D7..D4 D3 D2 D1 D0
Solution: Check the connection of the encoder-drive channel B,
check the connection of the screen, check the Encoder 1 supply
voltage.
Check parameters 2102 Encoder 1 supply and 2104 Encoder 1
input cfg (if encoder 1 is used).
Check parameters 5102 Encoder 2 supply and 5104 Encoder 2
input cfg (if encoder 2 is used).
2 0x4 CHZ Cause: no impulses or disturbance on incremental channel Z.
Solution: Check the connection of the encoder-drive channel Z,
check the connection of the screen, check the Encoder 1 supply
voltage.
Check parameters 2102 Encoder 1 supply and 2104 Encoder 1
input cfg (if encoder 1 is used).
Check parameters 5102 Encoder 2 supply and 5104 Encoder 2
input cfg (if encoder 2 is used).
