5.6 H: Terminal Functions Output L4-01 Frequency Detection 2 Figure 5.24 Frequency Detection 2 Time Chart Refer to L4-01: Speed Agreement Detection Level on page 106 for details on setting the detection width. Setting 6: Drive Ready Output closes whenever the drive is ready to operate the motor. Refer to b1-08: Run Command Selection while in Programming Mode on page 75 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 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. 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. 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. Refer to L6: Torque Detection on page 108 for details. Parameter Details 5 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. SIEP C710606 33A OYMC AC Drive – J1000 User Manual 97 quency 2 Hz L4-01 OFF 2 Hz ON Status Description Open During power up, initialization, fault or in Programming Mode (while b1-08 = 0 or 2).
Closed Drive is ready for operation. Status Description Open DC bus voltage is above the undervoltage level. Closed DC bus voltage has fallen below the undervoltage level. Status Description Open Drive is not in a baseblock state. Closed Baseblock is being executed. Setting Status Description B Closed Torque Detection (N.O.): Output current/torque exceeds the torque value set in parameter L6-02 for longer than the time specified in parameter L6-03. 17 Open Torque Detection (N.C.): Output current/torque exceeds the torque value set in parameter L6-02 for longer than the time specified in parameter L6-03.
