MIN: Minimum Speed


The MIN trim pot is used to set the minimum
output frequency of the drive, which sets the
minimum motor speed. The minimum speed is
factory set to 10 Hz. Readjust the trim pot as
follows:

1. Rotate main speed potentiometer to the

minimum speed position (full
counterclockwise).

2. Increase setting of MIN trim pot so that motor

runs at desired minimum speed.



MAX: Maximum Speed


The MAX trim pot is used to set the maximum
output frequency of the drive, which sets the
maximum motor speed. The maximum speed is
factory set to full rated motor speed. Readjust
the trim pot as follows:

1. Rotate main speed potentiometer to the

maximum speed position (full clockwise).

2. Adjust setting of MAX trim pot so that motor

runs at desired maximum speed.


ACC: Acceleration


The ACC trim pot sets the time it takes the motor
to reach full speed from an initial zero start. The
trim pot is factory set to approximately 1.5
seconds. Adjust the ACC trim pot as required for
the application.

Note: When the control is set for 50 Hz
operation, the ACC trim pot will automatically
change to adjustable acceleration and
deceleration.

Note: Rapid acceleration may cause the current limit circuit to activate.
This will automatically extend the acceleration time.
