Table 5-32: No Load Brake Parameter Settings
Parameter Display Function Range Default
C08-01 Torque Comp Time Amount of time for the Torque Comp value to reach
300%.
0.00–2.55 sec 1.00
C08-02 IFB OK Time Sets the amount of time to look for the current
feedback to be OK before posting a BE2 alarm.
Setting this parameter to 0.00 will disable torque
proving at start & eliminate BE2 detection (consult
factory before disabling torque proving).
0.00–2.55 sec 1.00
C08-03 Min Brk Rel Trq Minimum brake release torque. 0–300% 10
C08-04 Rollback Timer Sets the amount of time for the brake to release and
for brake feedback to be received into the Brake
Answer Back Multi-Function Digital Input at start
before posting BE1 or BE4 alarm. It is also the time
period during which the amount of rollback is
checked.
0.00–2.55 sec 0.30
C08-05 Rollback Count Detection counts for excessive rollback.
4 pulses = 1 ppr of F01-01
0–15000 pulses 800
C08-06 BE3/Alt Torq Tim Time period which C08-07 is measured. Also see
C08-08.
0.00–2.55 sec 0.30
C08-07 BE3 Detect Count Detection count for Encoder/Seized-Brake Alarm
(BE3). It is the minimum encoder pulse count, during
the time period of C08-06, below which the BE3
alarm is triggered.
4 pulses = 1 ppr of F01-01
0–15000 pulses 10
C08-08 Alt Rev Trq Lim For a LOWER command in the NLB Hoist Motion
Mode only-Torque limit for time of C08-06 to prevent
driving through a brake that has failed closed with a
load on the hook.
0–300% 25
C08-09 Zero Speed Level Determines speed feedback at which Load Float
activates.
0.0–10.0 Hz 1.0
C08-10 Load Float Time After stop command time period during which the
load is held at the zero-position and the electric
brake is not set.
0-65535 sec 10*
C08-11 Brake Set Delay Sets the amount of time for the brake to set and for
brake feedback to be removed from the Brake
Answer Back Multi-Function input at stop before
posting a BE5 Alarm.
0.0–25.5 sec 0.7
C08-12 BE6 Detect Time Time period during which the electric brake is set
and tested for sustaining the load.
NOTE: To disable BE6 detection, set C08-12 to 0.0.
0.0–25.5 sec 5.0
C08-13 BE6 Max Count Total pulse counts must be less than C08-13, during
C08-12, otherwise BE6 alarm.
4 pulses = 1 ppr of F01-01
0–15000 pulses 250
C08-14 Brake Hold Speed The frequency the VFD outputs to push against the
brake for brake proving at start as well as the
frequency the VFD continues to output until Brake
Set Delay Timer expires or the Brake Answerback
MFDI is removed.
0.0–25.5% 0.0
C08-15 Load Float Ext T Load Float extension time enabled by MFDI=5D. 0–65535 sec 10
