If you strike a limit while jogging in the direction of the limit, the Stagehand will immediately stop the motor. If
you strike a forward limit while jogging forward you will have to release the forward jog button and then jog in
reverse. If you strike a reverse limit while jogging reverse you will have to release the reverse jog button and
then jog forward. If you strike an ultimate limit, you will have to physically clear the limit switch before
restarting motion in either direction.
Understanding
the
Status
Display
The two‐line alphanumeric display on the Stagehand Pro (which is the brain of the Mini
2
) motion controller uses
OLED technology to make it easy to read backstage without a distracting backlight. It also has excellent viewing
angles making it easier for you and other operators to see status information at a glance. The Stagehand is
primarily used through our Spikemark software, but it is handy to have some bits of information displayed on
the Stagehand’s faceplate for those times that you are working onstage near the machinery and not sitting in
front of a computer running Spikemark. Also during shop setup, load‐in, and strike you may not have Spikemark
running and need to manually operate the Stagehand. The following list explains the information that you can
glean from the Stagehand display.
Network
Connectivity
Figure 19
When sitting idle, the Stagehand will display its IP address on the bottom line and whether the Stagehand is
actively connected to Spikemark.
Connected
means that the Stagehand has an active connection with a
Spikemark computer,
Disconnected
means that the Stagehand is not actively communicating with Spikemark.
Encoder
Position
Figure 20
If you press either the Forward or Reverse jog button, the Stagehand will display the direction it is traveling and
current speed as a percentage of full power on the top line. On the bottom line it will display the Position
Encoder’s counter in raw encoder counts. Inside Spikemark the position data will be shown in scaled units, such
as feet or inches, but on the Stagehand the raw encoder counts are displayed since the Stagehand isn’t aware of
Spikemark’s Position Scale. The position information is helpful when testing equipment in the shop prior to
load‐in. You can use a Stagehand to power up a machine and confirm that the encoder is working properly by
watching the counts increase and decrease when running forward and reverse respectively. If counts decrease
when running forward you know that the motor and encoder polarity are mismatched and should be rewired
before attempting to run cues.
