BRAKING CONTROL FUNCTION
This is a function that the inverter controls external braking
used in systems like elevators. By braking control function
selection(b120) is set to valid(01), this function is performed
as the following below.
(1) When running command turns on, the inverter begins to
operate and accelerate to releasing frequency.
(2) After output frequency arrives releasing freaqyency, the
inverter outputs breaking releasing signal (BRK) after
waiting for the time for confirmation of releasing braking
which is set in (b121).
However, if output current of the inverter is within releasing
current which is set in (b121), braking releasing signal
would not output, the inverter would occur the trip and output braking error signal (BER).
(3) When braking confirmation signal (BOK) is set to intelligent input terminal (when 44 is set to C001 – C008),
if braking releasing signal is outputted, the inverter would not accelerate during just waitng time for braking confirmation which is set in
(b124).
If braking confirmation signal is not inputted within waiting time for braking confirmation, the inverter would output braking error signal
(BER) and would occur the trip
If braking confirmation signal is not set to intelligent input braking terminal, the waiting time for braking confirmation would be invalid,
and after the inverter would output braking releasing signal, proceed to (4).
(4) After braking confirmation signal is inputted( after braking releasing signal is outputted when BOK is not selected), the inverter waits for
the time for acceleration, and then begins to accelerates again and accerates to the frequency.
(5) When running command turns off, the inverter decelerates to releasing frequency and turns braking releasing signal(BRK) off.
(6) When braking confirmation signal (BOK) is set to intelligent input terminal(when 44 is set to C001 – C008),
after braking releasing signal turns off, the inverter would not decelerate during just the waitng time for braking confirmation which is
set in (b124), and would wait for braking confirmation singal turnning off.
If braking confirmation signal does not turn off within the waiting time for braking confirmation, rhe inverter would output braking error
signal (BER) and would occur the trip
If braking confirmation signal is not set to intelligent input braking terminal, the waiting time for braking confirmation would be invalid
and after the inverter would output braking releasing signal, proceed to (7).
(7) After braking confirmation signal turns off ( after braking releasing signal turns off), the inverter waits for the waiting time for stop, and
then begins to decelerate again and decelerates to 0 Hz
