Available PG Speed Control Cards
J
There are 4 models of PG Speed Control Cards, but only 2 models can be used with vector control.
D
PG-A2: Phase-A/Phase-B pulse inputs, complementary output
•
PG-D2: Phase-A/Phase-B/Phase-Z pulse inputs, line drivers
•
Select the Card according to the application and install it in the Inverter as described in 3.7 Installing
D
and Wiring PG Speed Control Cards.

Setting the PG Pulse Number: F1-01

J
Set the PG (pulse generator or encoder) pulse number in pulses/revolution.
D
Set the number of phase A or phase B pulses in one motor revolution.

Setting the Number of PG Gear Teeth: F1-12, F1-13

J
When "V/f control with PG feedback" is used, the motor can be operated even if there are gears be-
D
tween the motor and PG because the responsiveness is lower than it is with vector control.
Set the number of teeth on the gears if there are gears between the motor and PG.
D
The motor speed will be calculated within the Inverter using the following equation:

A gear ratio of 1 (F1-12 = F1-13 = 1) will be used if either of these constants is set to 0.

Selecting Integral Operation During Acceleration/Deceleration: F1-07

J
When "V/f control with PG feedback" is used, integral control during acceleration and deceleration
D
can be enabled or disabled with F1-07.
Set F1-07 to "1" (integral control enabled) if you want to keep the motor speed as close to the frequency
D
reference as possible during acceleration and deceleration. Set F1-07 to "0" (integral control disabled)
if you want to prevent the occurrence of overshooting/undershooting.
