3.1.2 Digital inputs

Six independent digital inputs.

Input voltage range: 12-30 V DC (input current not to exceed 50 mA).

Sampling frequency: 8 kHz.

Each digital input is buffered by a TLP280 opto-isolator, allowing the input signal to be
connected with either polarity.

When the MotiFlex e100 is connected to Mint WorkBench, the digital inputs can be
configured using the Digital I/O tool. Alternatively, Mint keywords including RESETINPUT,
ERRORINPUT and STOPINPUT can be used in the command window. The state of these
specially configured digital inputs can then be viewed using the Mint WorkBench Spy
window's Axis tab. The state of all digital inputs can also be viewed using the Spy window's
I/O tab. See the Mint help file for details.
