Connection
The Stagehand Mini
2
requires a 24vdc Emergency Stop signal from a Showstopper to allow any motion signals to
be output to your machine amplifier. Internally, the Stagehand Mini
2
has a redundant, self‐monitoring circuit to
insure that power will be removed from the amplifier enable signal instantly if the 24vdc Emergency Stop signal
is interrupted. However, since the Mini
2
does control power directly to the amplifier (VFD, DC drive, valve
driver, etc.) you must install appropriate safety contactors to interrupt power to your external amplifier. The
external safety contactors that you install in your amplifier enclosure should be signaled by the same
Showstopper that is connected to the Mini so that both devices are controlled by the same Emergency Stop
signal. Here is an example, bear in mind that you must implement the safety circuitry appropriate for your
application.
