Func
tions
•When the reference frequency reaches 2 Hz or higher than the set value in A052, DC injection
braking is released and the output returns to normal. (Example 6-a)
•If the reference frequency is "0" when the operation starts with analog input, the initial operation is
DC injection braking because both the reference and current frequencies are "0". (Example 6-b)
•If the RUN command is turned on with the frequency reference established (or a value larger than
the A052 setting is input), the initial operation is normal output.
•The operation to return to normal varies depending on the setting of the DC injection braking
method selection (A056).
.Frequency Limit
This function limits the Inverter output frequency.
* To switch to the 2nd control, allocate 08 (SET) to the multi-function input terminal and then turn it on.
