P556
Braking resistor
(Brake resistor)
S
1 ... 400
Ω
{ 120 }
Value of the brake resistance for the calculation of the maximum brake power to protect the
resistor.
Once the maximum continuous output (P557) including overload (200% for 60s) is reached, an I

t
limit error (E003.1) is triggered. Further details in P737.

P557
Brake resistor type
(Brake resistor power)
S
0.00 ... 320.00 kW
{ 0.00 }
Continuous power (nominal power) of the resistor, to display the actual utilisation in P737. For a
correctly calculated value, the correct value must be entered into P556 and P557.
0.00 =
Monitoring disabled

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 =
Time set in [ms]
NOTE:
Setting values that are too low can reduce the dynamics and starting torque.

P559
DC Run-on time
(DC Run-on time)
S
P
0.00 ... 30.00 s
{ 0.50 }
Following a stop signal and the braking ramp, a direct current is briefly applied to the motor to
fully bring the drive to a stop. Depending on the inertia, the time for which the current is applied
can be set in this parameter.
The current level depends on the previous braking procedure (current vector control) or the static
boost (linear characteristic).

Parameter, Saving mode
(Saving mode parameter)
S
0 ... 2
{ 1 }
0 = Only in RAM
, changes to the parameter settings are no longer saved on the EEPROM.
All previously saved settings are retained, even if the FI is disconnected from the mains.
1 = RAM and EEPROM
, all parameter changes are automatically written to the EEPROM
and remain stored there even if the FI is disconnected from the mains supply.
2 = OFF
, no saving in RAM and EEPROM possible (no parameter changes are accepted)
NOTE:
If BUS communication is used to implement parameter changes, it must be ensured
that the maximum number of write cycles (100,000 x) in the EEPROM is not
exceeded.

Positioning
The parameter group P6xx is used to set the POSICON positioning control and is included above the
version SK 530E.
