•
When connecting to a voltage-output-type PG (encoder), select a PG that has an output impedance with
a current of at least 12 mA to the input circuit photocoupler (diode).
•
The pulse monitor dividing ratio can be changed using parameter F1-06.

•
Shielded twisted-pair wires must be used for signal lines.
•
Do not use the pulse generator's power supply for anything other than the pulse generator (encoder).
Using it for another purpose can cause malfunctions due to noise.
•
The length of the pulse generator's wiring must not be more than 50 meters.
