Range Description
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 EXTENDED
SETTING as
described in
section
6.4.4
page 42.
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 HRVS-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
100-700% by
using the
EXTENDED
SETTING as
described in
section
6.4.4
page 42.
Sets motor’s CURRENT LIMIT 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
.
