Speed control setting (A090~A093)
(1) It is possible when the control mode(F012) setting is over 5.
(2) It is possible to set loop gain, loop constant, proportion gain and integral gain in the speed
control.

(3) A090,
A092
:
If the frequency can’t reach the setting frequency in the acceleration / deceleration time
setting value, make a value of the A090 and A092 lager, and, if a vibration is occured, make a
value of the A090 and A092 lager.
(4) A091,A093
:
If an over-voltage or a speed over-shoot is occurred, make a value of the A091 and A093
smaller.
If you want to shot a deceleration time using the BRD, make a value of the A091 and A093
lager.
