A07980 Drive: Rotating measurement activated
Drive object: SERVO
Reaction: NONE
Acknowledge: NONE
Cause: The rotating measurement is activated. For the rotating measurement, the motor can accelerate up to the maximum
speed and with maximum torque. Only the parameterized current limit (p0640) and the maximum speed (p1082) are
effective. The behavior of the motor can be influenced using the direction inhibit (p1959.14, p1959.15) and the ramp-
up/ramp-down time (p1958).
The rotating measurement is carried out at the next power-on command.
See also: p1960 (Rotating measurement selection)
Remedy: None necessary.
The alarm automatically disappears after the rotating measurement has been successfully completed or for the set-
ting p1960 = 0.
A07980 Drive: Rotating measurement activated
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The rotating measurement (automatic speed controller optimization) is activated.
The rotating measurement is carried out at the next power-on command.
See also: p1960 (Rotating measurement selection)
Remedy: None necessary.
The alarm disappears automatically after the speed controller optimization has been successfully completed or for
the setting p1900 = 0.
A07981 Drive: Enable signals for the rotating measurement missing
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The rotating measurement cannot be started due to missing enable signals.
Remedy: - acknowledge faults that are present.
- establish missing enable signals.

F07982 Drive: Rotating measurement encoder test
Drive object: VECTOR
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the encoder test.
Fault value (r0949, interpret decimal):
1: The speed did not reach a steady-state condition.
2: The speed setpoint was not able to be approached as the minimum limiting is active.
3: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
4: The speed setpoint was not able to be approached as the maximum limiting is active.
5: The encoder does not supply a signal.
6: Incorrect polarity.
7: Incorrect pulse number.
8: Noise in the encoder signal or speed controller unstable.
9: Voltage Sensing Module (VSM) incorrectly connected.
