Parameter Setting value / Description / Note Available with option
P550 ControlBox Orders always visible
0 ... 3
[ 0 ]
It is possible to save a dataset (parameter set 1 to 4) of the connected FI in the optional ControlBox .
It is saved inside the Box in a non-volatile memory and can therefore be transferred to other NORDAC
700E devices with the same databank version (comp. P743).
0 = No function
1 = FI  ControlBox, dataset is written from the connected FI to the ControlBox.
2 = ControlBox  FI, dataset is written from the ControlBox to the connected FI.
3 = Exchange, the FI dataset is exchanged with the ControlBox dataset. With this variant, no data is
lost. It is continuously exchangeable.
Note: If parameterisation from old FI's must be loaded into new FI's, then the ControlBox must
previously be written to by the new FI (=1). The dataset to be copied from the old FI can then be read
out and copied to the new FI.
P551 Drive profile always visible
0 … 1
[ 0 ]
According to the option the relevant process data profiles can be activated with this parameter.
This parameter is only effective for pluggable technology modules (SK TU1-
…)
Note:
With the use of the internal CANbus (CANnord) via the integrated customer interface (SK
CU1-
…), the settings in this parameter have no effect. The DS402 profile cannot be
activated.

P554 Chopper minimum always visible
65 ... 100 %
[ 65 ]
The switching threshold of the brake chopper can be influenced with this parameter. An optimised
value for numerous applications is set in the factory setting. This parameter can be increased for
applications where pulsating energy is returned (crank drives) to minimise brake resistance power
dissipation.
An increase in this setting leads to a faster overvoltage FI switch off.
P555 P-limit chopper always visible
5 ... 100 %
[ 100 ]
With this parameter it is possible to program a manual (peak) power limit for the brake resistor. The
switch-on delay (modulation level) for the chopper can only rise to a certain maximum specified limit.
Once this value has been reached, irrespective of the level of the link voltage, the inverter switches the
resistance currentless.
The result would be an overvoltage switch-off of the FI.
P556 Braking resistor always visible
3 ... 400

[ 120 ]
Value of the brake resistance for the calculation of the maximum brake power to protect the resistor.
Once the maximum continuous output (P557) has been reached, then an error I2t Limit (E003) is
initiated.
P557 Brake resistor type always visible
0.00 ... 100.00 kW
[ 0.00 ]
Continuous resistor output (nominal power) for the calculation of the maximum braking power.
0.00 = Monitoring deactivated
P558 (P) Flux delay always visible
0 / 1 / 2 ... 500 ms
[ 1 ]
The ISD control can only function correctly if there is a magnetic field in the motor. For this reason, a
DC current is applied before starting the motor. The duration depends on the size of the motor and is
automatically set in the factory setting of the FI.
For time critical applications, the magnetizing time can be set or deactivated.
0 = Switched off
1 = automatic calculation
2...500 = corresponding set value
Note: Values that are too low can reduce the dynamics and torque development during start-up.
