TABLE 3 – TRIMPOT ADJUSTMENTS (See Section 10, on pages 25)
Trimpot Description
Forward Acceleration (FACC). Refer to Section
10.1, page 25.
Sets the amount of time for the motor to
accelerate from zero speed to full speed in the
forward direction and the time it takes to
decelerate in the reverse direction (FACC =
Reverse Deceleration). Factory adjusted to 1
second. (Maximum of 15 seconds).
Reverse Acceleration (RACC). Refer to Section
10.1, on page 25.
Sets the amount of time for the motor to
accelerate from zero speed to full speed in the
reverse direction and the time it takes to
decelerate in the forward direction (RACC =
Forward Deceleration). Factory adjusted to 1
second. (Maximum of 15 seconds).
Maximum Speed (MAX SPD). Refer to Section
10.2, on page 26.
The MAX trimpot is used to set the maximum
output voltage of the control which, in turn, sets
the maximum speed of the motor. In the
Torque Control Mode. The MAX trimpot setting
determines the unloaded motor speed.
Forward Current Limit (FCL). Refer to Section
10.3, on page 26. *
Sets the maximum amount of DC current that
the motor can draw. This determines the
amount of maximum motor torque in both the
Speed Control Mode and Torque Mode.
Reverse Current Limit (RCL) Refer to Section
10.3, on page 26. *
Sets the maximum amount of DC current that
the motor can draw. This determines the
amount of maximum motor torque in both the
Speed Control Mode and Torque Mode.
IR Comp (IR COMP). Refer to Section 10.4,
page 27. The IR Comp is used to stabilize motor speed
under varying loads.
Response (RESP). Refer to Section 10.5, on
page 28. This trimpot determines the dynamic response
of the control.
Deadband (DB). Refer to Section 10.6, on page
28.
The DB trimpot sets the amount of main speed
potentiometer rotation required to initiate
control voltage output. It is factory set to
approximately 0%. The DB trimpot also
determines the amount of delay that will occur
before regeneration starts.
Offset (OFFSET). Refer to Section 10.7, on
page 29.
This trimpot determines the amount of bias in
the forward or reverse direction. The trimpot is
factory set to provide approximately zero
offset, which means neither the forward nor
the reverse speed is favored.
Scale (SCALE). Refer to Section 10.8, on page
29.
This trimpot works in conjunction with the
MAX potentiometer for fine tuning of the
(voltage or current) of the incoming analog
signal.
* FCL and RCL also determine the maximum amount of regenerative breaking torque
depending on which direction is braking.
