Product Introduction

MC556 mini is a digital two-phase hybrid step motor drive designed based on the latest 32-bit DSP control technology. It can help to customize any subdivision within 400~25600 and any current within the rated range and has an additional automatic motor parameter identification function for adopting corresponding running parameters for different motors and making motors run very smoothly with an extremely low noise.The driver can be match for 2 phase Nema23/Nema24 open loop stepper motor.

Drive function description

Drive function	Instructions
Microstep subdivision setting	15 microstep subdivisions can be set for the Driver through 4 dial switches SW5~SW8.The Driver shall be stopped while setting subdivision. See driver panel instruction for microstep subdivision settings.
Output current setting	8 output currents can be set for the Driver through 3 dial switches SW1~SW3. See driver panel instruction for output current settings.
Automatic half flow function	Automatic half current function can be set for the Driver through switch SW4. OFF means that quiescent current is set to half of operating current; ON means that quiescent current and dynamic current are the same. SW4 shall be set as OFF for general use to reduce heat generation of the motor and the driver and to improve reliability. About 0.3s after pulse train stops, current will automatically reduce 50%(actual value 55%) and theoretically, heat generation will reduce 65%.
Signal interface	PUL+ and PUL- are positive and negative terminals of pulse signal control; DIR+ and DIR- are positive and negative terminals of direction signal; ENA+ and ENA- are positive and negative terminals of enable signals.
Motor interface	A+ and A- connect to positive and negative terminals of A phase winding of stepper motor; B+ and B- connect to positive and negative terminals of B phase winding of stepper motor. When A and B phase windings are switched, the Motor direction will be reversed.
Power connector	DC/AC power supply, operation input voltage range: 20～ 50 VDC, 36VDC input voltage is suggested, power supply shall be higher than 100W.
Indicator light	There is 1 green indicator light and 1 red indicator light on the Driver. The green one is power indicator light, it illuminates when the Driver is connected to power supply; the red one is failure indicator light, it illuminates when over-voltage or over-current failure occurs.Red indicator light goes off after failure is eliminated. Failure of the Driver can only be eliminated by re-connecting to power supply and reusing
Installation Notes	Dimensions of the Driver: 86 x 55x20.5mm, installation pitch of holes: 79mm. Both horizontal and vertical installations can be selected (vertical installation is suggested)The Driver shall be installed closely against metal cabinet for heat dissipation.

Parameter setting

Subdivision precision, dynamic and half/full currents can be set for MC556-Mini Driver through 8-bit dial switch as follows:
