*1 When warning conditions for 2 to 6 are established at the same time, the smallest number is returned.
*2 Once an estimation finishes even after a warning has occurred, the status will change to "Estimation has finished".

Description
The machine diagnostic status is returned.
[Bit 0 to 3: Friction estimation status at forward rotation]
0: Estimation in progress. (normal)
1: Estimation has finished. (normal)
2: The motor may have rotated/traveled more frequently in one
direction than the other. (warning)
3: The servo motor speed may be too slow for friction estimation.
(warning)
4: The change in the servo motor speed may be too small for friction
estimation. (warning)
5: The acceleration/deceleration time constants may be too short for
friction estimation. (warning)
6: The operation time may be insufficient. (warning)
[Bit 4 to 7: Friction estimation status at reverse rotation]
0: Estimation in progress. (normal)
1: Estimation has finished. (normal)
2: The motor may have rotated/traveled more frequently in one
direction than the other. (warning)
3: The servo motor speed may be too slow for friction estimation.
(warning)
4: The change in the servo motor speed may be too small for friction
estimation. (warning)
5: The acceleration/deceleration time constants may be too short for
