Interface connections

Warning! Risk of personal injury or death
A risk of personal injury or death exists if Limit Enable inputs are not properly
connected. Limit Enable inputs are available on the Axis Motor connector and
the Limit Switch connector.
To avoid the hazard use only one pair of Limit Enable inputs per axis. Never use
the Limit Enable inputs from both connectors. If both are used, limit switch
function is severely impaired.
Notice
This product contains components that can be damaged by electrostatic
discharge (ESD). Observe precautions for handling ESD sensitive devices and
never touch connector pins unless properly grounded.
Notice
Do not overtighten interface cable connection screws to avoid damage to the
product.
