Roll Position
1500 Roll Psn Config
Roll Position Indicator Configuration
RW 16-bit
Integer
Configuration for the Roll Position Indicator function.
Bit 0 “Enable” – Enables the Roll Position Indicator function.
Bit 1 “Preset” – At rising edge of this bit, P1504 [Roll Psn Preset] is loaded in P1505 [Roll Psn Offset].
Bit 2 “Rereference” – Permit changing the offset value of P1511 [RP Psn Output] without affecting actual position.
Bit 3 “EGR Select” – 0 = EGR with gear ratio input as numerator and gear ratio output as denominator.
1 = EGR with gear ratio output as numerator and gear ratio input as denominator.
1501 Roll Psn Status
Roll Position Indicator Status
RO 16-bit
Integer
Status of the Roll Position Indicator function.
Bit 0 “Enable” – Acknowledges that Roll Position Indicator function is enabled.
Bit 1 “Rereference” – Acknowledges that rereferencing of P1511 [RP Psn Output] is active.

1504 Roll Psn Preset
Roll Position Indicator Preset
Provides a pre-set position value. At rising edge of Bit 1 “Preset” in P1500 [Roll Psn
Config], this parameter value is loaded in P1511 [RP Psn Output]. Note: P1511 [RP Psn
Output] is limited by P1509 [RP Unwind].

1505 Roll Psn Offset
Roll Position Indicator Offset
Provides position offset, which is summed after the EPR and used to trim the phase of
the position feedback.
