Meeting UL Installation

Standards

Multi-axis stage installations should follow Underwriters Laboratories standard
UL 1740 - Standard for Safety for Robots and Robotic Equipment.

Refer to

UL Safety Standards for Linear Stage Installations

on

page 26

for a brief

description of this standard.

A Power Enable light that illuminates when drive power is applied and motion is
possible.

Emergency movement must be possible when drive power is not available to a ball
screw linear drive with a brake. The figure depicts an operator controlled circuit
for a Kinetix 6000 drive that applies emergency power to release the brake.

ATTENTION: UL 1740 requires all linear stage installations be
equipped as described below.

The design, operation, and verification of this implementation is
the machine builders responsibility.
