000 ROAX ROTX
Size : 1 byte/bit type
Standard value :0
ROTX Specifies a rotation axis. When exercising speed control,
set this bit to 1.
0 : Linear axis
1 : Rotation axis
ROAX Specifies the rotation axis roll--over function. When
exercising speed control, set this bit to 1.
0 : Disables the function.
1 : Enables the function.

080 Current limit value (TQLIM)
Size : 2 bytes
Valid data range : 0 to 7282
When exercising speed control, set the maximum value 7282 beforehand.

100 Load inertia ratio (LDINT)
Size : 2 bytes
Valid data range : 0 to 1024
Set the ratio of the machine load inertia to the motor inertia, using a value
obtained from the formula below as a guideline.
Load inertia ratio = (machine load inertia/motor inertia) × 256
If a value obtained by calculation exceeds 500, however, set 500. When
a value is set in this parameter, the velocity loop gain is set to PK1V, and
PK2V is increased by a factor of (1 + LDINT)/256.
