Depends on speed unit.
Description
Stores the feedback speed.
The value is determined by the moving average time constant (fixed parameter 42) and unit set from the difference with
the Machine Coordinate Feedback Position (monitoring parameter IL

16) in each scan.

The setting unit for this parameter depends on the Speed Units (OW

03, bits 0 to 3), but the result of
applying the speed unit setting is not shown here.

Depends on the Torque Unit
(OW

03 bits C to F).
Description
Stores the value of the torque reference.
The Torque (Thrust) Reference Monitor is achieved using the Servo command expansion area and can be executed only
with the MECHATROLINK-II, 32-byte Mode communication method.

The setting unit for this parameter depends on the Torque Unit Selection (OW

03, bits C to F), but
the result of applying the torque unit setting is not shown here.

Description
Stores the data of the specified fixed parameter number.
This parameter stores the data of the fixed parameter when the Read Fixed Parameter (FIXPRM-RD) is selected in the
Motion Subcommand (setting parameter OW

0A).
