Short overview of the relevant parameters:
How to parameterise the flying restart function:
1. Activate the flying restart circuit by selecting "1: On" in C00990
.
• Every time the controller is enabled, a synchronisation to the rotating or
standing drive is carried out.
When the Lenze setting is used, most applications do not require additional
controller settings.
If additional settings are necessary, proceed as follows:
2. Define the process and hence the speed range/rotational frequency range in
C00991
which is to be examined by the flying restart circuit:
• positive speed range (n
≥ 0min
-1
)
• negative speed range (n
≤ 0min
-1
)
• total speed range
3. Define the starting frequency.
The starting frequency which defines the starting point of the flying restart
function is 10 or -10 Hz for processes 0 ... 3 and has been pre-optimised for
standard motors.
If process 4 is selected in C00991
, an arbitrary starting frequency can be defined via
C00992
. This is especially recommended for motors with higher rated frequencies.
• We recommend to define a starting frequency of approximately 20 % of the
rated motor frequency to enable a safe and fast connection to standing drive
systems.
• For systems with a known search speed (e.g. torque-controlled drive systems
which are to synchronise to a defined speed) the starting value can be adapted
to reduce the flying restart time.
4. Set the flying restart current in C00994
.
We recommend setting a flying restart current of 10 % ... 25 % of the rated motor
