Ministep power stages for two-phase stepper motors The power stages type MSX are used for bipolar control of two-phase stepper motors with phytron’s welltried technology, now with enhanced 4 quadrant chopper type current control. Run and stop current can be set by rotary switches. Overdrive, Boost, Activation and Motor direction are activated by DIP switches. - Page 6 Fig. 2: Front view without panel Motor currents from 4.4 to 15.4 A Peak Run and stop current can be individually set by rotary switches. The MSX automatically changes to the stop current, if there aren’t any control pulse signals. The Boost current (130 % of the preset run current) can either be activated by the input Boost or is permanently switched on by DIP switch.
- Page 7 Manual MSX MINI Inputs The inputs of the power stages MSX can be controlled with 5 V or 24 V input level via optocouplers. The inputs Control pulse , Motor direction, Boost and Activation are designed for Open- Collector controlling. The inputs are optically insulated from the MSX power supply voltage.

6 Motor Connection The following chapter describes how to wire different types of Two-phase stepper motors. MSX stepper motor power stages may be connected to stepper motors with 1.1 to 15.4 A phase current. Peak The stepper motor winding resistance should be less than 10 Ohm for full power. -
Page 25: Shielding
Manual MSX MINI 6.1 Shielding To avoid disturbances affecting the wires and instruments installed close to the drive system, we recommend to use shielded cables. The power supply unit in which the MSX is built-in and the motor should be connected to ground by a central earthing tab. -

Page 27: Motor Cable
Manual MSX MINI 6.3 Motor Cable We recommend to wire the stepper motor with a 5-lead cable with shielding mesh. For optimum electromagnetic compatibility (EMC), the cable should not be interrupted by additional connectors or screw terminals.

Page 31: Inputs
Manual MSX MINI 8 Inputs The control inputs Control pulse , Motor direction, Boost , Activation and Reset are electrically insulated by optocoupler from the MSX supply voltage (+U ). This assures best noise suppression between control and power circuit. The signals are active, when current flows through the optocoupler. -
Page 32: Control Pulse Input
Input Control pulse Maximum step frequency: 500 kHz Minimum pulse width: 1 µs A negative control pulse of 1 µs causes a motor step. The step is done with the falling flank of the control pulse and the current is changed from run to stop current. If the time between two control pulses is more than 40 ms, the stop current is activated. -
Page 33: Boost Input
Manual MSX MINI Input Boost If the input optocoupler is energized the MSX changes Boost current. The power stage increases the run and stop current by 30%. Thus, a higher torque can be reached during the acceleration and deceleration time of the motor by changing to boost current. - Page 34 Jumper position Jumper position Reset: Activation: Fig. 15: Board with J1 jumper The power stage is set to a defined initial state with Reset =0 (low active), that means that all error messages and the ring counter are reset. Then, the ring counter is in basic position.

Manual MSX MINI Appendix A: Technical Details A stepper motor can be used with different step resolutions, which are described in the first part of this chapter. The functions Boost, Overdrive, Current Shaping CS and Current Optimization BLOW UP you’ll find in the second part. A1 FULL STEP / HALF STEP / MINISTEP FULL STEP The FULL STEP mode is the operating mode in which a 200-step motor, for example,... - Page 38 HALF STEP The motor step resolution can be electronically multiplied by 2 by alternately energizing the stepper motor’s phases 1, 1+2, 2 etc.. This is the HALF STEP mode. The torque, however, is reduced in the half step mode, compared to the full step mode.

Page 44: A4 Current Shaping Cs
A4 Current Shaping CS Current Shaping (CS) is a circuitry method for delivering a true phase current which corresponds for a wide range of frequencies to a selected current shape (CS= 4 quadrant current regulation). If the stepper motor is driven without CS, the true current differs from the specified current, even in the lower speed frequencies. -
Page 45: A5 Optimization Of The Current Shape - Blow Up
Manual MSX MINI A5 Optimization of the Current Shape - BLOW UP For an ideal stepper motor the holding torque is a true sine wave. In practice, the torque curve more or less differs from this ideal shape. Therefore the MSX offers the possibility to select a current shape as shown in figure 24. In function of the motor used, it is possible to increase the motor performance during run and acceleration. -
