Description
Select the monitor output to
terminal CA.
The setting value of "9" is available
only for the 01800 or more.
Set the full-scale value to output
the output frequency monitor
value to terminal CA and AM.
Set the full-scale value to output
the output current monitor value
to terminal CA and AM.
* The setting depends on the
inverter capacity:
(01160 or less/01800 or more)
Select the monitor output to
terminal AM.
The setting value of "9" is available
only for the 01800 or more.
Set the output filter of terminal AM.
Adjust response level of current
output.
The coasting time is as follows:
00038 or less:...................... 0.5s,
00052–00170: ........................ 1s,
00250–01160: ..................... 3.0s,
01800 or more:..................... 5.0s
Set the waiting time for inverter-
triggered restart after an instanta-
neous power failure.
* The setting depends on the
inverter capacity:
(01160 or less/01800 or more)
No restart
Set a voltage starting time at
restart.
With frequency search
Without frequency search
(Reduced voltage system)
Frequency search at every start
Reduced voltage system at every
start
Set a voltage starting time at
restart.
Consider according to the magni-
tude of load (inertia moment/
torque).
Consider the rated inverter current
as 100% and set the stall preven-
tion 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.

eration time to
