● The AC motor drive executes speed tracking only when 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, the
faster the synchronization occurs. However, if the parameter setting is too large, the overload protection
function may be activated.

2: Speed tracking by minimum output frequency
0
● In PG control mode, the AC motor drive executes the speed tracking function automatically according to the PG
speed when this setting is NOT set to 0.
● Faults include: bb, oc, ov, occ. To restart after oc, ov, occ, you cannot set Pr.07-11 to 0.

● After fault (allowed fault: oc, ov, occ) occurs, the AC motor drive can reset and restart automatically up to 10
times. If Pr.07-11 is set to 0, the drive resets or restarts automatically after faults occur. The drive starts
according to the Pr.07-10 setting after restarting after fault.
● If the number of faults exceeds the Pr.07-11 setting, the drive does not reset and restart until you press RESET
and execute the operation command again.
