When advance angle compensation values 1 and 2 are set.
Advance
angle
amount
Advance angle amount =
Set angle 1 + (Set angle 2 – Set angle 1) ÷ (Set
speed 2 – Set speed 1) × (Resolver speed – Set
speed 1)
Set angle 1
Advance angle amount =
Set angle 1 ÷ Set speed 1 × Resolver speed
Set
speed 2
Saturation
speed
Resolver speed (r/min)
Set angle 2
Set
speed 1
Saturation speed =
Set speed 1 + (359 (or 719) – Set angle 1) ÷
(Set angle 2 – Set angle 1) × (Set speed 2 – Set
speed 1)
Note 1. The data for advance angle compensation value with the lower speed (out of advance angle
compensation values 1 and 2) will become the set speed 1 and the set angle 1.
Note 2. The maximum compensation value is 359 (for 360 resolution) or 719 (for 720 resolution). A
compensation greater than one rotation cannot be made.
Note 3. Except for 0, the same speed data cannot be set for advance angle compensation values 1
and 2.
When advance angle compensation values 1 and 2 are set and the set angle 2 is
smaller than the set angle 1.
Advance
angle

Advance angle amount =
Set angle 1 ÷ Set speed 1 × Resolver speed
Set angle 2
Advance angle amount =
Set angle 1 + (Set angle 2 – Set angle 1) ÷ (Set
speed 2 – Set speed 1) × (Resolver speed – Set
speed 1)
Set

Saturation speed =
Set speed 1 + Set angle 1 ÷ (Set angle 1 – Set angle 2) × (Set
speed 2 – Set speed 1)
Note The lowest compensation value is 0.
