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.
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.
