Parameter Setting value / Description / Note Device Supervisor
Parameter
set
P516 Skip frequency 1
S P
0.0 ... 400.0 Hz
[ 0.0 ]
The output frequency around the frequency value (P517) set here is masked.
This range is transmitted with the set brake and acceleration ramp; it cannot be continuously
supplied to the output. Frequencies below the absolute minimum frequency should not be set.
0.0 =
Masking frequency inactive
P517 Skip frequency area 1
S P
0.0 ... 50.0 Hz
[ 2.0 ]
Masking range for the >Masking frequency 1< P516. This frequency value is added and
subtracted from the masking frequency.
Masking frequency range 1: P516 - P517 to P516 + P517
P518 Skip frequency 2
S P
0.0 ... 400.0 Hz
[ 0.0 ]
The output frequency around the frequency value (P519) set here is masked.
This range is transmitted with the set brake and acceleration ramp; it cannot be continuously
supplied to the output. Frequencies below the absolute minimum frequency should not be set.
0.0 =
Masking frequency inactive
P519 Skip frequency 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 already rotating motors, 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 circuit.
1 = Both directions,
the FI looks for a speed in both directions.
2 = Setpoint value direction,
searches only in the direction of the setpoint value present.
3 =
Both directions, only following mains supply failure and error
4 =
In setpoint direction, only following mains supply failure and error
NOTE:
For physical reasons, the flying start circuit 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 Flying start resolution
S P
0.02... 2.50 Hz
[ 0.05 ]
Using this parameter, the flying start circuit 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 Flying 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 ... 2
[ 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 settings:
The complete parameterisation of the FI reverts to the factory
setting. All originally parameterised data is lost.
2 = Factory settings without bus:
All parameters of the frequency inverter, with the exception
of the bus parameter, are reset to the factory setting.
