Forward rotation in a typical motor:
Phase A leading in a typical PG:
Phase A
Phase B
The motor output axis
rotates in the counter-
clockwise direction with a
forward inverter command.
Phase A leads when the
input axis rotates clockwise.
H Setting the PG Pulse Output Monitor Division Ratio (F1-06)
This
parameter is ef
fective only when a 3G3FV
-PPB2 is used; it sets the division ratio used when the
pulse monitor output is connected to a pulse input device. This parameter cannot be changed during
operation.

The
first digit in the setting (0 or 1) is n and the second two digits (01 to 32) are m. The division ratio is
calculated from n and m with the following equation:
