(magnetization time)
0 / 1 / 2 ... 5000 ms 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 to provide the excitation of the stator
{ 1 }
winding. The duration depends on the size of the motor and is automatically set in the factory
setting of the VFD.
For time-critical applications, the magnetizing time can be set or deactivated.

DC Run-on time
P559
(DC run-on time)
0.00 ... 30.00 s 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
{ 0.50 }
can be set in this parameter.
The current level depends on the previous braking procedure (current vector control) or the static
boost (linear characteristic).

Setting values that are too low can reduce the dynamics and starting torque.
RAM only, changes to the parameter settings are no longer saved on the EEPROM. All
previously saved settings are retained, even if the VFD is disconnected from the power.
RAM and EEPROM, all parameter changes are automatically written to the EEPROM
and remain stored there even if the VFD is disconnected from the power supply.
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.
PLC: A stored PLC program is also protected by the settings "0" or "2". However,
with the setting "0" the PLC program can also not be loaded or executed.
