6. They either switch the output terminal to ground or leave it open circuit This is referred to as an open collector output Thus the 57080 input never sees more than 5 volts If you are uncertain about the output voltage of your sensor hook it up to your power supply but not the MS7080MI Measure the voltage with a DC voltmeter at the output terminal in both sensor states and make sure it does not exceed 5 volts If the sensor is truly open collector the voltage will measure 0 in both states Wiring Outputs Before we discuss the output conditions we need to talk about the circuitry All three MS7080MI outputs are optically isolated That means that there is no elec trical connection between the indexer drive and the output terminals The signal is transmitted to the output as light What you see is a transistor NPN type that closes or conducts current when the output is low When the output is high the transistor is open At power up the 57080 sets all three programmable outputs high open circuit The maximum voltage between any pair of and output terminals is 24 volts DC Never connect AC voltages to the 57080 output terminals Maximum current is 100 mA per output inside MS7080MI 3300 1 MS7080MI Optoisolator Controller Chip 52502 or equiv Schematic Diagram of 57080 Output Circuit Since there is no electrical conne
7. ction to the MS7080MI you must provide the source of current and voltage typically from a power supply You must also limit the current to less than 100 mA so that the output transistor is not damaged You would normally use a resistor for this but some loads such as PLC inputs limit the current automatically The diagram below shows how to connect 57080 output to an optically isolated PLC input 12 24 VDC Power Supply MS7080MI OUTPUT 13 Microstepping Most step motor drives offer a choice between full step and half step resolutions In full step mode both motor phases are used all the time Half stepping divides each step into two smaller steps by alternating between both phases on and one phase on Microstepping drives like the MS7080MI precisely control the amount of current each phase at each step position as a means of electronically subdividing the steps even further The MS7080MI offers a choice of 13 step resolutions The highest setting divides each full step into 254 microsteps providing 50 800 steps per revolution when using a 1 8 motor In addition to providing precise positioning and smooth motion microstep drives can be used for motion conversion between different units The 25 400 step rev setting is provided as a means of converting motion from metric to english There 25 4 mm an inch Other settings provide step angles that are decimal degrees 36 000 steps rev makes

9. e wire careful not to reverse the wires DC Power Supply Choosing a Power Supply Voltage Chopper drives like MS7080MI work by switching the voltage to the motor terminals on and off while monitoring current to achieve a precise level of phase current To do this efficiently and silently you ll want to have a power supply with a voltage rating at least five times that of the motor Depending on how fast you want to run the motor you may need even more voltage than that _ you choose unregulated power supply do not exceed 57 volts This is because unregulated supplies are rated at full load current At lesser loads like when the motor s not moving the actual voltage can be up to 1 4 times the rated voltage For smooth quiet operation a lower voltage is better Current The maximum supply current you could ever need is the sum of the two phase currents However you will generally need a lot less than that depending on the motor type voltage speed and load conditions That s because MS7080MI uses switching amplifiers converting a high voltage and low current into lower voltage and higher current The more the power supply voltage exceeds the motor voltage the less current you ll need from the power supply A motor running from 48 volt supply can be expected to draw only half the supply current that it would with a 24 volt supply We recommend the following selection procedure 1 If you plan to use only a f
10. ew drives get a power supply with at least twice the rated phase current of the motor 2 If you are designing for mass production and must minimize cost get power supply with more than twice the rated current of the motor Install the motor in the application and monitor the current coming out of the power supply and into the drive at various motor loads This will tell you how much current you really need so you can design in a lower cost power supply If you plan to use a regulated power supply you may encounter a problem with current fold back When you first power up your drive the full current of both motor phases will be drawn for a few milliseconds while the stator field is being established After that the amplifiers start chopping and much less current is drawn from the power supply If your power supply thinks this initial surge is a short circuit it may fold back to a lower voltage Because of that unregulated power supplies are better They are also less expensive Connecting the Motor Never connect the motor to the driver when the power is on Secure any unused motor leads Never disconnect the motor while the power is on Never connect motor leads to ground or to a power supply You must now decide how to connect your motor to the drive Red 4 A lead Four lead motors can only be connected A motor one way Please follow the sketch at the Blue Yellow White right B B 4 Leads Six
11. lead motors can be connected in series or center tap In series mode motors produce more torque at low speeds but cannot run as fast as in the center tap configuration In series operation the motor should be operated at 30 less than the rated current to prevent overheating Winding diagrams for both connection methods are shown below Note NC means not connected to anything A Grn Wht a White 6 White NC lead ad motor motor Green A Paa Red YY B NC B B B NC 6 Leads Series Connected 6 Leads Center Tap Connected Eight lead motors can also be connected in two ways series and parallel As with six lead motors series operation gives you more torque at low speeds and less torque at high speeds In series operation the motor should be operated at 30 less than the rated current to prevent overheating The wiring diagrams for eight lead motors are shown below A __ BIk Wht Org Wht 8 lead ne BIk Wht Org motor motor Black Black Yel low Red Red Yellow fw Wht B wre 8 Leads Series Connected 8 Leads Parallel Connected Connecting to the PC Locate your computer within 6 feet of the MS7080MI e Your MS7080MI was shipped with a black adapter plug It has a telephone style jack at one end and larger 9 pin connector at the
