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 100 meters.
•
The direction of rotation of the PG can be set in user parameter F1-05 (PG Rotation). The factory preset if
•
for motor forward rotation, A-phase advancement.

Wiring Terminal Blocks

Do not use more cables longer than 100 meters for wiring the PG (encoder) and keep them separate from
power lines.
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield to the
shield connection terminal.
