0x2BA0 Acvate
ying restart Acvaon of the addional "ying restart" funcon.
If the "ying restart" funcon is acvated ("1: on") and the inverter disa-
ble is deacvated, a ying restart process is automacally started for
determining the current motor speed if the following condions are
met:
•
The V/f characterisc control is set as motor control.
•
The CiA402 mode is selected as drive mode.
•
The "ying restart" funcon is not blocked via bit 2 in the Inverter
control word (0x2830).
•
No DC-injecon braking is acve.
•
No mot
or phase failure has been idened.

Start frequency of ying restart algorithm

If it is foreseeable at which frequency the motor can be restarted on
the y, set the frequency here.
0x2BA3 Integraon me
1 ... [600] ... 60000 ms
Integraon me of the angle controller
•
The default seng is adapted for medium-power machines.
•
A guide value for the integraon me can be calculated as a funcon
of the motor power with the following equaon: Ti = 1.1 µ/W * Rated
power (0x2C01:006) + 9.4 ms
•
For accelerang the search process, this guide value can be reduced.
•
If the ying restart frequency oscillates too much, increase the inte-
graon me again.
•
A longer integraon me extends the me for a ying restart of the
drive.

0x2BA5 Delay me
0 ... [0] ... 10000 ms
In order to prevent the start of a ying restart process if the controller
inhibit me is too short, a minimum acve me for the inverter disable
can be set here in order that a ying restart process will be started.
As a pulse inhibit > 500 ms causes a controller inhibit, this also applies to
pulse inhibit.
