* 1. Rotational autotuning must be performed to ensure obtaining the specifications given for flux or open-loop vector 1/2 control.
* 2. When connecting a Braking Resistor or Braking Resistor Unit, set L3-04 (Stall prevention selection during deceleration) to 0 (disabled). Stopping may not be pos-
sible in the specified deceleration time if this function is not disabled.
* 3. The maximum output frequency for open-loop vector 2 control is 60 Hz (for PRG: 103 , 120 Hz).
