0x2BA0 Activate flying restart Activation of the additional "flying restart" function.
If the "flying restart" function is activated ("1: on") and the inverter disa-
ble is deactivated, a flying restart process is automatically started for
determining the current motor speed if the following conditions are
met:
•
The V/f characteristic control is set as motor control.
•
The CiA402 mode is selected as drive mode.
•
The "flying restart" function is not blocked via bit 2 in the Inverter
control word (
0x2830 ).
•
No DC-injection braking is active.
•
No motor phase failure has been identified.

0 ... [15] ... 100 %
0x2BA2 Start frequency
-600.0 ... [20.0] ... 600.0 Hz Start frequency of flying restart algorithm
•
If it is foreseeable at which frequency the motor can be restarted on
the fly, set the frequency here.
0x2BA3 Integration time
1 ... [600] ... 60000 ms Integration time of the angle controller
•
The default setting is adapted for medium-power machines.
•
A guide value for the integration time can be calculated as a function
of the motor power with the following equation: Ti = 1.1 µ/W * Rated
power (
0x2C01:006 ) + 9.4 ms
•
For accelerating the search process, this guide value can be reduced.
•
If the flying restart frequency oscillates too much, increase the inte-
gration time again.
•
A longer integration time extends the time for a flying restart of the
drive.
0x2BA4 Minimum deviation
0.00 ... [5.00] ... 90.00 ° Setting of the minimum permissible deviation.
0x2BA5 Delay time
0 ... [0] ... 10000 ms In order to prevent the start of a flying restart process if the controller
inhibit time is too short, a minimum active time for the inverter disable
can be set here in order that a flying restart process will be started.
As a pulse inhibit > 500 ms causes a controller inhibit, this also applies to
pulse inhibit.
