Digital Output

There are 10 programmable digital outputs (DO1-10). DO1-4 are photo-coupler outputs and must
be used with 24Vdc. DO1-3 may be connected to an external 24V supply if desired. DO4 is connected the
drive internal 24V supply. The other 6 outputs (DO5-10) are form C relay outputs. These relays can be
programmed to any bit in any word in the drive. The most commonly used bits can be found in the
SSEQ_OUT1-4 words. The word assignment is made via DO1_AS – DO10_AS parameters.

Analog Input

The drive has three general-purpose analog inputs (AIN1-3). They can be configured to any variable in the
drive through assignment of AINn_AS (where n = 1 to 3 ).
As a general-purpose analog input, the standard I/O circuit brd. (XIO) has one general-purpose analog input
(AIN1). Expanded I/O brd. (EXIO) has two additional inputs (AIN2 and AIN3). AIN1 has an option for
current input thru an internal resistor, but AIN2 and 3 are voltage input only.
Each analog input signal is converted to the digital value through a 12-bit A/D converter. A ±10 Vdc input is
converted to counts by software and is stored in the target data register. Since this signal is directly
connected to the control circuit, it is recommended that an isolation transducer be used. The data register,
the gain and the offset are set with the following parameters:
AIN#_AS
AIN#_GS
AIN#_OS
The "#" of each parameter name denotes the AD channel number. The following figure shows the input circuit:
