Description of parameter
Cut-off Valve Present/Not Present
BOOL
Valid Values: 0 (NOT PRESENT); 255 (PRESENT)
Cut-off Valve control mode Close loop Control or ON-OFF control
BOOL
Valid Values: 0 (ON-OFF control); 255 (Closed loop control)
mAmp Current required to activate Cut-off valve
mAmp Current required to maintain to Cut-off in ON state
Cut Off Valve Activation TimeOut for COV Monitoring feature while
x10mSec entering Off Road state.
INFO: Setting this parameter to 0 will bypass off-road safety check
Changes the direction of the requested flow
BOOL
Valid Values: 0 (NO, DEFAULT OSPE/EHI); 255 (YES, DEFAULT EHPS)
PVED-CLS is attached to which type of valve?
dec
Valid Values: 0 (OSPE, EHI); 1 (EHPS)
Number of steering wheel turns lock-to-lock, without PVED-CLS
activated (hence pure hydraulic). Lock-to-lock is dependent on:

OSP displacement

EH-spool and pilot flow

Standby pressure (spring force)
dec

Cylinder volume
Contact your local technical support at Danfoss Power Solutions for
specific calculation, or simply do the measurement/exercise on the
vehicle
Resolution: 0.01 turns
OSP displacement, number of cubic centimeters per revolution
ccm Note: When the PVED-CLS is mounted on an EHPS this parameter
must be set equal to 0!
Cylinder stroke volume.
Acceptable values: 100-10000.
ccm
Note: Writing values >10000 will force to use automatic adjusted
cylinder stroke volume-value on WAS calibration
lpm EH valve size, defined in liters per minute
LVDT Offset compensation Enable/Disable
BOOL
Valid Values: 0 (DISABLE); 255 (ENABLE)
10 um
Absolute value of Spool neutral threshold range
(signed Dec)
Spool left most position copied by spool auto-calibration before the
x10um
internal calculation of the sector CRC
x10um Spool right most position copied by spool auto-calibration before the
internal calculation of the sector CRC
x10um Spool open loop dead-band offset copied by spool auto-calibration
before the internal calculation of the sector CRC
