Other Motion I/O Connection

The 7340 provides Host +5 V, which is the internal +5 V supply of the host
computer. It is typically used to detect when the host computer is powered
and to shut down external motion system components when the host
computer is turned off or disconnected from the motion accessory.

Caution

The host +5 V signal is limited to <100 mA and should not be used to power any

external devices, except those intended in the host bus monitor circuits on the UMI and
drive products.
