General Purpose / Status Digital Output Dout0 - Baldor MotiFlex e100 Installation Manual

5.3.6 General purpose / status digital output DOUT0

1
The optically isolated general purpose / status output is designed to source current from the user
supply as shown in Figure 54. The TLP 127 has a maximum power dissipation of 150 mW at
25 °C. The maximum saturated voltage across the outputs when active is 1.0 VDC, so it can be
used as a TTL compatible output.
The output includes a self-resetting fuse that operates at approximately 200 mA. The fuse may
take up to 20 seconds to reset after the load has been removed. If the output is used to directly
drive a relay, a suitably rated diode must be fitted across the relay coil, observing the correct
polarity. This is to protect the output from the back-EMF generated by the relay coil when it is
de-energized. The sense of the output can be configured in Mint WorkBench, and its state is
displayed in the Spy window.

[Error]
By default, DOUT0 is configured as an error status output, which becomes inactive in the event
of an error. When the MotiFlex e100 is connected to Mint WorkBench, the active level of the
output can be configured using the Digital I/O tool. Alternatively, the Mint keyword
OUTPUTACTIVELEVEL can be used in the command window. Other Mint keywords such as
COMPAREOUTPUT, GLOBALERROROUTPUT, DRIVEENABLEOUTPUT and MOTORBRAKEOUTPUT
(see section 3.7.6) can also be used in the command window. The state of the digital output can
be viewed using the Mint WorkBench Spy window's Axis tab. See the Mint help file for details.
