4.3.1 FMIN potentiometer
Function:
The potentiometer serves to set the minimum speed of the motor (pull-in).
To set-up the minimum speed
•
Turn FMIN potentiometer CCW to zero (CCW = min speed , CW = min speed )
•
Set Jumper ADJ to position B
•
Press RUN to see whether the motor starts and adjust FMIN potentiometer until the motor
starts with the application load.
Note
•
The motor will reach the MIN speed within the first step (pull-in speed range) if no ramp is set
with ACC and DEC potentiometers.
•
The FMIN speed ranges from 10 to 6000 steps/s
4.3.2 FMAX potentiometer
Function:
The potentiometer is used to determine the maximum speed the motor will reach. To reach
this speed the motor may require an acceleration and deceleration ramp.
The set-up is done as follows:
•
Set the min speed to its lowest value if necessary (turn FMIN CCW to zero)
•
Set the ACC and DEC ramp by adjusting the corresponding potentiometers on the
board (see ACC and DEC Adjustment)
•
Set the max speed by adjusting the FMAX potentiometer (CCW = max speed , CW = max
speed )
•
Set Jumper ADJ to position B
•
Press RUN to see whether the motor starts.
If the motor does not accelerate to the speed
(stalling of motor shaft), press STOP and increase the ACC time (acceleration time
given to the motor to reach the FMAX speed) by turning the ACC potentiometer
CCW. It may also happen that you have to decrease the max speed.
Note
Maximum speed changes if FMIN setting is changed, the difference is kept constant.
4.3.3 ACC and DEC Adjustment
Function:
The potentiometers adjust the time during which the motor will accelerate from FMIN to FMAX speed
or decelerate from FMAX to FMIN speed.
Turning the potentiometers CW will decrease the acceleration time and increase the
acceleration rate (t
acc
and
t
dec
), the motor speed increases/decreases faster
