Note:

Example Analog Input Settings
• The function set for terminal A1 is set with Frequency Bias [H3-02 = 0], the gain is 200% [H3-03 = 200.0],
and the bias is 0% [H3-04 = 0.0].
The frequency reference will be at 200% when a signal of 10 V is input.
The frequency reference will be at 100% when a signal of 5 V is input. As the drive output at this time is
restricted by E1-04 [Maximum Output Frequency], the frequency reference will be at 100% when a signal of 5
V or more is input.
Figure 11.99 Freq Reference When the Analog Input Gain Setting Is Adjusted
• The function set for terminal A1 is set with Frequency Bias [H3-02 = 0], the gain is 100% [H3-03 = 100.0],
and the bias is -25% [H3-04 = -25.0].
The frequency reference will be at -25% when a signal of 0 V is input.
When H3-01 = 0 [Terminal A1 Signal Level Select = 0 to 10 V] is set, the frequency reference will be at 0%
when a signal of 0 to 2 V is input. The frequency reference will be at 0 to 100% when a signal of 2 to 10 V is
input.
Signals of both positive and negative polarities are enabled when H3-01 = 1 [-10 to +10 V] is set, and so the
motor rotates in reverse when a signal of 0 to 2 V is input.
