11.22.13 PG Interface (5 V Line Driver) Card (OPC-PG2)
The PG interface (5 V line driver) card is equipped with a 5 V line driver output type PG (pulse generator) 1 system
pulse (A-, B-, Z-phase) input circuit, a wire break detection circuit (Z-phase can be canceled), and a PG power
supply output circuit.
The following functions can be realized by installing this interface card 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
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).
