5.7 H: Terminal Functions
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference 299
Example: When you set frequency gain for terminal A2
• H3-10 = 1 [Terminal A2 Function Selection = Frequency Gain]
• A 50% frequency gain is input to terminal A2
• A frequency reference of 80% is input from terminal A1
The calculated frequency reference is 40% of the maximum output frequency.
■ 2: Auxiliary Frequency Reference 1
Setting Value Function Description
2 Auxiliary Frequency
Reference 1
Sets Reference 2 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 1) from the
analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of 100%.
■ 3: Auxiliary Frequency Reference 2
Setting Value Function Description
3 Auxiliary Frequency
Reference 2
Sets Reference 3 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 2) from the
analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of 100%.
■ 4: Output Voltage Bias
Setting Value Function Description
4 Output Voltage Bias Set this parameter to input a bias signal and amplify the output voltage.
The gain (%) for the MFAI terminals A1 and A2 is 100% of the voltage class standard, which is 208 V for 208/240 V
and 480 V for 480 V. The bias (%) for MFAI terminals A1 and A2 is 100% of the voltage configured for E1-05
[Maximum Output Voltage].
Note:
Parameters H3-03 [Terminal A1 Gain Setting] and H3-11 [Terminal A2 Gain Setting] independently set the gain for each terminal A1 and
A2. Parameters H3-04 [Terminal A1 Bias Setting] and H3-12 [Terminal A2 Bias Setting] independently set the bias for each terminal A1 and
A2.

■ 5: Accel/Decel Time Gain
Setting Value Function Description
5 Accel/Decel Time Gain Enters a signal to adjust the gain used for C1-01 to C1-04 [Acceleration/Deceleration Times 1 and 2] and C1-09 [Fast Stop Time]
when the full scale analog signal (10 V or 20 mA) is 100%.
When you enable C1-01 [Acceleration Time 1], the acceleration time is:
Acceleration Time 1 = Setting value of C1-01 × acceleration and deceleration time gain / 100
