H2 Digital Outputs

· 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.
