· Frequency Detection 2 (setting: “5”)
Closes whenever the output frequency is at or above the speed agree detection level (L4-01). During
deceleration from above the detection level, the output frequency decreases through the detection
bandwidth (L4-02) before the contact opens again. This is effective during both forward and reverse
operation.
· Inverter Ready (setting: “6”)
Closes when the inverter is ready for operation (no faults or alarms).
· DC Bus Undervoltage (setting: “7”)
Closes when the main circuit DC bus voltage or control circuit power supply is drops below the trip
level, or when the main circuit magnetic contactor (MC) turns OFF.
· Baseblock 1 - N.O. (setting: “8”)
Closes when the inverter output shuts OFF.
· Frequency Reference Selection (setting: “9”)
Opens when the frequency reference is input from the control circuit terminals or an option.
Closes when the frequency reference is input from the digital operator.
· Run Command Selection (setting: “A”)
Opens when run command is input from the control circuit terminals or an option.
Closes when run command is input from the digital operator.
· Overtorque Detection 1 - N.O. (setting: “B”)
Closes during overtorque detection 1 (see section L6, Overtorque Detection, on page 113).
