Current Limit of Speed Tracking

Settings 20–200%
 The AC motor drive executes speed tracking only if the output current is greater than the value
set in Pr.07-09.
 The maximum current for speed tracking affects the synchronous time. The larger the parameter
setting is, the faster the synchronization occurs. However, if the parameter setting is too large,
the overload protection function may be activated.
