Note1) Selecting 5 (Panel input) activates the control panel torque reference .
Note2) Use 2 phases input type sensor when torque control is operated by vector control
with a sensor.
Note3) For sensorless vector control, "forward power running ⇔ reverse regeneration"
and "forward regeneration ⇔ reverse power running" cannot be operated.
Use vector control with a sensor (2 phases) for these uses.

6.21.2 Torque reference filter

 ：Torque reference filter
・Function
When a motor drives a load with large inertia or when the gain cannot be increased
because the machine is not rigid enough to allow it, the motor sometimes vibrates. In
such cases, this filter is used to reduce the vibration. The smaller the set value, the
larger effect the filter can exert. (The response of the motor decreases to reduce the
vibration.)
