## **3.5 Amp Bi-polar stepper motor drive MSE570** _**Evo 2**_ 

The MSE570 is a low cost high performance Eurocard Bi-polar drive designed for mounting in 3U high Euro-racks. Ideally suited for use with Nema size 17, 23 & 34 stepper motors, the unit provides a wide range of current options. Designed for use by original equipment manufacturers, the unit provides a reliable and economic in-service proven’ drive solution. Furthermore, the MSE570 design enables users to customise the unit to meet their exact requirements by providing a series of up-grade options which can easily be implemented. 

## **Improved Output stage efficiency** 

The MSE570 _Evo 2_ features a chopped constant current output stage with on-board current settings from 0.5 to 3.5 Amps per phase to meet the requirements of virtually any 2 or 4 phase hybrid stepper motor in the Nema 17, 23 & 34 frame sizes. The use of chopped constant current drive techniques combined with the latest developments in power stage technology results in significant advances in efficiency. Furthermore, the output current may be reduced via an external input when the motor is at standstill to reduce temperature rise in the drive and the motor. The drive is designed for use with rail voltages from 15 to 48 Vdc such as MSE173 when up to 7 drives can be incorporated in a single rack together with the power supply. For high speed operation the  Power supplies type MSE562 & MSE875 are recommended for single and multi axis applications depending on motor current settings. 

## _**New Features**_ 

- Increased efficiency 

- No heatsink required 

- Reduces width 

- Increased operating voltage 

- Single rail supply for both logic and motor 

- Standard Thermal protection & condition monitoring 

## **Choice of full or half step drive** 

The MSE570 may be set to operate in full step or half step drive. Half step drive is recommended since it provides increased resolution ( 400 steps/rev. using conventional hybrid stepper motors ) together with improved smoothness and damping of motor resonance. 

## **Thermal Protection** 

A thermal sensor is fitted to prevent overheating of the output stages. The drive may be automatically disabled on over-temperature by setting switch SW1-1 on. 

## **Status LED’s for condition monitoring** 

|**Status LED’s for condition monitoring**||||
|---|---|---|---|
|The MSE570 drive board has five status LEDs. The|LED 1|Green|Power in on|
|status LEDs provide a visual indication of drive|LED 2|Yellow|Output is disabled|
|condition. The function of each indicator is shown in|LED 3|Red|Over-temperature fault detected|
|the table. Surface-mount types are fitted as|LED 4|Red|Overload fault detected|
|standard, with provision for the user to fit through-|LED 5|Yellow|Home phase output|
|board types. These may be soldered into locations||||
|at the front edge of the board.||||



## **Customising the MSE570 to meet individual application requirements** 

## **Choice of external or internal step control** 

In most applications MSE570 will be operated in conjunction with an external control source consisting of a clock pulse train to determine rate and distance together with a direction signal. Where operation off line from a control processor is required a print on the circuit board is provided for the user to add a simple voltage controlled oscillator to facilitate manual control of the motor drive system.

## **Rack mounting power supply** 

## **MSE562** 

The MSE562 is designed for mounting in a 3U high Eurorack and is ideal for use with the MSE570 drive card. The unit will power up to 2 small motor axes or a single axis using a 34HS size motor. For applications requiring multi-axis operation using a combination of motors requiring high current settings the MSE173 Power supply or MSE875 units are recommended to drive up to 4 motors. 

MSE562 provides a 35 Vdc motor rail for high speed  operation using the MSE570 Evo 2 drive. 

Alternatively, where a motor is to be used at ultra high speed, the MSE562’s 70 Vdc rail can be utilised in conjunction with a PM546 Drive
