Closed-Loop Vector Control Solution – YASKAWA PG-B1 73600-A0024 | VS-616G5 Series
Where This Product Is Used
The YASKAWA PG-B1 (Part No. 73600-A0024) is a pulse generator (PG) speed feedback option card designed for installation in YASKAWA VS-616G5 and VS-616PC5 series AC variable frequency drives. It enables closed-loop vector control by feeding real-time encoder signals back to the drive’s control board, making it indispensable in applications where precise speed regulation and torque control are critical.

Application-Specific FAQ
Q: Is the PG-B1 compatible with the VS-616G3 or VS-616G7 series?
A: No. The PG-B1 (73600-A0024) is specifically designed for the VS-616G5 and VS-616PC5 option slot. For VS-616G3, the correct card is PG-A1; for VS-616G7, please consult the drive’s option card compatibility table.
Q: What encoder PPR (pulses per revolution) does the PG-B1 support?
A: The PG-B1 accepts encoders from 60 PPR to 60,000 PPR. The value is set via drive parameter F1-01. 1024 PPR is the most common selection for general-purpose closed-loop vector applications.
Q: Can I use an open-collector encoder output with the PG-B1?
A: The PG-B1 is designed for line driver (RS-422 differential) encoder outputs. Open-collector encoders require an external pull-up resistor network or a signal converter; consult YASKAWA application note TM.AFD.12 for wiring guidance.
Q: Will the drive fault if the PG-B1 is installed but no encoder is connected?
A: Yes. With A1-02 = 3 (closed-loop vector), the drive will generate a PGO (PG Open) fault at startup if no encoder signal is detected. Ensure encoder wiring is complete before energizing.
Q: Do you provide a warranty on this card?
A: Yes. New-in-box units carry a 12-month warranty. Tested-used units carry a 90-day warranty. Contact us for full warranty terms.
