1.4.3.3 V/f Catch on Fly from Running on AC Input
The function allows the Drive to catch an already rotating motor, “Autocapture”.
An automatic restart of the Drive is possible after a “Retrying” temporary alarm condition.
Through the V/f catch cmd src source it is possible to select the origin of the command signal enabling the function.
In the configurations the function can be parameterized according to the application.

V/f catch cfg
Spd search time
It states the change of the Drive output frequency. It shows the
time needed to perform a frequency change from zero to the motor
rated one if the output current is equal to the motor rated one.
Vlt search time
It states the machine flux change. It shows the time needed to
perform a flux change from zero to the motor rated one, if the
output current is equal to the motor rated one.
Catch init speed It states the starting speed for the synchronism search.
Catch demag dly
Delay time for the motor demagnetization before performing the
synchronism search (in case the “autocapture” function is present).
Catch retry dly
Delay time for the motor demagnetization (with the “retrying”
function).
