Control bit Notes
SLOT You use this value to specify the write accesses for the registers addressable with LD_SLOT.
ACCESS_SLOT •
RD/WR = 0: Read access to the addressed register.
RD/WR = 0 --> 1: Writing is enabled at a transition from "0" to "1".
•
Note:
After a successful write operation, the addressed register is read.
LD_SLOT
•
You use this value to select the register, see Notes on the control interface (Page 80).
CTRL_DQ.CHx You use this bit to specify how channel X is controlled.
0 = Direct channel writing by the CPU.
•
1 = Take channel value from the cam track.
•
SET_DQ.CHx Values for the direct channel writing by the CPU.
The bit is processed in combination with bit CTRL_DQ.x = 0.
0 = Channel X outputs the value 0.
•
1 = Channel X outputs the value 1.
•

Raw copied encoder value
When hysteresis is active (STS_REG.HYS = 1), the HYS_START and HYS_END
registers contain the boundary points of the hysteresis.
Read: Number of detected errors in the encoder data (change from 1 to 0 of bit
INP_OK in byte STS_REG of the feedback interface).
Write: Resetting the counter
