High Speed Input Port
The M2DC has 4 optically isolated high speed digital inputs X1, X2, X3, and X4. These inputs allow input
voltage from 5VDC to 24VDC with maximum current of 20mA, and up to 500KHz. They can be used for
general purpose inputs, connecting sensor switch signals, PLC controllers or other types of controller
output signals.
NOTE: When the drive is in position mode, X1, X2 can ONLY be set as STEP/DIR signal.
When the drive is NOT in position mode, X1, X2 can be set as general purpose signals.
