Encoder 1
11
Enc 1 Cfg
Encoder 1 Configure
RW 16-bit
Integer
Configures the position direction, speed calculation method, signal type and active encoder channels used for Encoder 1 (secondary 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.
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 position count up/down associated with a given rotation direction internally. 1 = invert, 0 = do not invert

Enc 1 PPR
Encoder 1 Pulses Per Revolution
Configures the encoder module's secondary input (Encoder 1) for the Pulses Per
Revolution (Encoder Lines) of the A Quad B Encoder.
Default:
Min/Max:

Enc 1 FB Lss Cfg
Encoder 1 Feedback Loss
Configures how the drive reacts to an error status condition for Encoder 1 (secondary
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:
Min/Max:
3 = “FltCoastStop”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor“
3 = “FltCoastStop“
RW 32-bit
Integer

Enc 1 FB
Encoder 1 Feedback
Displays the position feedback value of Encoder 1 (secondary encoder). This should be
used as a source for the main control (Port 0) Feedback Select.
Default:
Min/Max:
