Chapter 4 Parameters
4-178
10-17 Electrical Gear A (PG1 of PG card) Unit: 1
Control
mode
VFPG FOCPG
Factory Setting: 100
Settings 1 to 5000
10-18 Electrical Gear B (PG2 of PG card) Unit: 1
Control
mode
VFPG FOCPG
Factory Setting: 100
Settings 1 to 5000
Rotation speed = pulse frequency/encoder pulse (Pr.10-00) * PG Electrical Gear A / PG
Electrical Gear B.
10-19 Positioning for Encoder Position Unit: 1
Control
mode
VFPG FOCPG
Factory Setting: 0
Settings 0 to 65535 pulses
This parameter determines the internal position in the position mode.
It needs to be used with multi-function input terminal setting =35 (enable position
control).
When it is set to 0, it is the Z-phase position of encoder.
10-20
Range for Encoder Position Attained
Unit: 1
Control
mode
VFPG FOCPG
Factory Setting: 10
Settings 0 to 20000 pulses
This parameter determines the internal positioning position attained in the position
control mode.
10-23 Feed Forward Gain of APR Unit: 1
Control
mode
VFPG FOCPG
Factory Setting: 30
Settings 0 to 100
For position control, the larger this parameter is set, the less pulse differential it will be
and also make the position response be faster. But it may occur overshoot easily.
When the multi-function input terminal is set to 37 (ON), this parameter can be set by
requirement. If it is set to any value except 0 and adjust Pr.11-17 (Low-pass Filter Time
of PG2 Pulse Input) to lessen position overshoot and pulse differential. If it is set to 0,
