ADL300 - Fast installations and commissioning Pag. 43 of 52
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.
• Speed fbk loss [22] alarm with EnDat absolute encoder
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.
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.
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
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.
(1) Can also be set after the power supply is switched off or on.
(2) Only for battery-buffered encoders
