A07980 — Drive: Rotating measurement activated

A07980 is an informational alarm: the rotating measurement has been activated, and the drive carries it out at the next switch-on command. On the vector drive objects the manuals describe the same procedure as the automatic speed controller optimization. No acknowledgement is required — the alarm clears itself once the measurement has been completed successfully or the selection is reset. The G115D and G120C manuals list the alarm only by name.

The S120/S150 manual for the SERVO drive objects explains what the measurement means for the machine: the motor can accelerate up to the maximum speed and with maximum torque. During the measurement only the parameterized current limit (p0640) and the maximum speed (p1082) are effective; the direction inhibit (p1959.14, p1959.15) and the ramp-up/ramp-down time (p1958) let you influence the motor's behavior.

• The rotating measurement (on vector drive objects: the automatic speed controller optimization) is activated. It is not executed immediately — the measurement runs at the next switch-on command.
• On the S120/S150 SERVO drive objects the alarm additionally signals a measurement in which only the current limit p0640 and the maximum speed p1082 remain effective.

1. Confirm that the rotating measurement is intended. If it is, no action is necessary — switch the drive on and let the measurement run to completion.
2. If the measurement was selected unintentionally, deselect it: p1960 = 0 on the S120/S150 SERVO drive objects, or p1900 = 0 on the vector drive objects. The alarm is withdrawn for these settings.
3. While the measurement is running, parameters cannot be saved (p0971; on the G130/G150 and S120/S150 vector drive objects also p0977) — saving is simply not possible during this time.

• p1960 — rotating measurement selection; on the S120/S150 SERVO drive objects the alarm is withdrawn for the setting p1960 = 0.
• p1900 — motor data identification and rotating measurement; setting p1900 = 0 withdraws the alarm on the vector drive objects.
• p0640 — current limit; on the S120/S150 SERVO drive objects it remains effective during the rotating measurement.
• p1082 — maximum speed; the upper limit for the motor during the rotating measurement on the S120/S150 SERVO drive objects.
• p1959 — direction inhibit bits p1959.14 and p1959.15 influence how the motor moves during the rotating measurement (S120/S150 SERVO drive objects).
• p1958 — ramp-up/ramp-down time that shapes the motor's motion during the rotating measurement (S120/S150 SERVO drive objects).
• p0971 — drive object parameters cannot be saved while the rotating measurement is running (note printed for G120, G120XA, G130/G150 and S120/S150).
• p0977 — all parameters likewise cannot be saved during the rotating measurement (G130/G150 and S120/S150 vector drive objects).

No acknowledgement is needed — the manuals' remedy reads Not necessary. The alarm is withdrawn automatically after the rotating measurement has been successfully completed. If the measurement is cancelled instead, the alarm disappears for the setting p1960 = 0 (S120/S150 SERVO drive objects) or p1900 = 0 (vector drive objects).

One caution from the S120/S150 manual for the SERVO drive objects: if a POWER ON or a warm restart is performed with motor data identification selected, the motor data identification request is lost and has to be selected again manually following ramp-up.
