NOTE: AO1 is a voltage output. To use AO1 as an analog current output, external resistance
needs to be supplied. See the detailed information in P4.53.
If only 1 analog current output is needed, consider using AO2. AO2 is capable of supplying a
true current output (no external resistors needed between the GS4 analog output and the other
device's analog input).
The Parameter memory can only be written to 109 times before a memory error will occur. This
memory error will not occur if using setting #11 or #12.
• Use setting #11 or #12 if the AO value will be changed frequently.
• Use setting #13 if the value will not be changed frequently.
DIP SW1 (above the terminals) sets AO1 to be either 0~10VDC output or -10 to +10VDC output.
•
For 0~10V switch setting: 0=0V; 5000=5V; 10,000=10V�
•
For -10 to +10V setting: 0=-10V; 5000=0V; 10,000=10V�
Setting #11: As 485 AO
•
Write to 26A0 hex (49889 dec) via the RS-485 port to control the output� 0~10,000 ==> 0~100%�
The register will not maintain the value, but the analog signal will remain (if you write a value of
5000 to 26A0h, the analog output will produce 5V but the register will read zero)� Writing via the
Ethernet cards will have no effect�
Setting #12: As COMM Card AO
•
Write to 26A0 hex (49889 dec) via the Ethernet card to control the output� 0~10,000 ==>
0~100%� The register will not maintain the value, but the analog signal will remain (if you write a
value of 5000 to 26A0h, the analog output will produce 5V but the register will read zero)� Writing
via RS-485 will have no effect�
Setting #13: Fixed Value
•
Adjust the value of P4�60 via the keypad to increase or decrease the analog output� Writing to
P4�60 via RS-485 or Ethernet does change the output value�

100�0
Scaling factor for the analog output AO1. This parameter adjusts the analog voltage level of the
output.
NOTE: For 100% of gain via communications, write a value of 1000.
