CN032 AC Servo Solution Hardware Manual (for RZ/T2L)
Abstract
This document describes the specifications of the CN032 AC Motor Solution equipped with
the MPU of the RZ/T2L group manufactured by Renesas Electronics. We provide an
environment for evaluating RZ/T2L without the need for customers to prepare their own
hardware.
<<Caution when handling the solution board>>
Don't touch the board while power is supplied because CN032 AC servo solution board
contains high voltage circuits.

5.1 Fault Detection Circuit
The fault detection circuit is used to detect short-circuit protection, under-voltage protection and over
temperature protection by IPM module. The fault signal VFO outputs low level when SC, UV or OT protection
works, which is open drain type. You can protect the motor solution board and motor by monitoring fault
signal VFO and forcing the PWM output to go into the Hi-Z state when the output is low.
