INITIAL VOLTAGE

INITIAL CURRENT
100 %
10-50%
After reaching
50% the
display
changes to:
INITIAL
CURRENT
100-400%.
Note:
The range of
the INITIAL
VOLTAGE can
be extended to
5-80% by using
the
EXPANDED
SETTING as
described in
section
6.5.5
page 58.
Sets motor’s
INITIAL
STARTING
VOLTAGE.
The motor’s
torque
is directly
proportional to
the square of the
voltage.
This adjustment also determines the inrush
current and mechanical shock. A setting
that is too high may cause high initial
mechanical shock and high inrush current.
This can occur even if CURRENT LIMIT is
set low because the INITIAL VOLTAGE
setting overrides the CURRENT LIMIT
setting.
A setting that is too low may result in
prolonged time until the motor starts to turn.
In general, this setting should ensure that
the motor starts turning immediately after
start signal.
Note:
When INITIAL VOLTAGE is set its
maximum value, this displays changes to
INITIAL CURRENT.
When INITIAL CURRENT is set the RVS-
DN causes current ramp instead of voltage
ramp.
CURRENT LIMIT
400% OF FLA
100-400%.
Note:
The range of
the CURRENT
LIMIT can be
extended to
100-500% by
using the
EXPANDED
SETTING as
described in
section
6.5.5
page 58.
Sets motor’s
highest curr
ent
during starting.
A setting that is too high will increase the
current drawn from mains and faster
acceleration.
A setting that is too low may prevent the
motor from completing acceleration process
and reaching full speed. In general, this
setting should be set to a value that is high
enough to prevent stalling.
Note:
CURRENT LIMIT does not operate during
RUN and SOFT STOP.
