HB860H 2-phase Hybrid Servo Drive

Transcription

1 HB860H 2-phase Hybrid Servo Drive 20-70VAC or VDC, 8.2A Peak No Tuig, Nulls loss of Sychroizatio Closed-loop, elimiates loss of sychroizatio Broader operatig rage higher torque ad higher speed Reduced motor heatig ad more efficiet Smooth motio ad super-low motor oise Do ot eed a high torque margi No Tuig ad always stable Fast respose, o delay ad almost o settle time High torque at startig ad low speed, high stiffess at stadstill Lower cost Descriptios The HB series offers a alterative for applicatios requirig high performace ad high reliability whe the servo was the oly choice, while it remais cost-effective. The system icludes a 2-phase stepper motor combied with a fully digital, high performace drive ad a iteral ecoder which is used to close the positio, velocity ad curret loops i real time, just like servo systems. It combies the best of servo ad stepper motor techologies, ad delivers uique capabilities ad ehacemets over both, while at a fractio of the cost of a servo system. Applicatios The HB series offers a alterative for applicatios requirig high performace ad high reliability whe the servo was the oly choice, while it remais cost-effective. Its great feature of fast respose ad o hutig make it ideal for applicatios such as bodig ad visio systems i which rapid motios with a short distace are required ad hutig would be a problem. Ad it is ideal for applicatios where the equipmet uses a belt-drive mechaism or otherwise has low rigidity ad you do't wat it to vibrate whe stoppig.

Whe drive protectio is activated, the red LED bliks periodicity to idicate the error type Priority Time(s) of Blik Sequece wave of RED LED Descriptio 5S 1st 1 0.2S Over-curret protectio 5S 2d 2 0.3S 0.2S Over-voltage protectio 5S 3rd 7 0.3S 0.2S Positio Followig Error Coectors ad Pi Assigmet The HB860H has four coectors, coector for cotrol sigals coectios, coector for stator sigal coectios, coector for ecoder feedback ad coector for power ad motor coectios. Cotrol Sigal Coector Screw Termial Pi Name I/O Descriptio 1 PUL+ I 2 PUL- I 3 DIR+ I 4 DIR- I 5 ENA+ I 6 ENA- I Pulse sigal: I sigle pulse (pulse/directio) mode, this iput represets pulse sigal, each risig or fallig edge active (software cofigurable, see hybrid servo software operatioal maual for more detail); I double pulse mode (software cofigurable), this iput represets clockwise (CW) pulse, active both at high level ad low level. 4-5V whe PUL-HIGH, 0-0.5V whe PUL-LOW. For reliable respose, pulse width should be loger tha 10μs. Series coect resistors for curret-limitig whe +12V or +24V used. The same as DIR ad ENA sigal. Directio Sigal: I sigle-pulse mode, this sigal has low/high voltage levels, represetig two directios of motor rotatio. I double-pulse mode (software cofigurable), this sigal is couter-clock (CCW) pulse, active both at high level ad low level. For reliable motio respose, DIR sigal should be ahead of PUL sigal by 5μs at least. 4-5V whe DIR-HIGH, 0-0.5V whe DIR-LOW. Please ote that rotatio directio is also related to motor-driver wirig match. Exchagig the coectio of two wires for a coil to the driver will reverse motio directio. The directio sigal s polarity is software cofigurable. Eable sigal: This sigal is used for eablig/disablig the driver. I default, high level (NPN cotrol sigal) for eablig the driver ad low level for disablig the driver. Usually left UNCONNECTED (ENABLED). Please ote that PNP ad Differetial cotrol sigals are o the cotrary, amely Low level for eablig. The active level of ENA sigal is software cofigurable.

This port ca sik or source 20mA curret at 24V. The resistace betwee Ped+ ad Ped- is active at high impedace. 3 ALM+ O 5 ALM- O Alarm Sigal: OC output sigal, active whe oe of the followig protectio is activated: over-voltage, over curret ad positio followig error. This port ca sik or source 20mA curret at 24V. I default, the resistace betwee ALM+ ad ALM- is low impedace i ormal operatio ad become high whe HBS86 goes ito error. The active level of alarm sigal is software cofigurable. See Hybrid servo software operatioal maual for more detail.

6 Curret Cotrol The motor curret will be adjusted automatically regardig to the load or the stator-rotor relatioship. However, the user ca also cofigure the curret i the tuig software. The cofigurable parameters iclude close-loop curret, holdig curret, ecoder resolutio, micro step ad etc. There are also PID parameters for the motor but they have bee tued accordig to Leadshie matchig motor so the user does ot eed to tue them.
