P519 Skip freq uency area 2
S P
0.0 ... 50.0 Hz
{ 2.0 }
Masking range for the >Masking frequency 2< P518. This frequency value is added and
subtracted from the masking frequency.
Masking frequency range 2: P518 - P519 to P518 + P519
P520 Flying start
S P
0 ... 4
{ 0 }
This function is required to connect the FI to motors which are already rotating, e.g. in fan
drives. Motor frequencies >100Hz are only picked up in speed controlled mode (Servo mode
P300 = ON).
0 = Switched off , no flying start.
1 = Both directions , the FI looks for a speed in both directions.
2 = Directio n of setpoint , only search in the direction of the existing setpoint.
3 = Both dir ections after fault , only after mains failure and faults.
4 = Dir ection of set point a fter fault , only after mains failure and faults.
NOTE: For physical reasons, the flying start only operates above 1/10 of the nominal
speed of rotation (P202) or a minimum of 10Hz. For example, this means a
minimum speed of rotation of 300 rpm for a 4-pole 50Hz motor.
P521 Fly ing start resolution
S P
0.02... 2.50 Hz
{ 0.05 }
Using this parameter, the flying start search increment size can be adjusted. Values that are too
large affect accuracy and causes the FI to cut out with an overcurrent report. If the values are
too small, the search time is greatly extended.
P522 Fly ing start offset
S P
-10.0 ... 10.0 Hz
{ 0.0 }
A frequency value which is added to the frequency value found, e.g. to remain in the motor
range and so avoid the generator range and therefore the chopper range.
P523 Factory setting
0 ... 3
{ 0 }
By selecting the appropriate value and confirming it with the OK key, the selected parameter
range is entered in the factory setting. Once the setting has been made, the value of the
parameter automatically returns to 0.
0 = No change: Does not change the parameterisation.
1 = Load factory setting s : The complete parameterisation of the FI reverts to the factory
setting. All originally parameterised data is lost.
2 = Fact ory set ti ng w ith out bus: All parameters of the frequency inverter, but not the bus
parameters, are reset to the factory setting.
3 = Factory set ting w ith o ut motor data : All parameters of the frequency inverter, but not
the motor data, are reset to the factory setting.

The motor current for the I

t motor monitoring P535 can be weighted with the parameter P533.
Larger factors permit larger currents.
