Set the waiting time for inverter-
triggered restart after an instanta-
neous power failure.
No restart
Set a voltage starting time at
restart.
With frequency search
Without frequency search
(reduced voltage system)
Encoder detection frequency

Frequency search at every start
Reduced voltage system at every
start
Encoder detection frequency

Set a voltage starting time at
restart.
Consider using these parameters
according to the load (inertia
moment, torque) magnitude.
Consider the rated inverter cur-
rent according to the overload
capacity as 100% and set the stall
prevention operation level during
restart operation.
Without rotation direction
detection
With rotation direction detection
When Pr. 78 = "0", the rotation
direction is detected.
When Pr. 78 = "1","2", the rotation
direction is not detected.
Set the acceleration time to reach
the set frequency at a restart.
Acceleration time for restart is the
normal acceleration time (e.g.
Pr. 7) when "9999" is set.
