11.22.12 PG Interface Card (OPC-PG)
The PG interface card is equipped with a 2 system pulse (ABZ-phase) input circuit and PG (pulse generator) power
supply output circuit, and the following functions can be realized by installing it in FRENIC-MEGA.
(1) Speed control with PG feedback signal (vector control with speed sensor, V/f control with speed sensor, dynamic
torque vector control with speed sensor) and servo lock function
(2) Pulse train input as frequency command
Note) By installing this interface card in FRENIC-MEGA, the inverter unit terminal [X6] and [X7] pulse train input
function cannot be used.
Applicable port
This interface card can be installed only in port C of the three FRENIC-MEGA option connection ports (A, B, and C
ports).
