* 1. Not normally displayed. Displayed only when a motor switch command is set for a multi-function digital input (one of H1-01 to H1-05 set to 16).
* 2. The factory setting depends on the Inverter capacity. Values are given for a 200 V class, 0.4 kW Inverter.
* 3. The setting range is 10% to 200% of the Inverter capacity.
* 4. For V/f control, the only setting that is possible is 2 (stationary autotuning for line-to-line resistance only).
* 5. For fixed output motors, set the base speed value.
* 6. For inverter motors or for specialized vector motors, the voltage or frequency may be lower than for general-purpose motors. Always confirm the infor-
mation on the nameplate or in test reports. If the no-load values are known, input the no-load voltage in T1-03 and the no-load current in T1-05 to
ensure accuracy.
* 7. The settings that will ensure stable vector control are between 50% and 100% of the Inverter rating.
