Limit Wiring Strategies
Since the Stagehand provides three (3) separate pins that all source 12vdc, one for each limit signal,
you can reduce the wiring in your machine to four (4) wires by using just one of the 12vdc source pins
and three (3) wires for the three limit return signals. Sometimes it is more convenient to wire a pair of
conductors for each switch, other times it may be better to reduce the number of conductors by
sharing a common voltage source. Both options are shown below:
Speed Encoder
A set of quadrature signals used by the Variable Frequency Drive (VFD) to accurately regulate speed.
Unlike the Stagehand Classic controller, the Stagehand Pro 3 requires a motor-mounted encoder for
speed regulation. This same encoder may be wired for both speed and position data, but only if that
encoder is mounted on the motor prior to the speed reducer. If the VFD detects that the Speed
