“$I_VEL_PTP[1]” is the integral--action factor of the speed controller for PTP motion.
The I component $I_VEL_PTP[ ] can be used to set the build--up speed of the controller
output in the event of a deviation from the command value. Generally, the I component
should be as small as possible, resulting in a fast rise. However, if the I component is too
small, this can render the control loop unstable; this results in poor positioning or causes the
drive to buzz loudly.
If the I factor of the controller is set too low, this cause vibrations.
Guide values:
= 90
for small external motors
(types C0, C, CS, D, E)
= 200 .. 500 for large external motors
(types A01, A0, A, B, G1, I, I1, H, HS)
