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]
Set this parameter to input a bias signal to amplify the output voltage.
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 V or 20 mA) is 100%.
Enters a signal to adjust the current level used for DC Injection Braking when the drive rated output current is 100%.
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].
Enters a signal to adjust the stall prevention level during run if the drive rated current is 100%.
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]
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]
Enters the PID setpoint 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]
Enters the bias value added to the frequency reference 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]
Uses the motor Positive Temperature Coefficient (PTC) thermistor to prevent heat damage to the motor as a percentage of the
current value when the 10 V analog signal is input.
Use this setting for unused terminals or to use terminals in through mode.
Enters the forward torque limit if the motor rated torque is 100%.
Enters the load torque limit if the motor rated torque is 100%.
Enters the regenerative torque limit if the motor rated torque is 100%.
Enters the torque reference if the motor rated torque is 100%. This setting is the torque limit for speed control.
Enters the torque compensation value if the motor rated torque is 100%.
Enters the torque limit that is the same for all quadrants for forward, reverse, and regenerative operation if the motor rated torque is
100%.
Enters the PID differential feedback value if the full scale analog signal (10 V or 20 mA) is 100%.
Use this setting for unused terminals or to use terminals in through mode.
