Sets the motor’s 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 Starting
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 Starting Voltage is set its maximum value, this
displays changes to Starting Current.
When Starting Current is set the ASTAT-XT causes current
ramp instead of voltage ramp.

The range of the Starting Voltage can be extended to 5-80% by using the EXPANDED SETTING as described in section 5.5.5
page 50.
