Operation Outline

1. The value of the variable resistor connected to the SGDH SERVOPACK analog input

terminal is read to the MP940.

2. An output based on the value read from the variable resistor is output to the SERVO-

PACK connected to the analog output (AO) to turn the motor.

3. The encoder pulses for the motor driven in step 2 are read using the MP940 counter, and

the servomotor connected to the SGDH SERVOPACK is moved by the number of
pulses read every scan cycle.
