when start the zero-gravity
actuator, there is no
counting signal for more
than 2.5 seconds
1.Zero-gravity actuator is
broken
2.zero-gravity actuator wire is
disconnected.
3.the signal wire of
zero-gravity actuator is
disconnected
1.change zero-gravity
actuator
2.check whether the
zero-gravity motor wire is
well connected.
3.check whether the signal
wire of zero-gravity
actuator is well connected
