410 DB Config Default: DB Internal
Range: 0-2
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.
(Note: Size 0 models cannot have an external brake added.)
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
No Dyn Brk Dynamic braking circuit disabled
Int-ARCTIC When DB Config is configured to “Int-ARCTIC,” dynamic braking becomes active if the drive temperature
drops below -7 degrees C. When the DB becomes active, an “ARCTIC Mode” warning flashes on the
keypad. If the drive 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 drive heats up after being below -10
degrees C, the drive must meet the following criteria before operating again:
a) Drive temperature must be above -9 degrees C, and
b) Drive 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 drive 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.

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.
