vacon 500x parameters
7
Configures the frequency under which direct current will be applied to the drive when DC Inject Config is
set to “DC on Freq.” If this parameter is set to 0.0, the parameter operates in the same way as “DC at Stop.”
410 DB Config
Default: DB Internal
Range: n/a
Level 2
Determines whether an external or internal dynamic brake is utilized or disabled. The drive provides an
internal dynamic brake (DB) to assist in stopping. If desired, an external resistor can be connected to DB
and B+ for additional capacity.
The following data values may be assigned to this parameter:
Parameter Value
Description
DB Internal
Internal dynamic braking active
DB External
External dynamic braking active
NOTE: There is
no drive protection for an overheating external DB resistor!
No Dyn Brk
Dynamic braking circuit disabled
Int-ARCTIC
When DB Config is configured to “Int-ARCTIC,” dynamic braking becomes active if
the internal control board temperature drops below -7 degrees C. When the DB
becomes active, an “ARCTIC Mode” warning flashes on the keypad. If the board
temperature drops below -10 degrees C, the drive will be disabled and not allowed to
run. The keypad will indicate a “Not enabled” state at this point. If the board
temperature heats up after being below -10 degrees C, the drive must meet these
criteria before operating again:
a) Board temperature must be above -9 degrees C, and
b) Board temperature must stay above -9 degrees C until a time period has elapsed.
The time period is dependent on how far below -10 degrees C the board was. Each
degree below -10 degrees C adds another 4 minutes before restart.
414 S Ramp Rounding
Default: 25%
Range: 1-100%
Level 2
This parameter is used to define the amount of rounding or S-curve to the Accel and Decel ramp. The
amount of rounding is split evenly between the beginning and the end of the ramp. A value of 1% would mean
that the rounding of the ramp is near linear. A value of 50% would have 25% rounding at the start of the ramp
and 25% at the end of the ramp.
415 Accel Time 3
Default: 10.0 s
Range: 0.1 to 3200.0 s
Level 2
302 (Max Frequency)
401 (Ramp Select)
or Sequencer Configuration.
Note that extremely short acceleration times may result in nuisance fault trips.
MOTOR OVERHEATING
Do not use DC injection braking as a holding brake, or excessive motor
heating may result.
Failure to observe this instruction can result in equipment damage.
CAUTION
SURCHAUFFE DU MOTEUR
N’utilisez pas le fraingres CC comme frein de maintien car cela peut
entraîner une surchauffe excessive du moteur.
Si cette directive n’est pas respectée, cela peut entraîner des dommages
matériels.
