5.2
Setting procedure of Vector control (speed control)
Operating procedure
1.
Perform wiring properly. (Refer to the Instruction Manual (Connection).)
Install a Vector control compatible option.
2.
Set the applied motor and encoder ( Pr.71, Pr.359, Pr.369 ). (Refer to page 340 , page 365 .)
3.
Set the overheat protection of the motor ( Pr.9 ). (Refer to page 238 .)
When using the SF-V5RU or a motor equipped with a thermal sensor, set Pr.9 = 0 A. For details on connecting a
motor equipped with a thermal sensor, refer to the Instruction Manual (Connection).
4.
Set the motor capacity and number of motor poles ( Pr.80, Pr.81 ). (Refer to page 97 .)
V/F control is performed when the setting is "9999" (initial value).
5.
Set the rated motor voltage and the rated motor frequency ( Pr.83, Pr.84 ). (Refer to page 345 .)
6.
Select the control method ( Pr.800 ). (Refer to page 97 .)
Select Pr.800 = "0" (speed control) or "2" (speed/torque switchover) to enable speed control.
7.
Set the operation command. (Refer to page 212 .)
Select the start command and speed command.
8.
Set the torque limit ( Pr.810 ). (Refer to page 114 .)
9.
Perform the test operation.
As required
• Perform offline auto tuning (Pr.96) . (Refer to page 345 .)
• Select online auto tuning ( Pr.95 ). (Refer to page 362 .)
NOTE
• Under Vector control, the magnetic flux observer is enabled to estimate or measure the flux within the motor using the current
running through the motor and the inverter output voltage. This improves the torque accuracy since the flux of a motor can be
accurately estimated and optimum characteristics can be obtained without being affected by temperature change in the
second resistor.
• The speed command setting range under Vector control is 0 to 400 Hz.
• The carrier frequency is limited during Vector control. (Refer to
page 184 .)
