< Inductive voltage compensation >
The current loop response is improved by compensating the back electromotive force element induced by the motor
rotation. This improved the current command efficiency, and allows the acceleration/deceleration time constant to
the shortened.
< Adjustment method >
While accelerating/decelerating at rapid traverse, adjust the inductive voltage compensation gain (SV047: EC)
so that the current FB peak (MAX current 3) is a few % smaller than the current command peak (MAX current
2).

#2247
】
SV047 EC Inductive voltage compensation gain
Set the inductive voltage compensation gain. Standard setting value is "100".
If the current FB peak exceeds the current command peak, lower the gain.
---Setting range---
0 to 200 (%)
POINT
If the current FB peak (MAX current 3) becomes larger than the current command peak (MAX current 2)
(over compensation), an overcurrent (alarm 3A) will occur easily. Note that over compensation will occur easily
if the load inertia is large.
