îš‹ Using PG Feedback Option Cards
To get a more precise speed control the inverter can be equipped with a PG option card to connect a pulse gen-
erator. Three different PG cards can be used, the PG-B2, the PG-X2 and the PG-Z2. Refer to page 2-30,
Option Card Models and Specifications to see details.

îš„Using PG Speed Control Card
There are two types of PG Speed Control Card that can be used in V/f control with PG and Closed Loop Vec-
tor control:
• PG-B2: A/B-phase pulse input, compatible with complementary outputs.
• PG-X2: A/B/Z-phase pulse input, compatible with line drivers (RS-422).
• PG-Z2: Dual encoder PG feedback card (two times phase A, B, Z), selectable line driver (RS422) or open collector
inputs
For the mounting instructions, specifications and connection diagrams refer to page 2-30, Installing and Wir-
ing Option Cards.
îš„Setting Number of PG Pulses (F1-01)
Set the number of PG (Pulse Generator/Encoder) pulses in pulses per revolution.

IMPORTANT
If Open Loop Vector control is used and a PG card is installed, the speed detected by the PG card is dis-
played in the monitor parameter U1-05. Therefore the PG constant has to be set in parameter F1-01. The
direction of the speed detection can be changed by parameter F1-05.
To change the U1-05 value to the internally calculated value remove the PG card.
