Read-Write Data Type
Dual Incremental Encoder
Encoder 0
1Enc 0 Cfg
Encoder 0 Configure
RW 16-bit
Integer
Configures the position direction, speed calculation method, signal type and active encoder channels used for Encoder 0 (primary encoder).
Bit 0 “Z Channel Enbl” – Configures the Channel Z to be used and monitored for Phase Loss. A value of 0 = the Z channel will be ignored.
Bit 1 “A Chan Only” – Configures the module to use only the A channel, and ignore the B channel. In this mode, direction cannot be determined, and the position
counter will always count up.
Bit 2 “Edge Mode” – Configure the module to use AB edge time data for speed calculation rather than accumulated count. Recommended for low speed operation.
Bit 4 “Single Ended” – Configure when the A Quad B encoder has single ended signals. In this mode, Phase Loss detection is disabled.
0 = Differential, 1 = Single Ended
Bit 5 “Direction” – Inverts the feedback count up/down associated with a given rotation direction internally. 1 = invert, 0 = do not invert
2Enc 0 PPR
Encoder 0 Pulses Per Revolution
Configures the encoder module's primary input (Encoder 0) for the Pulses Per Revolution
(Encoder Lines) of the A Quad B Encoder. When using a permanent magnet motor, the
pulses per revolution (PPR) must be an exponent of two. For example: 512, 1024, 2048,
4096, 8192…524288…

3 Enc 0 FB Lss Cfg
Encoder 0 Feedback Loss Configure
Configures how the drive reacts to an error status condition for Encoder 0 (primary
encoder).
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run.
Enable with P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
Default:
Options:
3 = “FltCoastStop”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor”
3 = “FltCoastStop”
RW 32-bit
Integer
4Enc 0 FB
Encoder 0 Feedback
Displays the position feedback value of Encoder 0 (primary encoder). This should be
used as a source for the main control (Port 0) Feedback Select.
