2 Parameters
2.2 List of parameters
Description:
Sets the factor for the search speed for flying restart.
The value influences the rate at which the output frequency is changed during a flying restart . A higher value results
in a longer search time.
Recommendation:
For encoderless vector control and motor cables longer than 200 m, set the factor p1203 >= 300 %.
Caution:
An unfavorable parameter value can result in the motor behaving in an uncontrollable fashion.
For vector control, a value that is too low or too high can cause flying restart to become unstable.
Note:
The parameter factory setting is selected so that standard induction motors that are rotating can be found and
restarted as quickly as possible (fast flying restart).
With this pre-setting, if the motor is not found (e.g. for motors that are accelerated as a result of active loads or with
U/f control and low speeds), we recommend that the search rate is reduced (by increasing p1203).
For the flying restart of a reluctance motor, the minimum search velocity is limited (p1203 >= 50 %).
Description:
Displays the status for checking and monitoring flying restart states in the U/f control mode.
Description:
Display and connector output for the status for checking and monitoring flying restart states in the vector control
mode.
