2 encoders can be connected to a b maXX 4000 at most. Accordingly errors can appear
in function module 1 and function module 2. The term „encoder 1“ or „encoder 2“ in the
column „device part“ stands for one of the five currently existing encoder module types.
80 CRC has generated an error Check the encoder cable and the encoder connection
81 Invalid command
82 Error in response telegram
83 Alarm bit is set Restart b maXX 4000
84 Memory is used Check the encoder cable and the encoder connection
85 Incorrect data checksum
86 Motor data length and/or data version of
encoder and controller firmware are not identi-
cal
87 No EnDat interface
88 Exceeding the evaluable transmission format Use another type of length measurement system
89 Exceeding the evaluable measuring step
90 Signal period length < measuring step length
91 EnDat 2.2: Error initializing master module Exchange module (standard controller) or exchange controller (ES
controller)
92 EnDat 2.2: Timeout measuring the signal trans-
fer time
Exchange encoder cable or module (standard controller) or change
controller (ES controller)
93 EnDat 2.2: Error - signal transfer compensation
is switched-off
Exchange module (standard controller) or exchange controller (ES
controller)
94 EnDat 2.2: Encoder type does not support
EnDat2.2 (command set, power supply, clock
frequency)
Use suitable encoder type
95 EnDat 2.2: RM bit is not set, reference of
encoder absolute position is not available
96 Error lightning Exchange encoder
97 Error signal amplitude
98 Error position value
99 Error overvoltage Exchange module (standard controller) or exchange controller (ES
controller)
100 Error undervoltage
101 Error overcurrent
102 Error battery Exchange encoder
103 -111 reserved
112 Position error detected at multiple request Check encoder cable or installation
