F07330 Flying restart: Measured search current too low
Drive object: VECTOR
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: During a flying restart, it was identified that the search current reached is too low.
It is possible that the motor is not connected.
Remedy: Check the motor feeder cables.
F07331 FlyRestart: Not supported
Drive object: VECTOR
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: It is not possible to power-up with the motor rotating (no flying restart). In the following cases, the "flying restart" func-
tion is not supported:
Permanent-magnet and separately-excited synchronous motors (PEM, FEM): Operation with V/f characteristic.
Permanent-magnet synchronous motor (PEM): Sensorless operation without a Voltage Sensing Module (VSM)
being connected.
Remedy: - de-activate the "flying restart" function (p1200 = 0).
- change the open-loop/closed-loop control mode (p1300).
- connect a Voltage Sensing Module (VSM) (voltage measurement).
A07350 (F) Drive: Measuring probe parameterized to a digital output
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The measuring probe is connected to a bi-directional digital input/output and the terminal is set as output.
Alarm value (r2124, decimal):
9: DI/DO 9 (X122.8)
10: DI/DO 10 (X122.10)
11: DI/DO 11 (X122.11)
13: DI/DO 13 (X132.8)
14: DI/DO 14 (X132.10)
15: DI/DO 15 (X132.11)
Remedy: - set the terminal as input (p0728).
- de-select the measuring probe (p0488, p0489, p0580).
Reaction upon F: OFF1
Acknowl. upon F: IMMEDIATELY
A07400 (N) Drive: DC link voltage maximum controller active
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The DC link voltage controller has been activated because the upper switch-in threshold has been exceeded (r1242).
The ramp-down times are automatically increased in order to maintain the DC link voltage (r0026) within the permis-
sible limits. There is a system deviation between the setpoint and actual speeds.
When the DC link voltage controller is switched-out (disabled), this is the reason that the ramp-function generator
output is set to the speed actual value.
See also: p1240 (Vdc controller or Vdc monitoring configuration)
Remedy: If the controller is not to intervene:
- increase the ramp-down times.
- disable the Vdc max controller
If the ramp-down times are not to be changed:
- use a chopper or regenerative feedback unit
Reaction upon N: NONE
Acknowl. upon N: NONE
