Analog Reference Input
The analog reference input AIN1+ and AIN1- (IOD-24 and IOD-25) accepts
up to a ±10V DC analog signal as shown in Table 12
. The analog signal is
converted to a digital value with 12 bit resolution (11-bit plus sign). The total
reference voltage as seen by the drive is the voltage difference between AIN1+
and AIN1-. If used in Single-ended mode, one of the inputs must be connected to
a voltage source while the other one must be connected to Analog Common
(ACOM). If used in Differential mode, the voltage source is connected across
AIN1+ and AIN1- and the driving circuit common, if available, is connected to
the drive Analog Common (ACOM) terminal.
