MM-PCM Series
Acceleration (ACCEL)
The ACCEL setting determines the time the motor takes to ramp to a
higher speed. See Specifications on page 1 for approximate acceleration
times. ACCEL is factory set for the shortest acceleration time (full CCW).
To set the acceleration time:
1. Set the speed adjust potentiometer or input voltage signal for
minimum speed. The motor should run at minimum speed.
2. Set the speed adjust potentiometer or input voltage signal for
maximum speed. Measure the time it takes the motor to go
from minimum to maximum speed.
3. If the time measured in step 2 is not the desired acceleration
time, turn the ACCEL trim pot CW for a longer acceleration time
or CCW for a shorter acceleration time. Repeat steps 1 through
2 until the acceleration time is correct.
Deceleration (DECEL)
The DECEL setting determines the time the motor takes to ramp to a
lower speed. See Specifications on page 1 for approximate deceleration
times. DECEL is factory set for the shortest deceleration time (full CCW).
To set the deceleration time:
1. Set the speed adjust potentiometer or input voltage signal for
maximum speed. The motor should run at maximum speed.
2. Set the speed adjust potentiometer or input voltage signal for
minimum speed. Measure the time it takes the motor to go
from maximum to minimum speed.
3. If the time measured in step 2 is not the desired deceleration
time, turn the DECEL trim pot CW for a longer deceleration time
or CCW for a shorter deceleration time. Repeat steps 1 through
2 until the deceleration time is correct.
