Trimpot Set Up
Introduction
Some of the operational parameters of the P5000 can be set or changed using the five
trimpots located on the top of the drive. The trimpots are labeled SMOOTH, PROFILE,
ACCEL, CW, CCW. The trimpots set the following:
•
Step
Smoothness
•
Low-End Resonance Reduction
•
Acceleration and Deceleration rates (used in VCO Mode)
•
Clockwise and Counter-clockwise Velocity (used in VCO Mode)

3.2.1 Smooth
Trimpot
The SMOOTH trimpot adjusts the motor smoothness at very low speeds by equalizing the
microstep size at the motor's full-step locations. Unadjusted, the microstep size at the full-step
location may be too large or too small. Run the motor at about 10 RPM and adjust the trimpot
for desired performance. Together, the SMOOTH and PROFILE trimpots provide the
smoothest possible motor performance.
3.2.2 Profile
Trimpot
The PROFILE trimpot minimizes motor low-speed resonance vibration by selecting the
optimum current profile from eight different shaped current waveforms. Run the motor at its
low-speed resonance RPM (between 30 to 100 RPM). Adjust the trimpot to minimize vibration.
Together, the SMOOTH and PROFILE trimpots provide the smoothest possible motor
performance.
3.2.3 CW, CCW and Accel Trimpots
The CW, CCW, and ACCEL trimpots are only applicable if the P5000 drive is in VCO Mode
(SW1 OFF).
The CW trimpot sets the clockwise velocity. Likewise, the CCW trimpot sets the counter-
clockwise velocity. There are three different VCO velocity ranges available. For example if
SW3 and SW4 are in the ON position, the velocity range is 0 to 234 RPM. The CW and CCW
trimpots are smooth, single-turn trimpots. When rotated completely counter-clockwise, the
trimpot is set to zero speed. When rotated completely clockwise, the trimpot is set to the
maximum speed of the specified range.
