Chapter 7 Detailed Explanations of Functional Parameters
Explanation
0: Positive direction
1: Negative direction
P314
Analogue reverse options Initial value: 0
Setting range
0-1
Unit
1
Explanation
0: No reverse at negative bias voltage
1: Reverse allowed at negative bias voltage
The parameter group of P310-P314 decides the running condition
of analogue, including output frequency and direction. According to
actual need of user, they can form various control curves.
P310 Frequency of low analog
Frequency of lower analogue decides the output frequency of
lowest analogue input, corresponding to analogue minimum voltage
(current) input.
P311 Direction of low analog
Direction of lower analogue decides the running condition at low
frequency, whether it is Forward or reverse.
P312 Frequency of high analog
Analogue high-end frequency determines high-end output
frequency, and is corresponding to analogue maximum voltage
(current) input.
P313 Direction of high analog
Analogue high-end direction determines whether the running status
of high-end frequency is forward or reverse.
P314 Analog input reverse selection
Analogue reverse selection determines running status of analog
negative bias voltage, satisfied curve needed by customer can be
constituted by using above parameter.
Example 1: upper computer output 2-10 V signal to control inverter,
50Hz reverse to 50Hz forward running.
