11.4 Basic functions
11.4.1 Basic block diagram
The various functions of the power supply module are shown in the following block diagram.
(1) The power supply module converts the AC400V input connected to the main power supply connector
(X102) into a DC power supply by a converter unit consisting of a rectifier circuit and a main power supply
capacitor, and supplies the power required for driving the motor of the driver module connected to the
high-voltage power supply bus bar (X12).
(2) The regenerative processing circuit controls the regenerative power from the driver module to be
consumed by the external regenerative resistor connected to the regenerative resistor connector X103.
(3) Connect the control power supply common to the power supply module and driver module to the control
power supply connector (X11), and supply it to multiple driver modules through the control power supply
bus bar (X104).
(4) Regenerative resistor temperature and contactor feedback input signal can be connected to the external
device input connector (X2).
(5) The contactor control output connector (X101) can control the auxiliary contact of the magnetic contactor
of the main power supply. The main power ON / OFF can be controlled from the EtherCAT object of the
specified driver module connected by EtherCAT communication via inter-module communication.
(6) Inter-module communication (X1) is used to communicate with the driver modules.
(7) The status of the power supply module is indicated by the 2 LEDs on the front panel.
(8) Alarm/warning functions are provided to monitor each part of the power supply module.
