Notice

Possible impairment of devices!

If the object 0x80n8:11 “CRC polynomial” is set to “0”, the data transmission is not CRC secured anymore. Therefore wrong counter values may not be detected by the encoder!

	Setting the encoder supply voltage Condition: To write 0x8008:12 “Supply Voltage”, the value 0x72657375 (ASCII: “user”) must be set in 0xF008 “Code word”. Set the value into index 0x8008:12 “Supply Voltage (Specification in steps of 0.1 V). Only the values 50 (5.0 V) and 90 (9.0 V) are permissible. This setting applies to both channels. Before switching to 9.0 V, make sure that both BiSS encoders support the extended voltage range! The encoder supply voltage is set for both channels in object 0x8008:12!
