7.1.2
Voltage and Ground Signals
The 12V and 5V contacts provide all of the voltages required by the drive. The two voltages share a common ground
plane to which all of the ground contacts are connected.
7.1.3
Ready LED Output
The drive provides an open-drain driver with 15mA of current sink capability to the Ready LED Output signal. The
cathode of the LED should be connected to this signal. The LED and the current-limiting resistor must be provided by
the enclosure
