For each D0, D1, D2, D3 value other than 0x0 search for the sub-values it can be divided into in table 1.
In the table regarding the type of encoder in use, search for the sub-values obtained from each D0, D1, D2, D3
digit in the corresponding columns Value.D0, Value.D1, Value.D2, Value.D3
Value.D1=2H
Cause: (CRC_CKS_P)disturbed SSI signals cause a CKS error or Parity.
Valore.D1=8H
Cause: (DT1_ERR) Encoder has detected a malfunction and signals this to the drive via Error bit. Bits 16..31
contain the type of malfunction detected by the encoder.

0 0x1 CHA Cause:no impulses or disturbance on incremental channel A.
Solution:Check the connection of the encoder-drive channel A, check the connec-
tion of the screen, check the encoder supply voltage.
Check parameters 2102 Encoder1supplyand 2104 Encoder1inputcfg (if
encoder 1 is used).
Check parameters 5102 Encoder2supply and 5104 Encoder2inputcfg (if
encoder 2 is used).
1 0x2 CHB Cause:no impulses or disturbance on incremental channel B.
Solution:Check the connection of the encoder-drive channel B, check the connec-
tion of the screen, check the Encoder 1 supply voltage.
Check parameters 2102 Encoder1supplyand 2104 Encoder1inputcfg (if
encoder 1 is used).
Check parameters 5102 Encoder2supply and 5104 Encoder2inputcfg (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 connec-
tion of the screen, check the Encoder 1 supply voltage.
Check parameters 2102 Encoder1supplyand 2104 Encoder1inputcfg (if
encoder 1 is used).
Check parameters 5102 Encoder2supply and 5104 Encoder2inputcfg (if
encoder 2 is used).

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
Encoder1supply, check parameter 2108 Encoder1signalVpp.
