Under-Voltage (trip alarm) Detection Time
Program
Protection
Undervoltage/Ridethrough
This parameter sets the time that the under-voltage condition must exist
to cause an Under-Voltage trip when this function is enabled at
.
Direct Access Number —

Parameter Type —
Numerical
Factory Default —
0.03
Changeable During Run —
No
Minimum — 0.00
Maximum — 10.00
Units — Seconds
Regenerative Power Ridethrough Control Level
Program
Protection
Undervoltage/Ridethrough
This parameter sets the low end of the DC bus voltage threshold that,
once it drops below this setting, will activate the setting of
(Ridethrough Mode). Activation may be the result of a momentary power
loss or an excessive load on the bus voltage. Once activated, the system
will attempt to maintain the bus voltage level set here until the motor
stops.
Note:
This feature may decrease deceleration times.

(ASD-Dependent)
Changeable During Run —
Yes
Minimum — 50.00
Maximum — 100.0

Brake Answer Waiting Time
Program
Protection
Brake Fault Timer
This parameter is used in conjunction with the discrete input terminal
setting 64 [System Consistent Sequence (BA: braking answer)] (see item
64 of
for additional information on this feature).
After activating the discrete input terminal System Consistent Sequence
(B: braking release), the setting of this parameter defines a window of
time in which 1) a Braking Answer response must be received or 2) the
brake must release.
Should this timer setting expire before the Braking Answer is returned or
the brake releases, a Brake Fault is incurred. Otherwise, the brake
releases and normal motor operations resume.

Brake Release After Run Timer
Program
Protection
Brake Fault Timer
This parameter sets the time that the brake will hold after the Run
command criteria has been met.

Program
Special
Earth Fault
This parameter sets the threshold level (%) that must be exceeded to
meet the Earth Fault Alarm activation criteria.
Direct Access Number —
