Maximum Motor Speed.

The maximum motor RPM is the maximum rated speed for the motor being used with the A250 control. The default nominal value is 11.5 RPM. This value should be changed to reflect the actual motor RPM based on motor type and tuning results (See Drive Tuning following this section). Initially, this value should be set to the nameplate RPM for the motor/gearbox being used, before proceeding to Drive Tuning.

1)Turn the Accel & Decel pots fully counter-clockwise.

2)Press the “Min” button.

3)Check rotation direction. Disk should turn (counterclockwise).

4)Swap A+ & A- leads With Power Off to change rotation direction.

5)Press “Max” button.

6)Adjust max pot to adjust max speed to match target value.

7)Press “Min” button.

8)Adjust min pot to adjust min speed to match target value.

9)Repeat steps 5-8 until readings stabilize.

10)If maximum speed value cannot be obtained, change max RPM on the Maximum Motor Speed screen to match the closest value obtained on this screen.

Encoder Pulses.

The encoder pulses are determined by the number of encoder steps per motor revolution (usually 30) multiplied by the gearbox ratio. In the case of the standard motor, the ratio is 190:1, so 30 X 190 = 5700. To change the value, press the value on the screen to activate the keyboard. Key in the correct value and press the

key.
