Standard quadrature encoder with or without commutation signals (A, B, Z or A, B, Z, U, V, W), or
Sincos encoder with or without UVW commutation signals
Device Type (03.038)
AB (0) for a quadrature encoder without commutation signals *
AB Servo (3) for a quadrature encoder with commutation signals
SC (6) for a Sincos encoder without commutation signals *
SC Servo (12) for a Sincos encoder with commutation signals
Supply Voltage (03.036)
5 V (0), 8 V (1) or 15 V (2)
If output voltage from the encoder is >5 V, then the termination resistors must be disabled. Set Pr 03.039 to 0
Rotary Line Per Revolution (03.034) Set to the number of lines or sine waves per revolution of the encoder.
Termination Select (03.039)
(AB or AB Servo only)
0 = A, B, Z termination resistors disabled
1 = A, B termination resistors enabled and Z termination resistors disabled
2 = A, B, Z termination resistors enabled
Error Detection Level (03.040)
So for example, to enable the wire break error detection, set Pr 03.040 to 0001.
Incremental encoder with Frequency and Direction (F and D) or Forward and Reverse (CW and CCW) signals with or without commutation
signals.
Device Type (03.038)
FD (1) for frequency and direction signals without commutation signals*
FR (3) for forward and reverse signals without commutation signals*
FD Servo (4) for frequency and direction signals with commutation signals
FR Servo (5) for forward and reverse signals with commutation signals
Supply Voltage (03.036)
5 V (0), 8 V (1) or 15 V (2)
If output voltage from the encoder is >5 V, then the termination resistors must be disabled. Set Pr 03.039 to 0
Rotary Line Per Revolution (03.034) Set to the number of pulses per revolution of the encoder divided by 2.
Termination Select (03.039)
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
Error Detection Level (03.040)
So for example, to enable the wire break error detection, set Pr 03.040 to 0001.
