5.9.3 Analog
input
compensation
Addition compensation or fixed ratio analog compensation (override) with terminal 2 set to auxiliary
input is applicable to the multi-speed operation or terminal 2/terminal 4 speed setting signal (main
speed).
Addition compensation (Pr. 242, Pr. 243)
●
A compensation signal is addable to the main speed setting for such as synchronous or continu-
ous speed control operation.
●
Setting a value of "0 to 3, 6, 7, 10 to 13, 16, and 17" to Pr. 73 adds the voltage between terminals
1 and 5 to the voltage signal of the terminals 2 and 5.
●
When Pr. 73= "0 to 3, 6, or 7", and if the result of addition is negative, it is regarded as 0 and the
operation is stopped. When Pr. 73 = "10 to 13, 16, or 17", the operation is reversed (polarity
reversible operation) with STF signal ON.
●
The terminal 1 compensation input is addable to the multi-speed setting or terminal 4 (initial
value: 4 to 20 mA).
●
The degree of addition compensation to terminal 2 is adjustable with Pr. 242.
The degree of addition compensation to terminal 4 is adjustable with Pr. 243.
●
Analog command value with use of terminal 2
= terminal 2 input + terminal 1 input × (Pr. 242/100 [%])
Analog command value with use of terminal 4
= terminal 4 input + terminal 1 input × (Pr. 243/100 [%])
