Flying restart circuit: Current
(Flying restart: Current)
0 ... [30] ... 100 %
The current set here is injected into the motor during the ying restart
process for the idencaon of the rotang eld frequency.
•
100 % ≡ Motor rated current 0x6075 (P323.00)
•
Reducing the current causes a reducon of the motor torque during
the ying restart process. A short-me starng acon or reversing of
the motor is prevented with low ying restart currents.
•
If the current is set too low, the rotang eld frequency cannot be
idened correctly.
•
If the current is increased, this improves the robustness of the ying
restart circuit.
•
In case of high mass ineras and high speeds, the ying restart circuit
may cause an overvoltage in the DC bus if no brake resistor is connec-
ted. In this case, the current must be reduced.
0x2BA1:002

Flying restart circuit: Start frequency
(Flying restart: Start frequency)
-599.0 ... [20.0] ... 599.0 Hz
The frequency set here denes the starng point for the ying restart
process.
•
The search starts in posive direcon.
•
The default seng 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 dened speed), the start
frequency can be adapted for reducing the ying restart me.
