The UM113D Driver consist of the following modules:
• One UV or UVR power supply unit including the necessary additional components
• Several UM power modules for axes and spindle • Ribbon cables and covers
In modular systems, the power supply unit produces the rectified DC-link voltage. The IGBT full bridges are housed in the separate UM power modules. The DC-link power bar conducts the DC-link voltage to the power modules.
The CC controller unit is connected to the power modules over a ribbon cable and uses PWM signals to control the IGBTs.
The power modules are arranged to the right in order of decreasing power rating.
