• Speed Response Performance for Speed Proportion/
Integration Gain Value
• When Autotuning is not operated well
In case the load rigidity is too low, the gain obtained by autotuning
may not fit well. In such case, set the gain according to the
procedure below.
① First, set the speed integration gain (SEt-03) to non-load gain
value (Factory value as when delivered).
② Raise the speed proportion gain (SEt-02) to the limit where there
is no vibration in the machine part.
③ Raise the speed integration gain (SEt-03) to the limit where the is
no vibration in the machine part.
④ Operate jog operation or start up.
⑤ If there is big vibration or noise in the load, reduce the speed
proportion gain (SEt-02) or speed integration gain (SEt-03).
⑥ Repeat ④ and ⑤ until appropriate operation can be done.
Typically, the system using the belt or chain cannot oper-
ate with fast response performance because of low rigid-
ity of the machine. Set the SEt-06 value to 300 ~ 600.
In case of which the load inertia exceeds 5 times that of
the motor or the load torque exceeds 5 times that of the
motor, it is impossible to expect fast response. In such
case,
Reduce the inertia of the mechanical part and
load torque. Increase the acceleration/deceler-
ation time.
Exchange to motor which gets high motor
inertia.
Select the motor, which the output torque is
higher.
Lower the system response performance.
(Reduce the gain.)
