Mains: Error Switch-
Off
In the case of a phase failure, the error switch-off takes place after
5 minutes, fault F0703 is displayed. During this time, the warning mes-

Mains & Motor: Er-
ror Switch-Off
The phase monitor switches the frequency inverter off:
− immediately with error message F0403 in the case of a motor phase
failure
− after 5 minutes with error message F0703 in the case of a mains
phase failure
20 -
Mains: Shutdown
In the case of a mains phase failure, the drive is stopped after 5
minutes, fault F0703 is displayed.
21 -
Mains & Motor:
Shutdown
− The drive is switched off: immediately, in the case of a motor phase
failure
− The drive is stopped: after 5 minutes in the case of a mains phase
failure
7.4.8 Automatic Error Acknowledgment
578 Allowed No. of Auto-Acknowl.
579 Restart Delay
The automatic error acknowledgment enables acknowledgment of the faults Overcurrent F0507 and
Overvoltage F0700 without intervention by an overriding control system or the user. If one of the
aforementioned errors occurs, the frequency inverter switches the power semi-conductors off and
waits for the time stated with the parameter
Restart Delay 579. If the error is acknowledged, the
speed of the machine is determined with the quick Search Run function and synchronized to the
ro-tating machine. The automatic error acknowledgment makes use of "Quick Synchronization" opera-
tion mode, regardless of the
Flying Start Operation Mode 645. The information given on this function
in chapter
7.
3.5 "Flying Start" must be observed.
With parameter
Allowed No. of Auto-Acknowl. 578, you can define the number of automatic error
acknowledgements which are permitted within 10 minutes.
An acknowledgement repeated above the permissible number within 10 minutes will result in the fre-
quency inverter being switched off.
The errors Overcurrent F0507 and Overvoltage F0700 have separate error acknowledgement coun-
ters.

7.5 Reference Values
7.5.1 Reference frequency channel
475 Reference Frequency Source 1
492 Reference Frequency Source 2
Via the reference frequency channel, you can define how the reference rotary frequency for the motor
is to be specified. For each of parameters
Reference Frequency Source 1 475 and Reference Fre-
quency Source 2
492, you can select a reference value specification option. The selected reference
values are added and output as rotary frequency reference value for the motor.
The settings of frequency limits (Parameter
Minimum Frequency 418 and Maximum Frequency 419)
and blocking frequencies (parameter 1st Blocking Frequency 447, 2nd Blocking Frequency 448) as
well as
Frequency Hysteresis 449 are considered.
