9 Safe Disable Input Function

EN 42 YASKAWA Europe TOEP C710616 88A - AC Drive A1000 IP23/54 Floor Standing - Quick Start Guide

 Safe Disable Monitor Output Function and Digital Operator Display

The table below explains the drive output and Safe Disable monitor state depending on the Safe Disable inputs.

Safe Disable Status Monitor

With the Safe Disable monitor output (terminals DM+ and DM-), the drive provides a safety status feedback signal. This

signal should be read by the device that controls the Safe Disable inputs (PLC or a safety relay) in order to prohibit

leaving the “Safe Torque Off” status in case the safety circuit malfunctions. Refer to the instruction manual of the safety

device for details on this function.

Digital Operator Display

When both Safe Disable inputs are open, Hbb will flash in the digital operator display.

Should only one of the Safe Disable channels be on while the other is off, HbbF will flash in the display to indicate that

there is a problem in the safety circuit or in the drive. This display should not appear under normal conditions if the Safe

Disable circuit is utilized properly. Refer to General Fault and Alarms on page 34 to resolve possible errors.
