For the purpose of synchronous operation of the Extra-feeding and the Winding
，
please debug on-site the
acceleration and deceleration time of the Extra-feeding motor to make both of them synchronous reliably. Because
the acceleration and deceleration setting time is the needed time that the frequency of the converter operates from 0
Hz to 50Hz or from 50Hz to 0Hz, and that the target frequencies operated of the winding and extra-feeding motors
are frequently different, when debugging the winding motor operating in mode of frequency decrease progressively,
constant velocity and swing frequency, the user should suitably set the acceleration and deceleration time to
guarantee that while the winding motor operates to its target frequency, the extra-feeding motor can achieve its
target frequency at the same time and while the winding motor decreases to 0 Hz, the extra-feeding motor also
decreases to 0Hz simultaneously.

Compensation
Carrier wave frequency is the pulse frequency of the converter’s output PWM wave. The higher the carrier
wave frequency, the lower the electromagnetic noise of the motors; but the wear of converter’s switch and
the temperature rise will increase. The Torque Compensation is mainly to increase the output torque of the
converter at low frequency. The larger the compensation, the larger the torque at start-up, but it will
increase attack to the motors. Therefore the user may set up 5-06 according to the actual situation.
