Auto Tuning
A series of operations to rotate the motor, measure the load inertia/load mass, and set up the
parameters of the control section on its own.
Axial load (Forward, Reverse)
The motor is fastened to the base and a uniform dead load is applied to the rotor's load
mounting area in the axial direction. The "axial load" is the maximum load when all
component parts of the motor are within the elastic deformation zone. When the load is
removed, all the component parts must be restored to their original states. Note that the
forward axial load refers to contracting the motor in its axial direction, and the reverse axial
load refers to adding a load to the motor in its expansion direction.
Axial stiffness (Forward, Reverse)
This refers to the axial displacement per unit axial load when the motor is fastened to the
base and a uniform dead load is added to the rotor's load mounting area in the axial direction
within the axial load. "Axial displacement/axial load" must be linear. Forward Axial stiffness
refers to contracting the motor in its axial direction, and the reverse Axial stiffness refers to
adding a load to the motor in its expansion direction.
AXIS
Motor axis
Axis Command Unit
The common unit set up by the #112 parameter
B
Backup
Storing data from the drive to an upper device (PC, operation display pendant). Same as
upload.
Basic Data
Maker information of the drive/motor, which cannot be manipulated by users. This data
cannot be erased by all reset operations.
BCD
Binary coded decimal
BIN
Binary
Binary Code
A numerical code in binary notation
Bit AND
AND for each bit. This is used to extract several bits.
Bit EXOR
Exclusive OR for each bit
Bit OR
OR for each bit. This is used to turn ON several bits.
Block
Logic I/O and physical (hard) I/O are internally managed in 8-bit units, each of which is called
a block. I/O settings are also performed in block units.
Branching
To branch. Table operation - condition branching
