Speed Control
Section 10-5
Pn002.0 is used to select the function of the option command value for speed
control. The option command value for speed control is described in the fol-
lowing pages.
The data length for Pn002.0 is the set value specified to transfer Pn002
(including Pn002.0) when transferring Servo Parameters.
Pn502 is set as the detection threshold of the Zero Speed Flag (word b+1, bit
08) in the Axis Operating Input Memory Area. Pn503 is set as the detection
width of the Speed Conformity Flag (word b+1, bit 07) in the Axis Operating
Input Memory Area.

When using G5-series Servo Drives, the option command value 1 can be
used as the torque limit command value or torque feed forward command
value by setting the Servo Parameter
Torque Limit Selection (Pn521).
When using G-series Servo Drives, the option command value 1 can be
used as the torque limit command value or torque feed forward command
value by setting the Servo Parameter
Torque Limit Selection (Pn003).
When using W-series Servo Drives, the option command value 1 can be
used as the torque limit command value or torque feed forward command
value by setting
Torque Command Input Change in Servo Parameter Func-
tion Selection Application Switch 2 (Pn002.0).
