How to monitor position/speed/alarm code, etc.
Question
I would like to monitor the current position, speed, current value, torque, alarm code, etc. of the AC servo system.
What should I do?
Answer
Please use the status monitoring register in the User’s Manual Chapter 8 8.3 P0.xxx monitoring parameters.
If you set the value listed in Table 8.3 in the parameter “P0.017: Select content displayed by status monitoring register 1” on the panel or via communication, the corresponding data will be set in status monitoring register 1.
There are 5 status monitoring registers in total. (1:P0.009 to 5:P0.013)
Data you want to monitor (example)
| Parameter address | Monitor items |
|---|---|
| P0.009 | Current position of motor encoder |
| P0.010 | Actual speed of motor |
| P0.011 | Actual truque of motor |
| P0.012 | Actual current of motor |
| P0.013 | Alarm code |
Setting Example
| Parameter address | Set value | Monitor items |
|---|---|---|
| P0.017 | 0(0h) | Feedback position (unit: PUU) |
| P0.018 | 51(33h) | Speed feedback(immediate) (unit: 0.1rpm) |
| P0.019 | 54(36h) | Torque feedback (Unit: 0.1%) |
| P0.020 | 55(37h) | Currrent feedback (unit: 0.01A) | P0.021 | 28(1Ch) | Alarm code |
* Convert to hexadecimal, and the upper 16 bits are the alarm code.
* 209184(DEC) -> 33120(HEX): Alarm code is 3.
