During RUN 1 Closed: A Run command is active or voltage is output.
Open: Output frequency is above the minimum output frequency set in E1-09.
Zero Speed
Closed: Output frequency is below the minimum output frequency set in E1-09.
Closed: Output frequency equals the speed reference (plus or minus the hysteresis
Fref/Fout Agree1
set to L4-02).
Closed: Output frequency and speed reference equal L4-01 (plus or minus the
Fref/Set Agree 1
hysteresis set to L4-02).
Closed: Output frequency is less than or equal to the value in L4-01 with hysteresis
Freq Detect 1
determined by L4-02.
Closed: Output frequency is greater than or equal to the value in L4-01 with
Freq Detect 2
hysteresis determined by L4-02.
Drive Ready Closed: Power up is complete and the drive is ready to accept a Run command.
Power Supply Err Closed: DC bus voltage is below the Uv trip level set in L2-05.
Closed: Drive has entered the baseblock state (no output voltage).
Closed: An overtorque or undertorque situation has been detected.
Trq Det 1 N.O.
Closed: Analog frequency reference has been lost.
Fault Closed: Fault occurred.
Set this value when using the terminal in the pass-through mode.
Not Used
Closed: An alarm has been triggered, or the IGBTs have reached 90% of their
Minor Fault
expected life span.
Closed: A command has been entered to clear a fault via the input terminals or
Reset Cmd Active
from the serial network.
Fref/Fout Agree2 Closed: When drive output frequency equals the frequency reference ±L4-04.
Fref/Set Agree 2 Closed: When the drive output frequency is equal to the value in L4-03 ±L4-04.
Closed: When the drive output frequency is less than or equal to the value in L4-03
Freq Detect 3
±L4-04.
Closed: When the output frequency is greater than or equal to the value in L4-03
Freq Detect 4
±L4-04.
Open: Overtorque or undertorque has been detected.
Trq Det 1 N.C.
Reverse Dir Closed: Drive is running in the reverse direction.
Open: Drive has entered the baseblock state (no output voltage).
Dur Flt Restart Closed: An automatic restart is performed
Closed: Heatsink temperature exceeds the parameter L8-02 value, or an external
OH Prealarm
device has triggered an oH2 alarm via multi-function input H1-oo = B.
Closed: Cooling fan, electrolytic capacitors, IGBTs, or the soft charge bypass relay
