sR8-Plus User manual M。ONs 1 ntroduction Thank you for selecting the MooNS SR8-Plus Motor Drive. We hope our commitment to perfor- mance, quality and economy will make a successful motion control project 1.1 Overview The SR series drives are cost-effective, high performance 2 phase step drives. The design is based on advanced digital current control technology, and features high torque, low noise, and low vibration. The running current and microstep resolution are switch selectable 1.2 Features Power Supply-operates from a 24 to 75 volt DC power supply Output Power-position switch selectable, 8 settings, max 7.8 amps peak Current Control -advanced digital current control provides excellent high speed torque Microstep Resolution-position switch selectable, 16 settings: 200, 400, 800, 1600, 3200, 6400, 12800,25600,1000,2000,4000,5000,8000,10000,20000,25000step/rev Speed Range- speeds up to 3000 rpm Anti Resonance-raises the system-damping ratio to eliminate midrange instability and allow stable operation throughout the speed range of the motor Auto Setup-measures motor parameters and configures motor current control and anti-reso nance gain settings Microstep Emulation- performs high resolution stepping by synthesizing coarse steps into fine micro-steps Control Modes-Step& Direction or CW/CCW pulse Input Digital Filters-2 MHz digital filter for high speed inputs Motor Type Select-a 16 bit rotary switch is used to select the desired motor database which is pre-loaded at the Factory Load Inertia Select -as part of the motor database each motor can be selected for use with low or high load inertia Idle Current -switch selectable for 50% or 9o% idle running current reduction 1 second after the motor stops Self Test- switch selectable, the drive will perform a 2 rev, 1 rps, CW/CCW move test ReV 1.0 5/10/2012 sR8-Plus User manual M。ONs 1.3 Block diagram SR8-Plus Block Diagram +24t075VDG GND Supply I 5Volt DC Stop Filt Step Res Noise Filter Voltage Currert Level 3 Switch to spl Temo Cuirent Leyel 2 Det Currert leyel 1 MOSFET Amplifie Driver DIR+ Controller O LED 0 Configurations STEP:5-24V) DR(5-24V EN(5-24) 0UT(30,100mA) Step Input Fault Output CW Pulsc CCW Pulsc Reset Fault 2 Mounting the Drive The SR8-Plus Step Drive can be mounted on the wide or the narrow side of the chassis. If it is mounted on the wide side, M3 screws should be used through the four corner holes For narrow side mounting applications, M3 screws can be used in the two side holes The amplifiers in the drive generate heat. To operate the drive continuously at maximum power forced air cooling, as from a fan, should be provided Never use the drive in a space where there is no air flow or where other devices can cause the surrounding air to be more than 40C. Never put the drive where it can get wet or where metal particles can fall into it Rev. 1.0 5/10/2012 sR8-Plus User manual MOOns 3 Connections LE口 To use the SR8-Plus Step Drive, the following items are needed QUT ol signa A power supply(24-75 VDC) Pulse Direction signal STEP+ A compatible step motor Switches forSw'2 Conector 3. 1 Connecting to the Power Supply Grounding If the power supply does not have a fuse on the Screw output or some kind of short circuit current limiting device, a fast acting fuse is required. a 8 amp fast acting fuse should be installed in line with the power supply lead Connect the motor power supply"+"terminal to the drive terminal labeled V+.

They accept 5 to 24 volt single-ended or differential signals, up to 2 MHz. Typiclly these inputs connect to an external controller that provides step direction command signals. You can also connect a master encoder to the high-speed inputs for "following"applications. Or you can use these inputs with Wait Input, If Input, Feed to Sensor, Seek Home and other such commands Connection diagrams follow +5V to +24V out DIR+ Ind with DIR DIR- SR8-Plus sinking outputs STEP+ STEP STEP Connecting to indexer with sinking outputs DIR D|R十 Ind COM DIR- with SR8-Plus sourcIng outputs STEP STEP+ STEP.

It is an optically isolated input that accepts a 5 to 24 volt single-ended or differential signal. The maximum voltage that can be applied to the input is 28V When En input is closed, the driver amplifier is deactivated, all the MosFETs will shut down, and the motor will be free. When en input is open, the drive is activated When the drive has encountered an error and the fault is removed from system, a falling signal into the EN input will reset the error status and activate the drive amplifier again EN+ 5to24 wer Switch Relay SR8-Plus ply EN onnecting the input to a switch or relay 5-24V Indexer oUT EN+ th sourcing SR8-Plus outputs oUT EN Connecting the input to sourcing outputs 24V power supply OUT+ Indexer EN+ sinking SR8-Plus outputs QUT EN Connecting the input to sinking outputs ReV 1.0 5/10/2012 sR8-Plus User manual M。ONs 3.3.3 Programmable Output The FAULT Output is optically isolated. The maximum collector current is 100mA, and the maxi- mum collector to emitter voltage is 30 volts.

There are 8 settings available according to the on/oFF combina tion of the switches Peak SW1 SW2 SW3 2.4A ON ON ON OFFOFF OFF 3.0A OFF ON ON SR8-Plus 3.8A ON OFF ON 4.5A OFF OFF ON SW2 3.0A 3.8A 4.5A 5.6A ON OFF OFF ON 64A OFF ON OFF 56A64A7.0A78A 7.0A ON OFF OFF 7.8A OFF OFF OFF 4.2 dle current The running current of the SRB-Plus drive is automatically reduced anytime the motor isnt mov- ing. Setting the sw4 switch to On reduces the current to 50% of it running value Setting this switch to OFF maintains 90%of the running current. This 90% setting is useful when a high hold ing torque is required. To minimize motor and drive heating it is highly recommended that the idle current reduction feature be set to 50% unless the application requires the higher setting ON OFF 50% 90% ReV 1.0 5/10/2012 sR8-Plus User manual M。ONs 4.3 Microstepping The microstep resolution is set by the Sw5, Sw6, sw7 and sw8 switches.
