Using PG Speed Control Card

There are four types of PG Speed Control Card that can be used in V/f control with PG.

PG-A2: A-phase (single) pulse input, compatible with open collector or complimentary outputs.

PG-B2: A/B-phase pulse input, compatible with complimentary outputs.

PG-D2: A-phase (single) pulse input, compatible with line drivers.

PG-X2: A/B/Z-phase pulse input, compatible with line drivers.

There are two types of PG Speed Control Cards that can be used for flux vector control.

PG-B2: A/B phase pulse inputs, complementary outputs

PG-X2: A/B/Z phase pulse inputs, line driver outputs

For the connection diagram, refer to page 2-36.

Setting Number of PG Pulses

Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or B-
phase pulses per 1 motor rotation in F1-01.

„

Matching PG Rotation Direction and Motor Rotation Direction

Parameter F1-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating
forwards, set whether it is A-phase driven or B-phase driven. Make this setting when using PG-B2 or PG-X2.

F1-12

Number of PG
Gear Teeth 1

Sets the gear ratio between the
motor shaft and the encoder (PG).

A gear ratio of 1 will be used if
either of these parameters is set to
0. This function is not available in
flux vector control.

Configures the PG open (PGO)
function. PGO will be detected if
no PG pulses are detected for a
time longer than F1-14. See
