2C20 Machine diagnostic status (Machine diagnostic
status)
[Bit 0 to Bit 3: Friction estimation status at
forward rotation]
0: Normal (Friction is being estimated.)
1: Normal (Estimation is completed.)
2: Warning (The servo motor may rotate in one
direction too frequently.)
3: Warning (The servo motor speed may 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 (Friction is being estimated.)
1: Normal (Estimation is completed.)
2: Warning (The servo motor may rotate in one
direction too frequently.)
3: Warning (The servo motor speed may 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.
