MOD_
INCR
Cause: voltage level not correct or disturbance on signals of incremental channels
A-B.
Solution: Check the connection of the encoder-drive channels A-B, check the
connection of the screen, check the encoder supply voltage, check parameter 2102
Encoder 1 supply, check parameter 2108 Encoder 1 signal Vpp.

4 0x1 0x0 MOD_ABS
Cause: voltage level not correct or disturbance on signals of absolute SinCos chan-
nels.
Solution: Check the connection of the the encoder-drive channels A-B, check the
connection of the screen, check the encoder supply voltage, check parameter 2102
Encoder 1 supply, check parameter 2108 Encoder 1 signal Vpp.

Cause: An error occurred during setup.
Solution: Check the connection of the clock and encoder-drive data, check the
connection of the screen, check the encoder supply voltage, check parameter 2102
Encoder 1 supply, check parameter 2112 Encoder 1 SSI bits.
