Detection 2
Refer to L4-01: Speed Agreement Detection Level on page 106
Setting 6: Drive Ready
Output closes whenever the drive is ready to operate the motor.
Status
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 75
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 depends on the setting of parameter E1-01. Refer to E1-01 for details. A fault in the DC bus charge circuit will
also cause the DC Bus Undervoltage output to close.
Status
Open DC bus voltage is above the undervoltage level.
Closed DC bus voltage has fallen below the undervoltage level.
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
Open Drive is not in a baseblock state.
Closed Baseblock is being executed.
Settings B and 17: Torque Detection (N.O./N.C.)
These digital output functions can be used to signal an overtorque situation to an external device.
Set up the torque detection and select the output function from the table below.
108 for details.
Setting Status
B Closed
17 Open
Setting E: Fault
The Fault configured digital output will close whenever the drive experiences a fault (this excludes faults CPF00 and
CPF01).
Setting F: Not Used
Use this setting when the terminal is not used or when using the terminal as a throughput.
When set to "F", the output is not set by any drive function but it can be switched by a PLC via MEMOBUS/Modbus
communications interface (through mode).
Setting 10: Minor Fault
Output closes when a minor fault condition is present.
