Setting 6: DC Injection Braking Current
The current level used for DC Injection Braking is set as a percentage of the drive rated current.
Setting 7: Torque Detection Level
Using this setting, the overtorque/undertorque detection level for torque detection 1 (L6-01) can be set by an analog input.
The analog input replaces the level set to L6-02. An analog input of 100% (10 V or 20 mA) sets a torque detection level equal
to 100% drive rated current/motor rated torque. Adjust the analog input gain if higher detection level settings are required.
Refer to L6: Torque Detection on page 255
Setting 8: Stall Prevention Level
Allows an analog input signal to adjust the Stall Prevention level.
use the lower value of the Stall Prevention level set to L3-06 or the level coming from the selected analog input terminal.
Setting 9: Output Frequency Lower Limit Level
The user can adjust the lower limit of the output frequency using an analog input signal.
Setting B: PID Feedback
Supplies the PID feedback value. This setting requires PID operation to be enabled in b5-01.
Methods on page 161.
Setting C: PID Setpoint
Supplies the PID setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PID setpoint.
PID operation to be enabled in b5-01 to use this setting.
Setting D: Frequency Bias
The input value of an analog input set to this function will be added to the frequency reference. This function can be used with
any frequency reference source.
