Parameter list of pressure over limit detection
The detection of pressure feedback can be activated via bit1 of F4.00.
F4.15: When the feedback pressure goes beyond [F4.15] bar for [F4.17] s, the
warning (d0.88 = 1) will be triggered for the pressure feedback surpassing the
maximum system allowed pressure.
F4.16: When the feedback pressure goes beyond [F4.16] bar for [F4.18] s, the
failure (d0.89 = 1) will be triggered for the pressure feedback surpassing the
pump limit pressure, and then drive stops.
