2. Counter Design Examples 2.5 A B-phase Pulse High-speed Counter z Wiring for Differential Input ( high-speed, high-noise condition ) DVP32EH00M High-speed Input A Differntial Output B z Wiring for Differential Output Servo Driver PLC Control Purpose: z DVP32EH00M sends AB-phase pulse to control the servo at a speed of 10,000 pulses per second. The motor rotation will be encoded by the encoder and the result will be transferred to the input points (differential input) of PLC high-speed counter. If the counted value in PLC high-speed counter is different from the number of pulse sent by the MPU, the alarm will be enabled. Devices:
