Connecting Pulse

Inputs (FQM1-MMP21/

MMA21)

Connect the output from an encoder to the connector in the following way, according to the port's counter operation.

	Port 1			Port 2			Signal name		Encoder output
Pin number			Pin number					Phase Differential	Increment/Decrement	Pulse + Direction
								Input Mode	Pulse Input Mode	Input Mode
24	V: 1	(5)	24	V: 2	(6)	Encoder input A		Encoder phase-A input	Increment pulse input	Pulse input
24	V: 7	(11)	24	V: 8	(12)	Encoder input B		Encoder phase-B input	Decrement pulse input	Direction signal input
					Note		The numbers in parentheses are the pin numbers on the negative side.
Example							• The wiring for an encoder (24 V) with an open-collector output is shown
							below. These examples are for encoders with phases A, B, and Z.
