Page 3: Introduction
SR4-Plus User Manual 1 Introduction Thank you for selecting the MOONS’ SR4-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. -

Page 6: Connecting To The Inputs
3.3 Connecting to the Inputs 3.3.1 High Speed Digital Inputs The SR4-Plus drives include two high-speed inputs called STEP and DIR. 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 &... -
Page 7: The Enable (En) Digital Input
SR4-Plus User Manual 3.3.2 The Enable (EN) Digital 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. -
Page 8: Programmable Output
SR4-Plus User Manual 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. The output can be wired to sink or source current. When drive is working normally, the output is open. When the drive encounters an error, the output closes. -

Step Noise Filter 4.1 Running Current The output current of the SR4-Plus Step Drive is set by the SW1, SW2, and SW3 switches and can be changed as necessary. There are 8 settings available according to the ON/OFF combina- tion of the switches. -
Page 10: Microstepping
SR4-Plus User Manual 4.3 Microstepping The microstep resolution is set by the SW5, SW6, SW7 and SW8 switches. There are 16 settings. Microstep(steps/rev) 1600 3200 6400 12800 25600 1000 2000 4000 5000 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 1rps. -
Page 11: Step Smoothing Filter
Switch SW11 selects the load inertia. Set it to ON for high inertia applications and to OFF for low inertia applications. The load inertia selection can help the SR4-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. -
Page 12: Motor Selection
Each position of the 16-bit rotary switch selects a different motor, and automatically sets the configuration parameters in the drive. The SR4-Plus drive comes programmed with up to 8 typi- motors as factory defaults. Drives can be customized with specially selected motors when required. -
