5 Parameter
BU 0600 en-3221 181
P558 Flux delay S P
Setting range 0, 1, 2... 5000 ms
Factory setting { 1 }
Description
ASM
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 excitation of the stator winding. 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 flux delay can be set or disabled.
PMSM
When used with PMSM, the dwell time can be set via this parameter during
rotor position identification using the dwell method. Total dwell duration = 2.5
x P558 [ms]
Note Setting values that are too low can reduce the dynamics and starting torque.
Setting values
Value Meaning
0 Switched off
1 Automatic calculation
2 … 5000 Time set in [ms]
P559 DC run-on time S P
Setting range 0.00 ... 30.00 sec
Factory setting { 0.50 }
Description After a stop signal and elapse of the brake ramp, direct current is applied to the motor
for a short time. This should completely stop the drive. 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).
P560 Parameter, Saving mode S
Setting range 0 … 2
Factory setting { 1 }
Description "
Parameter saving mode
".
Note If BUS communication is used to implement parameter changes, it must be ensured
that the maximum number of write cycles to the EEPROM (100,000 x) is not
exceeded.
Setting values
Value Meaning
0 Only in RAM Changes to the parameter settings are not written to the EEPROM.
All saved settings which were made before changing the saving
mode 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 Saving in RAM and EEPROM not possible. (No parameter changes
are adopted)
