Issue: 5
Incremental encoder with frequency and direction (F and D), or
Forward and Reverse (CW and CCW) signals, with or without commutation signals
Encoder type Pr 3.38
Fd (1) for frequency and direction signals without commutation signals
Fr (2) for forward and reverse signals without commutation signals
Fd.SErVO (4) for a frequency and direction encoder with commutation signals
Fr.SErVO (5) for forward and reverse signals with commutation signals
Encoder power supply voltage Pr 3.36
5 V (0), 8 V (1) or 15 V (2)
If Ab encoder voltage is greater than 5 V, then the termination resistors must be disabled Pr 3.39 to 0
Encoder number of lines per
revolution
Pr 3.34 Set to the number of pulses per revolution of the encoder divide by 2.
Encoder termination selection Pr 3.39
0 = F or CW, D or CCW, Z termination resistors disabled
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
Encoder error detection level Pr 3.40
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)
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
NOTE
Absolute Sincos encoder with Hiperface or EnDat serial communications, or
Absolute EnDat communications only encoder
The Digitax ST is compatible with the following Hiperface encoders:
SCS 60/70, SCM 60/70, SRS 50/60, SRM 50/60, SHS 170, LINCODER, SCS-KIT 101, SKS36, SKM36, SEK-53.
Encoder type Pr 3.38
SC.HiPEr (7) for a Sincos encoder with Hiperface serial communications
EndAt (8) for an EnDat communications only encoder
SC.EndAt (9) for a Sincos encoder with EnDat serial communications
Encoder power supply voltage Pr 3.36 5 V (0), 8 V (1) or 15 V (2)
Encoder auto configure enable Pr 3.41
Setting this to 1 automatically sets up the following parameters:
Pr 3.33 Encoder turn bits
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.
Encoder comms baud rate
(EndAt and SC.EndAt only)
Pr 3.37 100 = 100 k, 200 = 200 k, 300 = 300 k, 500 = 500 k, 1000 = 1M, 1500 = 1.5 M, or 2000 = 2 M
Encoder error detection level
(SC.HiPEr and SC.EndAt only)
Pr 3.40
0 = Error detection disabled
1 = Wire break detection on Sin and Cos inputs
2 = Phase error detection
3 = Wire break detection on Sin and Cos inputs and phase error detection
