7 Other Functions
(a) Edge operation (A056 = 00)
Example 4-a. During startup
Example 5-a. During stop (with A053 setting)
Example 6-a. During stop (A053 = 0.0)
Note During free running and during DB operation, the output frequency is 0.
Controlling DC Injection Braking Only via Set Frequency (A051 = 02)
Use this method to control DC injection braking only by changing the set frequency.
Set the DC Injection Braking Selection (A051) to 02 (Operates only via set frequency).
• When A051 is set to 02, the external DC injection braking terminal function is disabled.
• If both the set frequency and the output frequency are equal to or lower than the A052 value with the
RUN command ON, the inverter starts DC injection braking. (Example 1-a)
• When the set frequency becomes +2 Hz higher than the A052 value, the inverter releases DC injec-
tion braking and returns to normal output. (Example 1-a)
• The inverter releases DC injection braking if the RUN command turns OFF with DC injection enabled.
(Example 1-b)
• If the set frequency starts from 0 via analog input etc., the inverter resets both the set frequency and
the output frequency and starts operation with DC injection braking. (Example 1-b)
• If the RUN command turns ON via analog input etc. with the set frequency larger than the A052
value, the inverter starts operation with the normal frequency. (Example 1-a)
7 - 98
(b) Level operation (A056 = 01)
Example 4-b. During startup
Example 5-b. During stop (with A053 setting)
Example 6-b. During stop (A053 = 0.0)
