Notes
Internal encoder value
This value is used by the cam control unit of the digital output module for evaluating the
configured cams.
Register value that was requested via the control interface, see table "Addressable regis-
ters in LD_SLOT".
Feedback in response to the SLOT request via the control interface.
0 = Backward motion of last motion
•
1 = Forward motion of last motion
•
0 = No forward motion
•
1 = Forward motion (current encoder value)
•
0 = No backward motion
•
1 = Backward motion (current encoder value)
•
0 = Hysteresis is not active
•
1 = Hysteresis is active
•
0 = No encoder direction available
•
Note:
If no encoder direction is available, the configured substitute values are output for all chan-
nels that operate as a cam track (CTRL_DQ.CHx = 1).
1 = Encoder data can be used for cam output
•
0 = Encoder data is invalid
•
Note:
When the encoder data is invalid, the value status is set to 0.
1 = Encoder data detected as invalid
•
This bit changes its value following a successful write operation.
Status for pulsed cam output of channels 0 to 3
Bit 0 for channel 0: 0 = No pulsed cam output, 1 = Pulsed cam output activated
•
Bit 1 for channel 1: 0 = No pulsed cam output, 1 = Pulsed cam output activated
•
Bit 2 for channel 2: 0 = No pulsed cam output, 1 = Pulsed cam output activated
•
Bit 3 for channel 3: 0 = No pulsed cam output, 1 = Pulsed cam output activated
•
Bits 4 to 7: Reserved
•
