. Instructions on adjustment of potentiometer

1. The maximum rotation speed setting adjustment MAX SPD (see figure W1)
    With this potentiometer, the greatest output voltage of driver can be confirmed (the          

maximum motor rotation speed)

                Clockwise adjustment -----------to raise output voltage
             Counterclockwise adjustment ----- to reduce the output voltage

Note: when it is not sure that the maximum output voltage of driver matches with the rated     

voltage of motor, "MAX SPD" potentiometer should be adjusted to the minimum (the largest anti-clockwise), then the external speed potentiometer should be adjusted to the largest, and then "MAX SPD" potentiometer will be regulated again until the output voltage of driver and rated voltage of motor matches (that is, the motors rated rotation speed)

2. The lowest rotation speed setting adjustments: (Supplementary to the given signal) MIN SPD (see figure W2)
Adjust speed of potentiometer to the minimum, then adjust MIN SPD potentiometer, so you can determine the slowest rotation speed of motor.
           Clockwise adjustment ----------- to increase the auxiliary given signal
            Anti-clockwise adjustment ----- to reduce the auxiliary given signal
Note: External signal is set as 0, if there are still certain requirements of motors speed, it can be realized by adjustment of potentiometer (adjustment range 0 --- 30%) At this time, if given external given signal is increased, the rotation speed of motor will increase on the basis of "MIN SPD" setting value.

3. Soft-start time adjustment: ACCEL (see figure W3)
This adjustment of potentiometers ACCEL can make sure motors rising slope from the initial velocity up to the highest velocity (that is rising time, set time adjustable during 0-10 seconds). See figure 1
            Clockwise adjustment -----------to increase soft-start time
            Anti-clockwise adjustment ------ to reduce soft-start time

 Figure 1

4. Soft-stop time adjustment (The interior has been fixed): DECEL
Adjustment of potentiometers DECEL can make sure motors decline slope when speed dropped from the highest to the lowest (that is falling time, set time adjustable during 0-10 seconds). See Figure 2

Figure 2

5. Current limit adjustment: TORQUE (see figure W4)
Adjustment of the potentiometer can restrict drive plate to a maximum output current.
Based on your selection of the motors rated current, we can use this potentiometer to adjust driver output current to match the motor rated current.
            Clockwise adjustment ----------- to increase output current
           Counterclockwise adjustment -----------to reduce output current
Note: In the choice of driver, the drivers maximum output current should be 120% to 200% of motor rated current.

6.   Torque compensation adjustments: IR COMP (see figure W5)
Adjustment of the potentiometer can keep a constant rotation speed when motor works in different load.                        

              Clockwise adjustment---------- to increase torque compensation value  

Anti-clockwise adjustment----- to reduce torque compensation value
Note: If this potentiometer adjustment is in the best position, then it can achieve motors constant speed, constant power operation (within the speed regulation ratio 1:100), but the rated current of the chosen driver should be more than motors rated currents 200 % --- 300%.

7.        The highest output voltage adjustment: MAX COMP (see figure W6) (factory has adjusted well, and its usually not needed to adjust)
Adjustment of the potentiometer can be make sure drivers highest output voltage, adjustment range: 50% --- 110%
