Closes when run command is input from the digital operator.
• Overtorque Detection 1 - N.O. (setting: “B”)
Closes during overtorque detection 1 (L6-01, see section L6, Overtorque Detec-
tion).
• Loss of Speed Reference (setting: “C”)
Closes when the speed reference is reduced by 90% within 400ms. The inverter
will respond according to the setting of reference loss selection (L4-05). After refer-
ence loss, if L4-05 = “1,” then operation continues at 80% of the previous speed ref-
erence, and the contact closes.
• Dynamic Braking Resistor Overheat (setting: “D”)
Closes during braking resistor overheating or a braking transistor fault.
• Fault (setting: “E”)
Closes when a fault occurs (except CPF00 and CPF01).
• Alarm (setting: “10”)
Closes while an alarm is displayed.
• Fault Reset (setting: “11”)
Closes while a fault is being reset.
• Timer Output (setting: “12”)
Closes when a timer contact input closes (after On-delay time elapses).
Opens when a timer contact input opens (after Off-delay time elapses).
• Speed Agree 2 (setting: “13”)
Closes whenever the output speed “agrees” with the Speed reference plus or minus
the Speed Agree Detection Width (L4-04). This is used for setting up an alternate
detection width.
