Description
Servo Amplifier TZ877x ASSY for Mitsubishi CR2D Controller
The TZ877x ASSY is the servo amplifier module (assembly) for the Mitsubishi CR2D controller. This module comprises the complete power electronics for driving the servo motors of the robot axes. Compared to the older RZ series, the TZ series offers improved efficiency and a more compact design. The card generates the three-phase motor currents from the DC link voltage and monitors current, temperature and motor status in the process.
