A-phase
pulse input
B-phase
pulse input
Note When connecting to a voltage-output-type PG (encoder), select a PG that has an output imped-
ance with a current of at least 12 mA to the input circuit photocoupler (diode). The E6B2-CWZ3E
cannot be used.
3G3FV-PPGD2 (For V/f With PG Feedback Mode Only)
Three-phase
200 VAC (400 VAC)
Note 1. Twisted-pair shielded wire must be used for signal lines.
Note 2. 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.
Note 3. The length of the pulse generator's wiring must not be more than 50 meters.
