ANALOG I/O
Name Range Description
01 0V 0V reference for analog I/O
02 AIN1
0-10V,
±
10V
Analog Input 1 (default = diff I/P +)
03
AIN2
0-10V,
±
10V
Analog Input 2 (default = diff I/P -)
04 AIN3

09
–10V REF -10V (output) 10V reference for analog i/o. Load 10mA maximum
NOTE
AIN1 and AIN2 are fitted with a link to ensure no noise pick-up when not in use. These terminals can be used together
as a differential
±
10V input (which we call AIN5), but AIN1 and AIN2 must remain within
±
10V relative to 0V. AIN5
has a direct input into the Speed Loop providing a fast speed or torque demand for servos.
All analog inputs/outputs are configurable using the DSE 890 (Drive System Explorer) Configuration Tool supplied on disk.
The table above shows the factory defaults. These analog connections require
±
10V DC which is supplied at terminal X12/08
and X12/09 respectively. For further information refer to the DSE 890 Configuration Tool.
