1 7 erminal Functions
Settin 7 DC Bus Under olta e
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
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.
Settin 8 Durin Basebloc (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
Open Drive is not in a baseblock state.
Closed Baseblock is being executed.
Settin Fre uency e erence Source
Displays the currently selected frequency reference source.
Status
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 HOA keypad.
Settin A un Command Source
Displays the currently selected Run command source.
Status
Open Run command is provided from External reference 1 (b1-02) or 2 (b1-16).
Closed Run command is being sourced from the HOA keypad.
Settin B and 17 or ue Detection 1 (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.

Settin Status
B Closed
17 Open
Settin C Fre uency e erence Loss
An output set for this function closes when frequency reference loss is detected.
Detection Selection on page 113
Settin E Fault
The output closes when the drive faults (excluding CPF00 and CPF01 faults).
Settin F rou Mode
Select this setting when using the terminal in a pass-through mode. When set to F, an output does not trigger any function in
the drive. Setting F, however, still allows the output status to be read by a PLC via a communication option or MEMOBUS/
Modbus communications.
Settin 1 Minor Fault
The output closes when a minor fault condition is present.

Torque detection 1 (N.O.):
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in
parameter L6-02 for longer than the time specified in parameter L6-03.
Torque detection 1 (N.C.):
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in
parameter L6-02 for longer than the time specified in parameter L6-03.
