Optimize transient response
MP1520 defines the transient response when accelerating and braking. The approach behaviour is
optimized to the target position.

MP1530 correct
MP1530 too high
MP1530 too low
Since MP1520 is effective for all axes, the worst axis determines the entry value. No axis should
show an overshoot.
If MP1520 is set too low then the positioning times to the target position will increase substantially.
Optimize MP1520 with great care!
