Current Limit
400% of Im
100-700%
% of
Motor
Current
Sets the motor’s highest current during starting.
A setting that is too high will increase the current drawn from
mains and speed up acceleration.
A setting that is too low may prevent the motor from
completing the acceleration process and reaching full speed. In
general, this setting should be set to a value that is high enough
to prevent stalling.
Current Limit
is limited to the value of:
<400x(
Starter Current
/
Motor Current
)>
with a minimum setting of 300% and a maximum
setting of 700%.
Note:
Current Limit
does not operate during
RUN
and
SOFT

.
Ramp UP Time

1-30
sec.
Sets Ramp UP Time of the motor.
Determines the motor’s voltage
Ramp UP Time
, from initial to
full voltage.
It is recommended to set the
Ramp UP Time
to the minimum
acceptable value (approx. 5 sec).
Notes:
Since
Current Limit
overrides
Ramp UP Time
, when
Current Limit
is set low, the starting time will be longer
than the
Ramp UP Time
setting.
When the motor reaches full speed before voltage reaches
nominal,
Ramp UP Time
setting is overridden, causing voltage
to quickly ramp-up to nominal.
Using
Soft Start Curve 1, 2, 3
prevents quick ramp
up.

The range of the
Ramp UP Time
can be extended to 1-90 sec. by using the EXPANDED SETTING as described in section
5.5.5
