YASKAWA FSDrive-MV1S - Making Application Settings

Trial Operation Procedures
4-7
* 1. Factory setting depends on the Inverter capacity.
* 2. Setting range is between 10 and 200% of the Inverter rated output current.
* 3. For fixed output motors, set the base speed value.
* 4. For inverter motors or for specialized vector motors, the voltage or frequency may be lower than for general-purpose motors. Always confirm the information 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 frequency in T1-05 to ensure accuracy.
* 5. The settings that ensure stable vector control are between 50 and 100% of the Inverter rating.
Refer to Page 3-10 for Digital Operator displays during autotuning.
Precautions When Setting Constants Using Precise Data
When performing autotuning by setting the constants to the values noted on the motor test report or design
data, the contents of data to be set for autotuning differs as shown in the table below.
 Making Application Settings
Set the constants as required in advanced programming mode (ADV will be displayed on the LCD screen). All
constants that can be set in quick programming mode can also be displayed and set in advanced programming
mode.
Setting Examples
Two setting examples for specific requirements are given below.
• To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0.
