D3 D2 D1 D0
6 0x4 0x0 ACK_TMO Cause:SSI signals not present or disturbed cause an error on CRC
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 Encoder1supply.
7 0x8 0x0 DT1_ERR
Cause:Encoder has detected malfunction and signals this to the drive via bit DT1.
Bits 16..31 contain the type of malfunction detected by the encoder.
Solution:See the encoder manufacturer's technical guide.
16.31 xxxx
Bit =0 =1
0 Light source OK Failure (1)
1 Signal amplitude OK Erroneous (1)
2 Position value OK Erroneous (1)
3 Over voltage NO Yes (1)
4 Under voltage NO Under voltage supply (1)
5 Over current NO Yes (1)
6 Battery OK Change the battery (2)
7..15
(1) Can also be set after the power supply is switched off or on.
(2) Only for battery-buffered encoders

3 0x8
Cause:voltage level not correct or disturbance on signals of incremental channels
A-B.
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
Encoder1supply, check parameter 2108 Encoder1signalVpp.
5 0x2 0x0 Cause:disturbed SSI signals cause a CKS error or Parity
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
Encoder1supply.
6 0x4 0x0
Cause:Encoder does not recognise the command that has been sent to it and replies
with ACK. The SSI signals not present cause a TMO error.
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
Encoder1supply.
8 0x1 0x0 0x0
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
Encoder1supply.
