11.25 PG interface card (OPC-E2-PG3)
This option card has the pulse (ABZ phase) input circuit of 2 systems and the power output circuit for PG (pulse
generator).
By exchanging this option card with the control circuit terminal board that is installed in FRENIC-Ace main body as
a standard, the following expansion functions can be used.
(1) By the feedback signal by PG, speed control (vector control with speed sensor and PG, V/f control with
speed sensor, peripheral speed constant control).
(2) Simplified position control is possible by feedback signal of PG.
(3) Master-follower synchronous drive is possible by feedback signal by pulse line input or PG.
(4) Pulse line input is possible as the frequency command.
Refer to Chapter 5 for details of each function.
If this card is used, the pulse line input function of the inverter main body terminal X5 cannot be used.
Applicable ROM version
This interface card is applicable to inverters with a ROM version 0300 or later.

If an encoder exceeding the above current has to be connected, it is necessary to
use an external power supply.
The above current is the total value including the pulse line input interface side.
*1: These values are approximate. They might be shorter depending on the wire type or noise environment.
