Installation
3G3FV-PPGX2 (For Flux Vector Control Mode Only)
Three-phase
200 VAC (400 VAC)
Note 1. Shielded, twisted-pair 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.
H Wiring PG Speed Control Card Terminal Blocks
Use no more than 30 meters of wiring for PG (encoder) signal lines and no more than 50 meters for
3G3FV-PPGD2 and 3G3FV-PPGX2, and keep them separate from power lines. Use shielded, twisted-
pair wire for pulse input and pulse output monitor wire, and connect the shield to the shielded wire con-
nection terminal.
