For diagnostic purposes, the frequency detected when the motor has been restarted on
the fly is displayed in 0x2BA1:008 (P718.08).
Name / value range / [default setting]
0x2BA1:001
(P718.01)
Flying restart circuit: Current
(Flying restart: Current)
0 ... [30] ... 100 %
The current set here is injected into the motor during the flying restart
process for the identification of the rotating field frequency.
100 % ≡ Motor rated current 0x6075 (P323.00)
Reducing the current causes a reduction of the motor torque during
the flying restart process. A short-time starting action or reversing of
the motor is prevented with low flying restart currents.
If the current is set too low, the rotating field frequency cannot be
identified correctly.
If the current is increased, this improves the robustness of the flying
0x2BA1:002

Flying restart circuit: Start frequency
(Flying restart: Start frequency)
-599.0 ... [20.0] ... 599.0 Hz
The frequency set here defines the starting point for the flying restart
process.
The search starts in positive direction.
The default setting is adjusted to standard asynchronous motors.
In case of systems with a known search speed (e.g. torque-controlled
drive systems that are to synchronise to a defined speed), the start
frequency can be adapted for reducing the flying restart time.

restarted on the fly.
