Note
● Do not set start frequency in torque control. Otherwise, larger rush-in current
results at start.
● Reduce setting of A8-11 of the slave in master and slave control but the setting
must be larger than 0.20 Hz. Meanwhile, if deceleration time is very short, in-
crease setting of A8-11 properly. The larger the setting of A8-11 is, the weaker
window effect will be obtained.
Set initial value to half of rated motor slip. You can obtain rated motor slip according to the
following formulas:
Number of pole pairs of motor (take an integer) = (60 x rated motor frequency)/rated motor speed
Synchronous motor speed = (60 x rated motor frequency)/number of pole pairs of motor
Rated motor slip = (synchronous motor speed - rated motor speed)/synchronous motor speed x
rated motor frequency
Flexible connection
For the master in speed control, perform the following settings. Note that only the setting of
F8-15 can be modified.
