MIN: Minimum Speed

The MIN trim pot is used to set the minimum

 

HERTZ

output frequency of the drive, which sets the

 

17

 

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

24

counterclockwise).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Increase setting of MIN trim pot so that motor

 

MIN

runs at desired minimum speed.

 

 

 

 

 

 

 

 

 

 

 

 

MAX: Maximum Speed

 

 

 

 

 

 

 

 

The MAX trim pot is used to set the maximum

 

 

 

 

 

 

 

 

 

HERTZ

 

output frequency of the drive, which sets the

 

 

 

40

 

 

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).

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.
