 The AC motor drive will execute the speed tracking only if the output current is greater than the
value set by Pr. 07-09.
 The maximum current of speed tracking will affect the synchronous time. The larger the
parameter setting is, the faster the synchronization arrives. However, if parameter setting is too
large, overload protection function may be activated.
