Terminals:​ High-current insulated terminals with copper conductors

Structural Features:​ Book-style panel-mount body, front LED and keypad, pulse and analog I/O terminals, modular internal power section, separated signal and power wiring areas.

Working Principle:​ AC input is rectified to a DC bus and inverted into regulated three-phase output by the IGBT stage. The control board receives pulse or analog commands, calculates position, speed and torque setpoints, and corrects output using encoder feedback. Fault monitoring acts on current, voltage, temperature and encoder abnormalities.

Installation Requirements:​ Mount vertically in a control cabinet with top and bottom ventilation space. Supply three-phase 200 VAC to 230 VAC through a dedicated breaker. Separate motor power and encoder/signal cables. Ground the drive and shield encoder cables according to Yaskawa wiring rules.

Usage Notes:​ Use only with 1.5 kW class Yaskawa servo motors supported by the drive firmware. Complete autotuning or manual gain setting before load operation. Verify encoder wiring and pulse polarity before enabling position mode. Inspect cooling paths and terminal tightness periodically.
