5.3.2 General purpose digital input DIN0
Location Connector X3, pins 7 & 19
(Mating connector: Weidmüller Minimate B2L 3.5/24 LH)
Name DIN0
Description General purpose opto-isolated digital input.
Nominal input voltage: 24 VDC
(input current not to exceed 50 mA)
Sampling interval: 1 ms
This general purpose digital input is buffered by a TLP280 opto-isolator, allowing the input signal
to be connected with either polarity. The state of the digital input is displayed in the Mint
WorkBench Spy window. The input can be can be configured for different user definable
functions.

When the MotiFlex
e
100 is connected to Mint WorkBench, the digital input can be configured
using the Digital I/O tool. Alternatively, Mint keywords including RESETINPUT , ERRORINPUT ,
STOPINPUT , FORWARDLIMITINPUT , REVERSELIMITINPUT , POWERREADYINPUT and
HOMEINPUT
can be used in the command window. The state of the digital input can be viewed
using the Mint WorkBench Spy window’s Axis tab. See the Mint help file for details.
5.3.2.1 Using a digital input as a home switch input
When the MotiFlex
e
100 is being controlled over EPL by a manager node (e.g. NextMove
e
100),
the home switch input must be wired to the MotiFlex
e
100, not the manager node. This is because
the manager node only
triggers
the homing sequence, which is then performed entirely by the
MotiFlex
e
100. It is therefore the MotiFlex
e
100 which must receive the home switch input signal,
otherwise it will not be able to complete its homing routine. Similarly, it is the MotiFlex
e
100’s own
HOME
... keyword parameters that define the homing sequence.
