The machine diagnostic status is returned. The description is as follows.
Bit
Description
0 to 3
Friction estimation status at forward rotation
0: Friction is being estimated. (normal)
1: Estimation is completed. (normal)
2: The servo motor may rotate in one direction too frequently. (warning)
3: The servo motor speed may too slow for friction estimation. (warning)
4: The change in the servo motor speed may be small for friction estimation. (warning)
5: The acceleration/deceleration time constants may be too short for friction estimation. (warning)
6: The operation time may not be enough. (warning)
When warning conditions for 2 to 6 are met at the same time, the smaller number is returned.
When an estimation is completed even though a warning has once occurred, the status changes to Estimation is
completed.
4 to 7
Friction estimation status at reverse rotation
0: Friction is being estimated. (normal)
1: Estimation is completed. (normal)
2: The servo motor may rotate in one direction too frequently. (warning)
3: The servo motor speed may too slow for friction estimation. (warning)
4: The change in the servo motor speed may be small for friction estimation. (warning)
5: The acceleration/deceleration time constants may be too short for friction estimation. (warning)
6: The operation time may not be enough. (warning)
When warning conditions for 2 to 6 are met at the same time, the smaller number is returned.
When an estimation is completed even though a warning has once occurred, the status changes to Estimation is
completed.
8 to 11
Vibration estimation status
0: During estimation
1: Estimation is completed.
12 to 15
(reserved) The value at reading is undefined.
