P4.54 Analog Output 2 (AO2)
♦R/W 0436 41079

11: RS485 AO
12: Comm Card AO
13: Fixed Value
0
DIP SW2 (above the terminals) sets AO2 to be either a voltage output (0~10VDC) or a true current
output (0~20mA or 4~20mA per P4.57).
The Parameter memory can only be written to 10
9
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�
Setting #11: As 485 AO
•
Write to 26A1 hex (49890dec) 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 26A1 hex (49890dec) 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�61 via the keypad to increase or decrease the analog output� Writing to
P4�61 via RS-485 or Ethernet does change the output value�

P4.55 AO2 Gain
♦R/W 0437 41080
Range/Units (Format: 16-bit unsigned) Default
0�0~500�0%
100�0
Scaling factor for the analog output AO2. This parameter adjusts the analog voltage level of the
output.
NOTE: For 100% of gain via communications, write a value of 1000.
Type Hex Addr Dec Addr
P4.56 AO2 Negative Value Handle
♦R/W 0438 41081
Range/Units (Format: 16-bit binary) Default
0: Absolute Value
1: 0V When Negative
2: Offset 5V = 0 Value
0
This parameter setting can be used for determining AO2 output direction, the same as described
in P4.52 (page 4–107).
