Parameter Details
Explanation of Set Values
It depends on the control mode.
When the control mode is set to speed control/torque control, the torque command input is set to
analog input 2.
If analog input 1 is used for the speed limit, the speed control scale is set in Pn302. The applied
voltage is converted to a speed limit as shown below when the analog speed limit is in effect.
Speed limit [r/min] = |Pn302 × Input voltage [V]|
An example is shown below for Pn302 = 500 [r/min/V]
