3SR8 User Manual M。ONs 1 Introduction Thank you for selecting the MooNS 3SR8 Motor Drive. We hope our commitment to performance, quality and economy will make a successful motion control project 1.1 Overview The 3SR8 series drives are cost-effective, high performance 3 phase step drives. The design is based on PID 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-3 position switch selectable, 8 settings, maximum 7.8 amps peak Current Control-advanced digital current control provides excellent high speed torque Microstep Resolution -3 position switch selectable, 8 settings: 1000, 1600, 2000, 3200, 4000, 5000,6400,51200step/rev Speed Range-speeds up to 1800 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 Control Modes- Step Direction(contact factory for CW/CCW pulse option) Input Digital Filters- 150K Hz or 2M Hz 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 go% 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 9/15/2010 3sR8 User Manual M。ONs 1.3 Block diagram 3SR8 Block Diagram 24-75VDC(3sR8) External Power Supply 33V Voltage Det Gate MOSFETs Drivers motor Rotary code (3 Optical DSP Isolation Over Current Det 8-hit LED 2 Mounting the drive The 3SR8 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 9/15/2010 3SR8 User Manual M。ONs 3 Connections To use the 3sR& Step drive, the following items are needed LED A power supply(24-75 VDC) Rotary switch Pulse Direction signal FAULT+/-厂OT oUT+ A compatible step motor STEP+/DIR+/ENA+/Fdir- STEP Running current,-STEP+ Step resolution, Sw8 Idle current reduction and Self test SW5 3.1 Connecting to the Power Suppl If the power supply does not have a fuse on the Motor Connector HW output or some kind of short circuit current limiting device, a fast acting fuse is required.

They accept 5 to 24 volt single-ended or differential signals, up to 2MHZ. 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 low level signal (0 level) will result in clockwise rotation, and a high level signal (1 level)will result in counterclockwise rotation +5y to +24v out DIR+ indexer 3sR8 DIR DIR- 5-24V Sinkin High Outputs STEP+ Speed STEP STEP- Inputs Connecting to indexer with Sinking outputs DIR DIR+ Indexer 3sR8 with COM DIR- 5-24 Sourcing High Outputs STEP sTeP+ Speed Inputs Connecting to Indexer with Sourcing outputs DIR+ DIR+ Indexer 3sR8 DIR- DIR- 5-24V Differential STEP+ STEP+ High touts Speed STEP STEP- Inputs Connecting to Indexer with Differential Outputs Many high -speed indexers have di Rev 1.0 6 9/15/2010 3SR8 User Manual M。ONs 3.3.2 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 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 5to24 EN+ volt Switch or Relay 3sR8 Power (closed logic low) Drive Supply EN Connecting the Input to a Switch or Rela 5to24 EN+ volt 3sR8 Power NPN Proximity Drive Supply Sensor outpt EN Connecting an NPN type Proximity Sensor to an input (when prox sensor activates, input goes low outpu 5to24 十 PNP EN+ volt Proximity Sensor 3sR8 Power Drive Supply EN (when prox sensor activates, input goes p, an input Connecting an PNP type Proximity Sensor to Rev. 1.0 9/15/2010 3sR8 User manual M。ONs 3.3.3 Fault Output The FAULT Output is optically isolated. The maximum collector current is 100mA, and the maximum collector to emitter voltage is 30 volts. The output can be wired to sink or source current When drive is working normally, the output is open.

There are 8 settings available according to the oN/OFF combination of the switches Peak SW1 SW2 SW3 1.5A ON ON ON 2.0A OFF ON ON 3sR8 3.0A ON OFF ON 4.0A OFF OFF ON SW 5.2A ON ○N OFF SW3 52A5.8A7.0A78A 5.8A OFF ON OFF 7.0A ON OFF OFF 7.8A OFF OFF OFF 4. dle current The running current of the 3SR8 drive is automatically reduced anytime the motor isnt moving for 1S. 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 holding 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 4.3 Microstepping The microstep resolution is set by the SW5, SW6 and sw7 switches.

The 3SR8 drive comes programmed with up to 8 typical motors as factory defaults. Drives can be customized with specially selected motors when required The rotary switch also selects a low or high inertia for each motor to allow for various load conditions. The low setting is 1: 1, and the high setting is 10: 1. Each motor in the loaded database has unique settings to optimize the anti-resonance See the table below When the motor selection is changed the drive power supply will need to be cycled.
