1, control means choice controls need terminal control to regard a command as the source with VF, terminal of second line type controls: Need to turning only command FWD (COM-FWD is inputted) frequency source is controlled by PLC. Top moving rotate speed is in commonly 24000r/min, the running frequency of conversion transducer is 400Hz (the high speed electric machinery of 2 class) , cutting rotate speed of lowest is 2000r/min, the satisfaction with the blame OK and very good label that we use 650Hz its ask. Quicken and slowdown time basis client oneself demand, be in commonly 20 ～ 30s, compare because of the rotate speed that move tall, so need is added hold unit of exterior apply the brake, signal of output of need fault signal and breakdown restoration signal (RST, TA-TC is inputted) . 2, wave motion of the speed inside the limits of performance demand total rate of engraving tool is small, low speed moment of force is large, can assure cutting of low rotate speed, the time that increases decelerate as far as possible short. Debug a result to look from what flying crane engraving tool fetterses, cutting rotate speed of lowest can be under 500r/min. Transducer can be done multistage VF curve, the OK and very good different torsion that controls high low speed promotes, accordingly the requirement on engraving tool of can very good contented high speed. Debug parameter specificly (in the light of rated frequency 400Hz, rated voltage 380V, 24000) of rated rotate speed: F067=1 V/F controls F039=2. 0 terminal command passageway F040=8.
F027=400 of 08 clavier control is the biggest group of F052-F053 of frequency of frequency F015=400 upper limit (electric machinery parameter) , according to input of nameplate of high speed electric machinery. F019=100 dot moves frequency F020=10 dot to move frequency to increase slowdown time CNC Milling
