The hardwired E-STOP ensures that you can
disconnect the drive under all conditions. The
contacts controlled by a DCS or AutoMax digital
output allow you to disable the drive in the event

by the application software.

Fasten the field wires from the drive fault inputs to
the terminal strip. This signal is used to notify the
module that a problem has developed in the
servo. It must be connected if available. Typical
field connections are shown in figure 3.8. Be sure
to use the proper connections for your servo
amplifier.
