MYCOM IMS500-120S

Technical Specifications​

Power supply is DC 24 V ±10 percent. Drive method is star-bipolar five-phase output. Maximum output current is 1.4 A per phase. Resolution supports full and half step; basic step angle depends on the connected five-phase motor and is 0.72 degree or 0.36 degree. Control inputs are photoelectric coupler inputs with 220 ohm input resistance. Input signal levels are L 0 to 0.5 V and H 4 to 5 V. CW terminal accepts pulse commands; CCW terminal accepts direction commands in single-pulse mode or reverse/forward pulses in double-pulse mode; CO terminal controls excitation on/off with H level excitation-off and L level excitation-on. Auto current-down and output-current-off functions are provided.

Functional Features​

Ultra-compact body, selectable excitation mode, selectable pulse input mode, automatic current reduction at standstill or no-pulse conditions, and photoelectric isolation between control signals and power stage.

Applications​

Small CNC stages, semiconductor handling equipment, laboratory instrumentation, valve and damper positioning, packaging machines, and industrial fixtures requiring low-vibration five-phase motion.

Construction And Materials​

Driver body dimensions are 67.0 mm × 60.0 mm × 24.6 mm. Driver mass is approximately 75 g. The unit uses a printed circuit board, power semiconductor stage, heat-conductive baseplate/heatsink area, photoelectric input circuit and screw or plug terminals according to the ordered set.

Working Principle​

The controller sends CW/CCW pulses and CO enable signals. The driver converts these into sequenced five-phase stator currents through the star-bipolar bridge, produces microstepping or full/half steps according to the resolution setting, and automatically lowers current when the motor is static to reduce heat.

Installation Requirements​

Mount the driver in a clean, ventilated control panel with clearance for heat dissipation. Use stabilized DC 24 V ±10 percent with adequate current margin for all phases. Separate motor cables from signal cables. Connect motor phase windings only to MYCOM-compatible five-phase motors rated for the 120-class current. Set excitation and pulse mode before energizing.

Precautions​

Do not exceed 1.4 A per phase. Verify motor step angle and winding type before configuration. Maintain ambient temperature 0 to 40 °C and humidity below 80 percent without condensation or freezing. Keep storage temperature -10 to 60 °C. Confirm insulation resistance above 100 MΩ at DC 500 V between power/motor terminals and heatsink/signal terminals before return-to-service. Avoid cable routing that exposes low-voltage signal inputs to noise or high-voltage transient.
