● 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 [22] activation
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.
16.31
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
● Speed fbk loss [22] alarm with Hiperface absolute encoder
Bit Value Name Description
3 0x08 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 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 Encoder supply.
6 0x40 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 Encoder supply.
8 0x100
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 [22] activation.
Bit Value Name Description
7 0x80 DT1_ERR Cause: Encoder has detected malfunction and signals this to the drive via Error bit. Bits 16..31 contain the type of malfunction detected by the encoder.
Solution: See the encoder manufacturer's technical guide.
