4-6 Input / Output MN1901
4.2.3 Analog outputs, bipolar - X4
Location Connector X4
Pins 4 5
Name AOUT0 AOUT1
Mint keyword
AUXDAC.0 AUXDAC.1
Description Two independent assignable outputs.
Output range: ±10VDC.
Resolution: 8-bit with sign (accuracy ±78mV).
Output current: 1mA maximum.
Update interval:
Immediate - Software (Mint programs)
1ms, 2ms - DAC monitoring
The two programmable analog outputs can be used to provide the status of various control
conditions. DAC monitoring is the process where the value of a selected parameter can be
monitored by the MintDrive
II
, and the analog output used to produce a voltage proportional to
the value. DAC monitoring can be controlled by various Mint keywords. These begin with the
letters
DACMONITOR
..., for example
DACMONITORMODE
. The update interval for DAC
monitoring is affected by the Mint LOOPTIME keyword. See the Mint help file for details.

, or during firmware download, the analog
outputs may swing to +2V for a period of about 0.25s, before settling at 0V.
