■ H3-xx: MFAI Setting Values
Setting Value Function Description Ref.
0 Frequency Reference
The input value from the MFAI terminal set with this function becomes the master frequency reference.
851
1 Frequency Gain
The drive multiplies the analog frequency reference with the input value from the MFAI set with this function.
851
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%.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
851
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%.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
851
4 Output Voltage Bias
Set this parameter to input a bias signal and amplify the output voltage.
852
5 Accel/Decel Time Gain
Enters a signal to adjust the gain used for C1-01 to C1-08 [Acceleration/Deceleration Times 1 to 4] and C1-09
[Fast Stop Time] when the full scale analog signal (10 Vor 20 mA) is 100%.
852
6 DC Injection Braking
Current
Enters a signal to adjust the current level used for DC Injection Braking when the drive rated output current is
100%.
852
7 Torque Detection Level
Enters a signal to adjust the overtorque/undertorque detection level.
Note:
Use this function with L6-01 [Torque Detection Selection 1]. This parameter functions as an alternative to L6-
02 [Torque Detection Level 1].
853
8 Stall Prevent Level
During Run
Enters a signal to adjust the stall prevention level during run if the drive rated current is 100%.
853
9 Output Frequency Lower
Limit
Enters a signal to adjust the output frequency lower limit level as a percentage of the maximum output frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
853
B PID Feedback
Enter the PID feedback value as a percentage of the maximum output frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
