We hope our commitment to performance, 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, microstep resolution and other parameters are switch selectable 1.2 Features Power Supply-operates from a 12 to 48 volt DC power supply Output Power-switch selectable, 8 settings, maximum 2.2 amps peak Current Control-advanced digital current control provides excellent high speed torque Microstep Resolution -switch selectable, 16 settings: 200, 400, 800, 1600, 3200, 6400, 12800,25600,1000,2000,4000,5000,8000,10000,20000,25000 step/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- resonance gain settings Microstep Emulation- performs high resolution stepping by synthesizing coarse steps into fine micro-steps Protection -SR2-Plus drive has Over-Voltage, Under-Voltage, Over-Current, Motor-Short (Phase to Phase, Phase to Ground), Over-Temperature and Motor-Open protection features Control Modes- Step Direction or CW/CCW pulse Input Digital Filters-150 kHz or 2 MHz digital filter for high speed inputs Idle Current- switch selectable for 50% or 90% 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 Signal Smoothing-switch selectable, firmware configurable filtering removes spectral components from the command sequence, reducing jerk, limiting excitation of system resonance Rev: 1.0 5/14/2012 SR2-Plus User manual M。ONs 1.3 Block diagram SR2-Plus Block Diagram 12-48VDC Power Supply switching eg Smoothing Filter Load Inertia Step Noise Filter Current set Current set 2 Current set 3 3.3V dle Current Voltage Step Res 1 Det Step Res 2 Step Res 3 Step Res 4 Gate MOSFETS Drivers motor DSP STEP Optical Over DIR Isolation Current EN Input Det ED 2 Mounting the Drive The sr2-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 5/14/2012 SR2-Plus User manual M。ONs 3 Connections To use the SR2-Plus Step Drive, the following items are needed A power supply(12-48 VDC) Pulse Direction signal A compatible step motor 3.1 Connector Diagram LED OUT OUT Control SignalEN DIR STEP COM+ SW8 SW6 Switches for selecting SW5 SW3 SW2 Switches for selecting Sw11 SW9 Motor Connector+ Power Connector V- rounding 3.2 Connecting to the Power Supply If the power supply does not have a fuse on the output or some kind of short circuit current limiting device, a fast acting fuse is required. a 3 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+.

The maximum voltage that can be applied to the input is 28V The motor executes one step with the falling edge of the StEP signal The direction of rotation is controlled by the dir signal level. a high level signal (High Level)will result in clockwise rotation, and a low level signal (Low Level)will result in counterclockwise rota tion 3.4.2 EN input The EN input enables or disables the drive amplifier. It is an optically isolated input that accepts a 5 to 24 volt single-ended(sinking output) signals. The maximum voltage that can be applied to the input is 28V When En input is closed, the drive amplifier is deactivated. all the MOSFE Ts 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 5-24V COM+ Controller STEP STEP with SR2-Plus Sinking DIR outputs EN EN Rev. 1.0 5/14/2012 SR2-Plus User manual M。ONs 3.4.3 Fault Output The FaULT Output is optically isolated. The maximum collector current is 100mA, and the maximum collector to emitter voltage is 30 volts.

There are 8 settings available according to the ON/OFF combination of the switches Peak SW1 SW2 SW3 0.3A ON ON ON 0.5A OFF ON ON 0.7A ON OFF ON SR2-PlUs 0.3A 05A 10A 10A OFF OFF ON SW1 1.3A ON ON OFF SW2 SW3 1.3A 1.9A 1.6A OFF ON OFF 1.9A ON OFF OFF 2.2A OFF OFF OFF 4. dle current The running current of the SR2-Plus drive is automatically reduced whenever the motor hasnt moved for 1 second. Setting the sw4 switch to on reduces the current to 50%of its running value Setting this switch to OFF maintains 90% of the running current. This 90% setting is useful when a high holding torque is required to minimize motor and drive heating it is 日 4 highly recommended that the idle current reduction feature be set to 50% ON OFF unless the application requires the higher setting 50% 90% Rev. 1.0 5/14/2012 SR2-Plus User manual M。ONs 4.3 Microstepping The microstep resolution is set by the Sw5, Sw6, sW7, and sw8 switches. There are 16 settings Microstep(step/rev) SW5 SW6 SW7 SW8 200 ON ON ON ON 400 OFF ON ON ON 800 ON OFF ON ON 1600 OFF OFF ON ON 3200 ON ON OFF ON 6400 OFF ON OFF ON 12800 ON OFF OFF ON 25600 OFF OFF OFF ON 1000 ON ON ON OFF 2000 OFF ON ON OFF 4000 ON OFF ON OFF 5000 OFF OFF ON OFF 8000 ON ON OFF OFF 10000 OFF OFF OFF 20000 ON OFF OFF OFF 25000 OFF OFF OFF OFF 200 400 800 1600 OFF OFF ON ON ON 567 5678 56 3200 6400 12800 25600 SW5 SW6 SW7 5678 SW8 1000 2000 4000 5000 OFFI ON 5678 678 8000 10000 20000 25000 4.4 Self test Setting switch sw9 to on after the drive is powered up will cause the drive to perform a self test move of 2 revolutions both cw and ccw at irps Setting switch SW9 to OFF will disable this feature 9 ON OFF SELF TEST Rev: 1.0 5/14/2012 SR2-Plus User manual M。ONs 4.5 Command Signal Smoothing Setting switch SW10 to ON selects this function; setting it to OFF will disable it Command signal smoothing can soften the effect of immediate changes in velocity and direction, making the motion of the motor less jerky. An added 日 advantage is that it reduces wear on mechanical components This function can cause a short delay in following the control signal, and should be used on OFF with that in mind Command signa Smoothing 4.6 Load Inertia Switch SW11 selects the load inertia. Set it to On for high inertia 日 applications and to oFF for low inertia applications. The load inertia selection can help the sR2-Plus drive to calculate the current control parameter, which is used in Anti-Resonance. If the load inertia is close to that of the motor rotor, select the low(OFF)setting. If the load inertia is ON OFF higher than that of the motor rotor, select the high(ON) setting High LoW Load inertia 4.7 Digital Signal Filter Switch SW12 sets the digital signal filter. The StEP and dir signal inputs have built-in digital filters and this setting will reduce external noise. If the ystem works on the low microstep, select the 150 KHz(ON)setting. If the system works on the high microstep, select the 2 MHZ (OFF)setting ON OFF 150 KHZ 2MHZ Digital Signal Rev. 1.0 5/14/2012 10
