P3.51 Brake Delay Time
Range/Units (Format: 16-bit unsigned)
0�000~65�000 sec
When P3.51 is used with MFO selection #42, see the MFO definition #42 (P3.17) for more details.
When P3.51 is used with MFO selection #12 AND the GS4 drive runs after P3.51 delay time, the
corresponding Multi-Function Output terminal (12: brake release function) will be ON when used
with DC Injection Braking (P1.25, P1.26, P1.27).
Timing chart for parameter P3.51 used with DC Injection (DCI) braking:
If Brake Delay Time is longer than DCI Start Time, the Brake output will energize at the
Start of the Accel ramp (total delay time is never more than DCI Start Time).
If Brake Delay Time is longer than DCI Stop Time, the brake output will energize at the
end of DCI Stop Time (the total delay time is never more than DCI Stop Time).
