8.3 Status monitoring
The internal state quantity of the servo drive can be read out through the RS-485
communication port, but cannot be written. The state quantity is stored in 16bit data, in which the
value is accurate to decimal places. When read out through the communication port, the value is
amplified by 10 times and 100 times. This situation is the same as the parameter reading part, and
the assembly sequence of the relevant state quantities is as follows:
1000H: Display motor speed
1001H: Display current position (pulse) low 16 bits
1002H: Display current position (pulse) high 16 bits
1003H: Display position command (pulse) low 16 bits
1004H: Display position command (pulse) high 16 bits
1005H: Display position deviation (pulse) low 16 bits
1006H: Display position deviation (pulse) high 16 bits
1007H: Display motor torque
1008H: Display motor current
1009H: Display the current control mode
100AH: Display current temperature
100BH: Display speed command
100CH: Display torque command
100DH: Displays the absolute position of the rotor during one revolution low 16 bit
100EH: Displays the absolute position of the rotor during one revolution high 16 bit
100FH: Display input terminal status
1010H: Display output terminal status
1011H: Display encoder input signal
1012H: Display the main circuit bus voltage value
1013H: Display alarm code
1014H: Displays the logic chip version number
