Brake sequence function
This function outputs operation timing signals of the mechanical brake from the inverter, such as for lift applications.
This function is useful in preventing load slippage at a start due to poor mechanical brake timing and overcurrent alarm in stop
status and enable secure operation.

Description
278
A100
Brake opening frequency 3 Hz 0 to 30 Hz
Set the frequency value calculated by adding approx. 1.0 Hz to the
rated slip frequency. This can be set only when
Pr.278 ≤ Pr.282 .
279
A101
Brake opening current 130% 0% to 400%
Set between 50% and 90% because load slippage is more likely to
occur when a start setting is too low.
The inverter rated current is regarded as 100%, or the rated motor
torque is regarded as 100%. (According to
Pr.639 setting)
