[5] PG interface card (OPC-G1-PG)
The PG interface card has a two-shifted pulse train (A, B, Z phase) input circuit for speed feedback and a
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
Note: Using this interface card disables the pulse train frequency command via the digital input terminal
[X7] on the inverter.
Ports available for the communications 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.
Applicable ROM version
This interface card is applicable to inverters having a ROM version G1S10100 or later.
