 Speed fbk loss [22] alarm with EnDat absolute encoder

Bit Value Name Description

3 0x08 MOD_INCR 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 Encoder supply, check parameter 2108 Encoder signal Vpp.

5 0x20 CRC_CKS_P 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 Encoder supply.

8 0x100 Setup error 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 supply.

The following conditions occur while resetting the encoder following Speed fbk loss

Bit Value Name Description

6 0x40 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 Encoder supply.

7 0x80 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.

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)
