PID1 feedback data selection
A
• This selects PID1 feedback data.
• In the case of setting feedback data with one input,
set 00: None to [AH-52]/[AH-53] and 01: Add to
[AH-54] to disable the input destination 2/3.
Analog input Ai1 to Ai6 (01 to 06)
RS 485 communication (08)
Option 1 to 3 (09 to 11)
Pulse train input (main unit) (12)
Pulse train input (option) (13)
Operation of operator [AH-54]
A
• When 01 to 07 is selected in operator [AH-54],
calculation will be targeted to feedback data 1 and
feedback data 2.
• When 08 to 10 is selected in operator [AH-54],
calculation will be targeted to feedback data 1 to 3.
• Calculation result of operator [AH-54] will be
restricted in a range of -100.00 to 100.00 (%).
