 Notation Used in this Manual
 Notation for Reverse Signals
The names of reverse signals (i.e., ones that are valid when low) are written with a forward slash (/)
before the signal abbreviation.
Notation Example
BK
is written as /BK.
 Notation for Parameters
The notation depends on whether the parameter requires a numeric setting (parameter for numeric
setting) or requires the selection of a function (parameter for selecting functions).

Parameters for Numeric Settings
Notation Example
n.0
(default setting)
Do not detect preventative maintenance warnings.
n.1
Detect preventative maintenance warnings.
Parameter Meaning When Enabled Classication
After restart Setup
This is the setting range for the parameter.
Pn00F
Parameter number
The notation “n.” indicates a parameter for selecting functions.
Each  indicates the setting for one digit.
The notation shown here means that the first digit from the right is set to 1.
If All Axes is given here, the parameter applies to both axes A and B.
If you change the setting, the new setting will be applied to both axes.

Parameter number
If All Axes is given
here, the parameter
applies to both axes A
and B.
If you change the
setting, the new setting
will be applied to both
axes.

Position Torque
The control methods for which the parameters apply are given.
Speed
: Speed control : Position control : Torque control
This is the
parameter setting
before shipment.
This is when any
change made to the
parameter will
become effective.
This is the parameter
classication.
This is the minimum
unit (setting increment)
that you can set for
the parameter.
This column explains the
selections for the function.
