278 Brake opening frequency 0.01 Hz 3 Hz 0–30 Hz
Set to the rated slip frequency of the motor
+ about 1.0 Hz.
This parameter may be set only if Pr. 278
Pr. 282.
✔ ✔ ✔

279 Brake opening current 0.1% 130% 0–200%
Generally, set this parameter to about 50 to
90%. If the setting is too low, the load is
liable to drop due to gravity at start.
Suppose that the rated inverter current is
100%.

281 Brake operation time at start 0.1 s 0.3 s 0–5 s
Pr. 292 = 7: Set the mechanical delay time
until the brake is loosened.
Pr. 292 = 8: Set the mechanical delay time
until the brake is lo about 0.1 to
0.2 s.
✔ ✔ ✔
282 Brake operation frequency 0.01 Hz 6 Hz 0–30 Hz
At this frequency, the brake opening request
signal (BOF) is switched off. Generally, set
this parameter to the Pr. 278 s 3 to
4 Hz.This parameter may be set only if Pr.
278
Pr. 282.
✔ ✔ ✔
283 Brake operation time at stop 0.1 s 0.3 s 0–5 s
Pr. 292 = 7: Set the mechanical delay time
until the brake is 0.1 s.
Pr. 292 = 8: Set the mechanical delay time
until the brake is about 0.2 to 0.3
seconds.
