DUAL INCREMENTAL ENCODERS: The encoder used for positioning is mounted elsewhere on the machine.
Using this scheme, the need for a “positive drive” setup is somewhat reduced. A second motor-mounted encoder is
required. The ratio between the motor and the machine-mounted encoder must be entered into parameters P3-03
and P3-04, and the PPR of the encoder must be entered into P3-02. The drive requires a PG-W2 encoder
feedback card.
Note: Wiring for the encoder marker pulse (Z+ and Z-) is only required if using a “Homing w/marker” homing
routine (P2-01 = 4 or 5).
