Digital I/O Power
The drive requires an external 12 to 24VDC power source for the inputs and outputs.
External I/O Power
The external I/O power supply must be capable of supplying at least 250 mA.
The pin-outs are:
The external I/O COM must be grounded to meet the European Low Voltage Directive (LVD).
Digital Inputs
OMNIDRIVEs have active high, current sinking inputs, which prevent disconnects and ground faults
from activating a drive. The typical ON time for an input to be rec
Two discrete input circuits types are available on the J1 connector. Both circuits support logic type
interfaces with optically isolated, single ended and active high, current sinking characteristics.
Dedicated Control Circuits
The ENABLE input interfaces with switch closures or sourcing type outputs. The input channel sinks 4.5
mA nominal.
Selectable Circuits
INPUT 1, INPUT 2, INPUT 3 and FAULT RESET operate with switch closures or sourcing type circuitry.
Each input channel sinks 4.5 mA nominal. Selectable inputs are:
