H3: Multi-Function Analog Inputs - YASKAWA U1000 Series Technical Manual

 H3: Multi-Function Analog Inputs
The drive is equipped with three multi-function analog input terminals: A1, A2, and A3. Refer to
of the functions that can be set to these terminals.
H3-01: Terminal A1 Signal Level Selection

Selects the input signal level for analog input A1.
No.
H3-01
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and
bias settings will be simply read as 0%.
Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the
motor will rotate in reverse.
H3-02: Terminal A1 Function Selection

Determines the function assigned to analog input terminal A1.

H3-02
H3-03, H3-04: Terminal A1 Gain and Bias Settings

Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1 (bias).
Both can be used to adjust the characteristics of the analog input signal to terminal A1.
No.

H3-04
Setting Examples
• Gain H3-03 = 200%, bias H3-04 = 0, terminal A1 as frequency reference input (H3-02 = 0):
An input 10 Vdc will be equivalent to a 200% frequency reference and 5 Vdc will be equivalent to a 100% frequency
reference. Since the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will
be equal to E1-04 above 5 Vdc.
