Meeting UL Installation
Standards for the Linear
Stage

Linear stage installations must follow UL 1740 - Standard for Safety for Robots
and Robotic Equipment.

Refer to

UL Safety Standards for Linear Stage Installations

on page 24 for a brief

description of this standard.

A Power Enable light 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. See Figure 11 for 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.
