YASKAWA VARISPEED-616G5, Instruction Manual

Basic Operation
6.1.2 Frequency Reference Settings: b1-01, H3-01, H3-08, H3-09
6 - 6
J
Function and Signal Level for Multi-function Analog Input (Terminal 16):
H3-04, H3-05
D
This function is useful when switching between two analog inputs. The input is from terminal 16.
D
When using the multi-function input (terminal 16) as the frequency reference terminal, first set the
multi-function analog input function to “Auxiliary Reference” by setting constant H3-05 to 0.

The auxiliary reference is factory-preset to 0.
D
After setting H3-05 to 0, set any one of the multi-function inputs (H1-01 through H1-06) to a value
of 3 (multi-step speed reference 1).
D
When a multi-function analog input has been set to “Auxiliary Reference,” it is treated as frequency
reference 2 during multi-step speed operation, so it can’t be used unless the multi-step speed reference
1 has been set.

J
Adjusting Analog Inputs: H3-02, H3-03, H3-06, H3-07, H3-10, H3-11, H3-12
D
There are three constants used to adjust the analog inputs: The gain, bias (both set separately for each
input), and filter time constant (a single value for all of the inputs).
•
The gain and bias can be adjusted separately for each analog input (terminals 13, 14, and 16).
Gain: Set the frequency corresponding to a 10 V (20 mA) input as a percentage of the
maximum frequency. (The maximum output frequency set in E1-04 is 100%.)
Bias: Set the frequency corresponding to a 0 V (4 mA) input as a percentage of the
maximum frequency. (The maximum output frequency set in E1-04 is 100%.)
•
Set the gains and biases for terminals 13, 14, and 16 as follows:

* The settings for terminal 16 are valid only when the multi-function analog input has been se-

the values set for terminal 13 will be used.
