Lvdt Compensation And Spool Threshold At Boot-Up - Danfoss PVED-CLS User Manual

ENGINEERING TOMORROW
For EHPS following spools are available:
Furthermore, if the PVED-CLS is mounted on a EHPS, then the flow direction needs to be inverted (P3080 set to 255)
and the turns lock-to-lock on the steering wheel (when the electronics are not activated, hence pure hydraulic
steering) needs to be entered in P3082 (resolution is 0.01 turns).

LVDT compensation and spool threshold at boot-up

7.1.4.1 LVDT compensation
The LVDT feedback signal, which is the EH-spool feedback to the PVED-CLS, can be compensated for temperature
changes by setting P3089 to 255.
Important
Danfoss recommends to keep the LVDT compensation always active. LVDT compensation should only be disabled when
performing diagnostic troubleshooting on the PVED-CLS.
7.1.4.2 Spool threshold at boot-up
When power is applied to the PVED-CLS, the spool needs to be in neutral. The +/- tolerance, given in x10µm, is
controlled by P3090. If the spool is outside this threshold during boot-up and the PVED-CLS is mounted on an
