Knitting machine is widely used in textile industry.It usually adopts external start and analog signal source speed regulation. It can also be controlled by single chip computer or PLC+ text controller.It has high load speed,high starting torque and often stop urgently.
2. Requirements for inverter application
--Low frequency high torque (heavy load on weaving)
--Quick start response
--The motor runs smoothly during operation
--The stop is soft and accurate, without reversing and turning

--It need to remove the motor load before operation,and stop the motor after confirming the direction of operation.If the direction is reversed,exchange any two connection positions of the three-phase output line.
--It is necessary to pay special attention to the slight reversal of the motor when it is stopped. The DC braking parameters and s-curve parameter sets of the frequency inverter can be adjusted properly.Slight inversion can also damage the needle disk of the great round knitting machine.Regular cleaning and maintenance and paying attention to ventilation and cooling.are needed.
