5.7 H: Terminal Functions
Setting A: Run command source
A digital output programmed for this function shows the Run command source that is currently selected.
Status
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.
Setting B, 17, 18, 19: Torque detection 1 (N.O., N.C.), Torque detection 2 (N.O., N.C.)
These digital output functions can be used to 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.
page 291 for details.
Setting Status
B Closed
17 Open
18 Closed
19 Open
Setting C: Frequency reference loss
An output set for this function will be closed if frequency reference loss is detected.
Reference Loss Detection Selection on page 289
Setting D: Braking resistor fault
An output programmed for this function will close when the dynamic braking resistor (DB) overheats or the braking
transistor is in a fault condition.
Setting E: Fault
The digital output will close whenever the drive experiences a fault (this excludes faults CPF00 and CPF01).
Setting F: Through 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.
Setting 10: Minor fault
Output closes when a minor fault condition is present.
Setting 11: Fault reset command active
Output closes whenever there is an attempt to reset a fault situation from the control circuit terminals, via serial
communications, or using a communications option card.
Setting 12: Timer output
This setting configures a digital output terminal as output for the timer function.

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.
Torque detection 2 (N.O.):
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in parameter L6-05 for longer than
the time specified in parameter L6-06.
Torque detection 2 (N.C.):
Output current/torque exceeds (overtorque detection) or is below (undertorque detection) the torque value set in parameter L6-05 for longer than
the time specified in parameter L6-06.
