The brake control function allows you to make the inverter control an external
brake used for a lift or other machines. To enable this function, specify ""
(enabling the brake control function) for the Brake Control Enable (). This
function operates as described below.
1. When the inverter receives an operation command, it starts the output and
accelerates the motor up to the Brake Release Frequency Setting ().
2. After the Brake Release Frequency Setting is reached, the inverter waits
for the braking wait time (), and then outputs the brake release signal
(BOK). However, if the inverter output current has not reached the brake
release current (), the inverter does not output the brake release sig-
nal, but trips and outputs a brake error signal (BER).
3. When the braking confirmation signal (BOK) has been assigned to an in-
telligent input terminal (that is, when "" is specified for one of "" to
""), the inverter waits for the Brake Wait Time for Confirmation ()
without accelerating the motor after receiving the brake release signal. If
the inverter does not receive the braking confirmation signal within the
braking confirmation time (), it trips with the braking error signal (BER)
Description
Selects how the inverter resumes
operation when free-run stop
(FRS) is cancelled, three options:

0 Hz start

f-match (Frequency
matching start)

Actv. f-match (Active
Frequency Matching restart)
Select how the inverter stops the
motor, two option codes:

DEC (decelerate to stop)

FRS (free-run to stop)
