Note 2. The parameter settings for E1-04 through E1-10 will be changed automatically when one of
these patterns is selected. There are three possible settings for these parameters depending
on the Inverter’s capacity: a 0.4 to 1.5 kW V/f pattern, a 2.2 to 45 kW V/f pattern, and a 55 to
300 kW V/f pattern.
Note 3. The characteristics for these patterns are shown in the diagrams on pages 5-25 through 5-27.
H
Setting a User-defined V/f Pattern (Setting “F”)
Parameters E1-04 through E1-10 can be set by the user when E1-03 has been set to “F.” Refer to page
5-28 for details on setting these parameters.

H
Available PG Speed Control Cards
There are 4 types of PG Speed Control Cards, but only 2 types can be used with V/f control.
3G3FV-PPGA2: Phase-A (single) pulse input, input for open collector
3G3FV-PPGD2: Phase-A (single) pulse input, line driver inputs
Select the Card according to the application and install it in the Inverter as described in
2-2-6 Installing
and Wiring PG Speed Control Cards.
H
Setting the PG Pulse Number (F1-01)
Set the PG (pulse generator or encoder) pulse number in pulses/revolution. Set the number of phase A
or phase B pulses in one motor revolution. This parameter cannot be changed during operation.

Setting the Number of PG Gear Teeth (F1-12 and F1-13)
When “V/f control with PG feedback” is used, the motor can be operated even if there are gears between
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. The motor’s speed
will be calculated within the Inverter using the following equation:
Motor speed (r

min)
)
Number of pulses input from the PG
60
Number of PG pulses (F1–01)
Number of gear teeth 2 (F1–13)
Number of gear teeth 1 (F1–12)
