 Common Specifications
The following specifications apply to both 200 V and 400 V Class Inverters.
* 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 66 Hz (for PRG 103, 132 Hz).
