Setting Procedure Of Vector Control (Speed Control) - Mitsubishi Electric 800 Series Instruction Manual (Function

5.2

Setting procedure of Vector control (speed control)

Vector Vector Vector
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
3.
Set the overheat protection of the motor (Pr.9). (Refer to
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
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
6.
Select the control method (Pr.800). (Refer to
Select Pr.800 = "0" (speed control), "2" (speed/torque switchover), or "4" (speed/position switchover) to enable
speed control.
7.
Set the operation command. (Refer to
Select the start command and speed command.
8.
Set the torque limit (Pr.810). (Refer to
9.
Perform the test operation.
As required
• Perform offline auto tuning (Pr.96). (Refer to
• Select online auto tuning (Pr.95). (Refer to
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
