NOTE
If output voltage from the encoder is >5V, then the termination resistors must be disabled Pr 3.39 to 0
Set to the number of pulses per revolution of the encoder divide by 2.
Pr 3.34 See section 7.5.3 Restriction of encoder number of lines per revolution on page 135 for restrictions
on this parameter.
0 = F or CW, D or CCW, Z termination resistors disabled
Pr 3.39 1 = F or CW, D or CCW termination resistors enabled and Z termination resistors disabled
2 = For CW, D or CCW, Z termination resistors enabled
0 = Error detection disable
1 = Wire break detection on F & D or CW & CCW, and Z inputs enabled
2 = Phase error detection (Fd.SErVO and Fr.SErVO only)
Pr 3.40
3 = Wire break detection on F & D or CW & CCW, and Z inputs and Phase error detection
(Fd.SErVO and Fr.SErVO only)
Termination resistors must be enabled for wire break detection to operate
SC.HiPEr (7) for a Sincos encoder with Hiperface serial communications
Pr 3.38 EndAt (8) for an EnDat communications only encoder
SC.EndAt (9) for a Sincos encoder with EnDat serial communications
Pr 3.36 5V (0), 8V (1) or 15V (2)
Setting this to 1 automatically sets up the following parameters:
Pr 3.33 Encoder turn bits
Pr 3.41 Pr 3.34 Encoder number of lines of revolution (SC.HiPEr and SC.EndAt only) *
Pr 3.35 Encoder single turn comms resolution
Alternatively these parameters can be entered manually.

0 = Error detection disabled
