Digital setting of the torque command can be made
by setting Pr. 805 or Pr. 806. (Setting from
communication option, etc. can be made.)
In this case, set the speed limit value to an
appropriate value to prevent overspeed.

Use the speed command value during speed control
as speed limit.
1
According to Pr. 808 and Pr. 809, set the speed limit in
forward and reverse rotation directions individually.
2
The analog voltage of the terminal 1 input is used to
make speed limit. For 0 to 10V input, set the forward
rotation speed limit. (The reverse rotation speed limit
is Pr. 1 Maximum frequency)
For -10 to 0V input, set the reverse rotation speed
limit. (The forward rotation speed limit is Pr. 1
Maximum frequency.) The maximum frequency of both
the forward and reverse rotations is Pr. 1 Maximum
frequency.
808
Forward rotation speed limit
0.01Hz 60Hz 0 to 120Hz
Set the speed limit level during forward rotation.
(valid when Pr. 807 = 1)
809
Reverse rotation speed limit
0.01Hz 9999
0 to 120Hz
Set the speed limit level during reverse rotation.
(valid when Pr. 807 = 1)
9999
The setting is the same as that of the torque limit in
the forward rotation direction.

The optimum gain is
automatically set from the

820
Speed control P gain 1
1% 60% 0 to 1000%
Set the proportional gain for speed control.
(Increasing the value improves trackability in
response to a speed command change and reduces
speed variation with disturbance.)

Speed control integral time
1
0.001s 0.333s 0 to 20s
Set the integral time during speed control. (Decrease
the value to shorten the time taken for returning to
the original speed if speed variation with disturbance
occurs.)
