· Loss of Frequency Reference (setting: “C”)
Closes when frequency reference is reduced by 90% within 400ms. The inverter will respond
according to the setting of reference loss selection (L4-05). After reference loss, if L4-05 = “1”, then
operation continues at 80% of the previous frequency reference, 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”)
Closed while fault is being reset.
· Timer Output (setting: “12”)
Closes when timer contact input closes (after On-delay time elapses).
Opens when timer contact input opens (after Off-delay time elapses).
· Frequency Agree 2 (setting: “13”)
Closes whenever the output frequency “agrees” with the frequency reference, plus or minus the
speed agree detection width (L4-04). This is used for setting up an alternate detection width.
