Omron MX2 - Add Frequency

98
"A" Group: Standard Functions Section 3-5
Add Frequency - The inverter can add or subtract on offset value to the out-
put frequency setting which is specified by A001 (will work with any of the five
possible sources). The ADD Frequency is a value you can store in parameter
A145. the ADD Frequency is summed with or subtracted from the output fre-
quency setting only when the [ADD] terminal is ON. Function A146 selects
whether to add or subtract. By configuring an intelligent input as the [ADD] ter-
minal, your application can selectively apply the fixed value in A145 to offset
(positively or negatively) the inverter output frequency in real time.
Input Range Settings - The parameters in the following table adjust the input
characteristics of the VR (POT meter on external operator) input. When using
A142 B input select for calculate

Seven options:
00... Operator
01... VR
02... Terminal [O] input
03... Terminal [OI] input
04... RS485
05... Option
07... Pulse train input

A143 Calculation symbol Calculates a value based on the A
input source (A141 selects) and B
input source (A142 selects). Three
options:
00... ADD (A input + B input)
01... SUB (A input - B input)
02... MUL (A input * B input)
