10.3 Settings and Commands
Required for Running the Inverter
• Want to turn the motor.
• To turn the motor, configure the following settings:
Basic setting for motor
• Set the following parameters in accordance with the
plate of motor. Set the data indicating the basic
characteristics of motor.
*) See "12.3 Basic Settings for Motor” for details.
Setting for protection of motor
• The motor may be burned if a large current keeps
on flowing in the motor; the setting therefore must
be performed appropriately.
*) See "12.7 Temperature Protection of Motor” for
details.
Setting for activating the motor
• The voltage output of the inverter requires not only
an operation command but also a frequency
command. In the initial state, a main speed
command is used as a frequency command.
Item Parameter
First main speed command selection [AA101]
First operation command selection [AA111]
Main speed command [FA-01]
*) For details, see “12.4 Select a Frequency
Command”, “12.5 Selecting a Operation Command”
and “Chapter 11 Examples of Settings by Operation
Command Destination”.
• This article explains the settings for operation.
Carefully read Safety Instructions before handling
the inverter.
Settings for motor control
• Set the motor control method.
• For changing to the mode of driving an SM (PMM),
you need to change the control method.
Item Parameter
First control mode [AA121]
*) For details, see "12.9 Select motor control method
in accordance with motor and load".
• When driving an SM (PMM) or using other motors
than Hitachi's standard motors, or setting long
wiring length, you need to set up the following
motor constants:
• For induction motor IM
Item Parameter
First IM motor constant R1 [Hb110]
First IM motor constant R2 [Hb112]
First motor constant L [Hb114]
First IM motor constant I0 [Hb116]
