Unintended Operating Control (Uoc) Function - Harmony eXLhoist User Manual

Unintended Operating Control (UOC) Function

Overview
The Base Station can manage 3 UOC functions.
These relays have temporization that shall correspond to the decelerating time ramp of the drive.
After this time, the UOC relay will switch OFF to enable the Safe Torque Off (STO according to EN
IEC 61500-5-2) input on the drive.
The UOC function allows the Wireless Remote Control System to get a STOP category 1 according
to EN60204.
Description
A UOC relay is associated to one motion axis (4 motion buttons).
Once a motion button is pressed, the associated UOC relay is switched ON.
When all motion buttons are released, the UOC delay time starts.
The UOC relay is switched OFF after the UOC pre-defined delay.
