2C20 0 Machine diagnostic status
[Bit 0 to Bit 3: Friction estimation status at forward
rotation]
0: Normal (During estimation)
1: Normal (Estimation is completed)
2: Warning (the servo motor may rotate in one
direction too frequently.)
3: Warning (the servo motor speed may be too
slow for friction estimation.)
4: Warning (the change in the servo motor speed
may be small for friction estimation.)
5: Warning (the acceleration/deceleration time
constants may be too short for friction
estimation.)
6: Warning (the operation time may not be
enough.)
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".
[Bit 4 to Bit 7: Friction estimation status at reverse
rotation]
0: Normal (During estimation)
1: Normal (Estimation is completed)
2: Warning (the servo motor may rotate in one
direction too frequently.)
3: Warning (the servo motor speed may be too
slow for friction estimation.)
4: Warning (the change in the servo motor speed
may be small for friction estimation.)
5: Warning (the acceleration/deceleration time
constants may be too short for friction
estimation.)
6: Warning (the operation time may not be
enough.)
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".
[Bit 8 to Bit 11: Vibration estimation status]
0: During estimation
1: Estimation is completed.
[Bit 12 to Bit 15: reserved]
The value at reading is undefined.
