Learning Basic Features
Motor Output Voltage Adjustment
Output voltage settings are required when a motor’s rated voltage differs from the input voltage to
the inverter. Set the voltage to the motor’s rated operating voltage. The set voltage becomes the
output voltage at the inverter’s base frequency. If bA.15 (motor rated voltage) is set to 0, the
inverter corrects the output voltage based on the input voltage in the stopped condition. If the
frequency is higher than the base frequency, when the input voltage is lower than the parameter
setting, the input voltage will be the inverter output voltage.

Start Mode Setting
Select a start mode to use when the run command is applied with the motor in the stopped
condition. Select 0 (acceleration start) or 1 (DC Brake Start). Excitation current (Pre-Excite) can also
be applied by activating a digital input.
Accelerating Start
Acceleration start is the typical acceleration mode used when starting a motor from a stopped
condition. If there are no other settings applied, the motor accelerates to the frequency reference
when the run command is applied.

DC Braking At Start
This start mode supplies a DC voltage for a set amount of time to provide DC braking before an
inverter starts to accelerate a motor. Use when the motor is rotating due to its inertia, DC braking
will stop the motor, allowing the motor to accelerate from a stopped condition. DC braking can
also be used when a mechanical brake is connected to a motor shaft and constant torque is
required after the release of the mechanical brake. DC braking at start will not operate if the
control mode (dr.09) is set to IM Sensorless.
