Yaskawa MicroTrac DSD Drives System Input - Manual (Page 5)

supply +10.0 Vdc reference, -10.0 VDC
reference, COMMON, and SHIELD tie
points. Each of the references will supply
up to 50 milliamps of current.
Differential Analog Input. There is
provision for one non-isolated differential or
single ended analog input. The input has a
maximum differential range of +/- 10 VDC
or +/-0.5 VDC with an input common mode
voltage range of +/- 10 VDC. The overall
A/D conversion accuracy is +/- 0.4 % with
12 bits of resolution over the full scale
range. The signal names are labeled DIFF
IN (+) and DIFF IN (-).
Connection terminals are provided that will
supply COMMON and SHIELD tie
points. Also see SETUP.
4-20 mA Input. There is provision for one
non-isolated 4-20 mA analog input. The
input signal feeds a differential amplifier
with a maximum of +5 VDC across a 249
ohm burden resistor at the 20 mA level.
The input common mode voltage range is
+/- 10 VDC. The overall A/D conversion
accuracy is +/- 0.4 % with 12 bits of
resolution over the full scale range. The
signal names are labeled CUR. FOL. IN (-)
and CUR. FOL. IN (+).
Connection terminals are provided that will
supply +5 Vdc, COMMON, and SHIELD tie
points.
Analog Output. There is provision for one
non-isolated analog output. The output has
a range of +/- 10 VDC with respect to
common, is single ended, and has an
output drive limited to +/- 4 mA. The D/A
conversion accuracy is +/- 0.4% with 12
bits of resolution over the full scale range.
The signal name is labeled ANOUT1.
Connection terminals are provided that will
supply COMMON and SHIELD tie points.
Relay Contact Outputs. There is provision
for one relay with form C type contacts
being brought to the connector. The
maximum switching voltage is 36
VAC/VDC. The maximum switching
current is 0.5 A. The signal names for the
form C contacts are labeled K1-C, K1-NO,
and K1-NC.
INSTALLATION AND HOOKUP
This board is factory installed in the
drive and should require no further
connections to be made to it. However, if it
should become necessary to install the
board in the field, then the following steps
should be taken:
