Pg Interface (5 V Line Driver) Card (Opc-G1 - Fuji Electric Frenic Mega Series User Manual

4.4.2.5 PG interface (5 V line driver) card (OPC-G1-PG2)
The PG interface (5 V line driver) card has the following circuits:
- Shifted phase pulse train (A, B, and Z phases) input circuit for speed feedback (5 V line driver output
type PG)
- Wire break detection circuit (Detection of wire breaks on the Z phase can be cancelled.)
- Power output circuit for feeding power to the connected PG (pulse generator)
Mounting this interface card on the FRENIC-MEGA enables the following:
(1) Speed control (vector control with speed sensor, V/f control with speed sensor, dynamic torque vector
control with speed sensor) using PG feedback signals, and servo-lock function
(2) Pulse train input as frequency commands
Ports available for the interface card
This interface card can be connected to the C-port only, out of three option connection ports (A-, B-, and
C-ports) provided on the FRENIC-MEGA.
