bit 10000 Control Power Active
This bit indicates the AriesCE is in keep alive. It is on when only logic power is on (voltage on C1/C2). This bit turns off when amplifier power is on (L1/L2) (immediately).
So in recovering from an estop, you can inhibit until this bit is off.
If monitoring this bit in the event that the AC power is turned off, use a discrete input as well; it takes a few seconds for the motor and amplifier circuitry to dissipate and so it takes a few seconds for this bit 10000 to turn on.
