Under-Voltage (Trip Alarm) Detection Time
Program Protection Under-Voltage/Ridethrough
This parameter sets the time that the under-voltage condition must exist to
cause an Under-Voltage Trip.
This parameter is enabled at F627.
Direct Access Number — F628
Parameter Type — Numerical
Factory Default — 0.03
Changeable During Run — No
Minimum — 0.0
Maximum — 10.00
Units — Seconds
Regenerative Power Ridethrough Control Level
Program Protection Under-Voltage/Ridethrough
This parameter is activated during regeneration. It is used to set the low end of
the DC bus voltage threshold that, once the bus voltage drops below this
setting, activates the setting of F302 (Ridethrough Mode).
Activation may be the result of a momentary power loss or an excessive load on
the bus voltage.
During a Ridethrough, regenerative energy is used to maintain the control
circuitry settings for the duration of the Ridethrough; it is not used to drive the
motor.
The motor(s) of the system are stopped and then restarted automatically or may
continue seamlessly if so configured.
See F302 for more information on this parameter.
Note: This parameter setting may increase deceleration times.
Direct Access Number — F629
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 50.00
Maximum — 100.00

Brake Answer Waiting Time
Program Protection Special Protection Parameters
This parameter is used in conjunction with the discrete input terminal setting
Brake Answerback Input (see Table 8 on pg. 217 for more information on this
feature).
After activating the discrete input terminal Braking Request, the setting of this
parameter starts a count-down timer in which 1) a Brake Answerback Input
response must be received or 2) the brake must release before the timer expires.
Should this timer setting expire before the Brake Answerback Input is
returned or the brake releases, a Brake Fault (E-11) is incurred. Otherwise, the
brake releases and normal motor operations resume.
Direct Access Number — F630
Parameter Type — Numerical
Factory Default — 0.0 (Disabled)
Changeable During Run — Yes
Minimum — 0.0 (Disabled)
Maximum — 10.0
Units — Seconds
Brake Release After Run Timer
Program Protection Special Protection Parameters
This parameter sets the time that the brake will hold after the Run command
criteria has been met.
Direct Access Number — F632
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — No
Minimum — 0.00
Maximum — 2.50
Units — Seconds
