Installation & Wiring Notes

Install the MR-J3-100BS4 in a clean, ventilated control panel. Connect the three-phase 200-230V AC power supply. Utilize the digital I/O for limit switches and control signals, and the analog or pulse inputs for command references. Ensure the cooling fan has adequate airflow and is not obstructed. The operating environment must stay within the specified temperature and humidity ranges.

Expert FAQs

When would I use analog input vs. pulse train input?
Use analog input for speed or torque commands from a potentiometer or analog controller. Use pulse train input for precise position control from a PLC or motion controller's high-speed output.

What does the "BS4" suffix indicate?
The "BS4" suffix typically denotes a specific model variant within the 200V class series, possibly with enhanced I/O capabilities or a particular communication option.

Is forced air cooling noisy?
It produces some audible fan noise, which is standard for actively cooled drives. This is generally acceptable in industrial environments but should be considered for quiet applications.

Can the digital I/O be used for safety functions?
The standard I/O is for control, not safety. For functional safety (like STO), a dedicated safety-rated model or external safety relay is required.

Is this drive good for a machine with many sensors and actuators?
Yes, its integrated digital and analog I/O can help reduce the need for additional external interface modules, simplifying the control system design.
