15. (A) Application Parameters
15.1 Brake sequence function
NOTE
• During deceleration, inverter output is shut OFF when the frequency reaches
Pr.13 Starting frequency
or 0.5 Hz, whichever
is lower. For
Pr.278 Brake opening frequency
, set a frequency equal to or higher than the
Pr.13
setting or 0.5 Hz.
•
Pr.285 Overspeed detection frequency
is valid under encoder feedback control (used with the Vector control compatible
option) even if a value other than "7 or 8" is set in
Pr.292 Automatic acceleration/deceleration
.
• Setting
Pr.278
too high activates the stall prevention and may cause E.MB4.
• E.MB4 occurs when the time period calculated by adding
Pr.280
to the acceleration time from
Pr.13
to
Pr.278
reaches or
exceeds 2 seconds.
