Setting 6: Drive Ready
The output closes when the drive is ready to operate the motor. The terminal will not close under the conditions listed below,
and all Run commands will be disregarded.
• When the power is shut off
• During a fault
• When the internal power supply of the drive has malfunctioned
• When a parameter setting error makes it impossible to run
• Although stopped, an overvoltage or undervoltage situation occurs
• While editing a parameter in the Programming Mode (when b1-08 = 0)
Setting 7: DC Bus Undervoltage
The output closes when the DC bus voltage or control circuit power supply drops below the trip level set in L2-05. A fault in
the DC bus circuit will also cause the terminal set for “DC bus undervoltage” to close.
Status
Description
Open
DC bus voltage is above the level set to L2-05.
Closed
DC bus voltage has fallen below the trip level set to L2-05.
Setting 8: During Baseblock (N.O.)
The output closes to indicate that the drive is in a baseblock state. While in baseblock, output transistors do not switch and no
main circuit voltage is output.
Status
Description
Open
Drive is not in a baseblock state.
Closed
Baseblock is being executed.
Setting 9: Frequency Reference Source
Displays the currently selected frequency reference source.
Status
Description
Open
Frequency reference is provided from External reference 1 (b1-01) or External reference 2 (b1-15).
Closed
Frequency reference is being sourced from the digital operator.
Setting A: Run Command Source
Displays the currently selected Run command source.
Status
Description
Open
Run command is provided from External reference 1 (b1-02) or 2 (b1-16).
Closed
Run command is being sourced from the digital operator.
Settings B, 17, 18, and 19: Torque Detection 1 (N.O., N.C.), Torque Detection 2 (N.O., N.C.)
These digital output functions signal an overtorque or undertorque situation to an external device.
Set up the torque detection levels and select the output function from the table below.
