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.
16.31

10.2.1 Reset Speed fbk loss alarm
The reasons for activating the Speed fbk loss alarm and the information acquired by the encoder are shown in
parameter 2172 SpdFbkLoss code.
If no card has been installed the Speed fbk loss [22] alarm is generated and no cause is displayed in parameter 2172
SpdFbkLoss code. Several causes may be present at the same time.
If no card is recognised, the system runs a routine that always returns Speed fbk loss [22] active without specifying a
cause.
