Mounting and Connecting the MP-Series Integrated Multi-axis Linear Stage Chapter 4
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.
