Rockwell Automation VSM500 Integrated Drive/Motor - Manual (Page 34)

7-4 Installing and Operating the VSM500 Integrated Drive/Motor, Version 3.0
7.1 Wiring Function Loss
For the unit to run, you must maintain a signal at the Function Loss input (the
connection between control terminals 7 and 11). If the Function Loss signal is not
present, the unit turns off the power devices and coasts to rest. To restart the unit, you
must restore the Function Loss signal, clear any faults, and reassert the Start
command.
The unit ships from the factory with a jumper between terminals 7 and 11 which
provides the Function Loss signal. The Function Loss input should be wired in series
with the drive’s external interlocks as shown in figure 7.4. In this case, remove the
jumper before making the connections.
Important: Function Loss provides an operational stop. It does not fulfill the
requirements of an emergency stop. Refer to chapter 6 for information
regarding emergency stop requirements.
