Refer to L4-01/02: Speed Agreement Detection Level and Detection Width on page 227
for details on setting the detection
width.
Setting 6: Drive Ready
Output closes whenever the drive is ready to operate the motor.
Status
Description
Open
During power up, initialization, fault or in Programming Mode (while b1-08 = 0 or 2).
Closed
Drive is ready for operation.
Refer to b1-08: Run Command Selection while in Programming Mode on page 127
for details on the setting of b1-08.
Setting 7: DC Bus Undervoltage
Output closes whenever the DC bus voltage or control circuit power supply drops below the trip level. The undervoltage trip
level is determined by L2-05. A fault in the DC bus charge circuit will also cause the DC Bus Undervoltage output 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.)
Output closes to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors are not switched
and no voltage will be output.
Status
Description
Open
Drive is not in a baseblock state.
Closed
Baseblock is being executed.
Setting 9: Frequency Reference Source
A digital output programmed for this function shows the frequency reference source that is currently selected.
Status
Description
Open
Frequency reference is provided from External Reference 1 (b1-01) or 2 (b1-15)
Closed
Frequency reference is being sourced from the digital operator.
Setting A: Run Command Source
A digital output programmed for this function shows the Run command source that is currently selected.
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.
Setting B/17/18/19: Torque Detection 1 (N.O./N.C.) and 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 and select the output function from the table below.
Refer to L6: Torque Detection on page
for details.
