter control.
If the gain is set too high, you may experience oscillations as the
controller tries to control speed. If it is set too low, the motor may behave
sluggishly and be difficult to control.
5 – 100 % The integral term (Ki) forces zero steady state error, so the motor
will run at exactly the commanded speed. Larger values provide tighter
50 – 1000
control.
If the gain is set too high, you may experience oscillations as the
controller tries to control speed. If it is set too low, the motor may take
a long time to approach the exact commanded speed.
0.1 – 30.0 s Sets the rate (in seconds) at which the speed command increases
when throttle is applied. Larger values represent slower response.
100 – 30000
0.1 – 30.0 s Sets the rate (in seconds) that is used to slow down the vehicle when
the throttle is reduced. Larger values represent slower response.
100 – 30000
0.1 – 30.0 s Sets the rate (in seconds) at which the vehicle slows down when brake
is applied or when throttle is applied in the opposite direction. Larger
100 – 30000
values represent slower response.
On / Off This parameter should be programmed On to operate a pump motor
rather than a vehicle drive motor. Speed controller responsiveness and
On / Off
stability are enhanced.
On / Off This parameter works together with Pump Enable as follows.
When Pump Enable = On and Regen Lower Enable = On, the pump
On / Off
motor can turn in both the forward and the reverse direction. In this case,
the pump can be used as the Lower function (reverse).
When Pump Enable = On and Regen Lower Enable = Off, the pump
motor can turn only in the forward direction. In this case, a hydraulic valve
is typically used for the Lower function.
When Pump Enable = Off, the Regen Lower Enable parameter
has no effect on the control system.
