C08-19
Brk Slip Reset
Determines if BE6 alarm is automatically reset. If enabled,
VFD will always perform BE6 test after Load Float to
determine if brake is operational and the fault can be cleared.
If disabled the VFD will remain in BE6 alarm state until power
is cycled.

Brake Test Torq
Motor runs in Forward direction at C08-25 speed when MFDI =
61 is active. Brake output relay is not energized, PGO and
DEV detection are disabled. Monitor Brake Test Torque at
U01-86.

C08-28
Trq Check Time
Time during which the torque must be above C08-03 or C08-
16 before releasing the brake. Increasing this time allows the
load to stabilize and minimize erroneous BE2 faults. Disabled
if set to 0.00.

Min REV Time
Maximum amount of time, after the brake has been released,
the VFD will remain running at in the down direction.

C08-30
Pos Trq Time
Time that the internal torque signal must be positive before the
VFD will be allowed to transition from reverse to forward. Only
in effect within the C08-29 time, after brake release.
0.0–25.5 sec
