Setting Procedure Of Vector Control (Position Control) - Mitsubishi Electric FR-A800 Series Instruction Manual

5.5.2 Setting procedure of Vector control (position
control)
Vector Vector Vector
 Using an induction motor
Operating procedure
1.
Perform secure wiring. (Refer to
Install a Vector control compatible option.
2.
Set the option to be used (Pr.862).
Set Pr.862 Encoder option selection according to the option to be used. (Refer to
3.
Set the motor and the encoder (Pr.71, Pr.359 (Pr.852), Pr.369 (Pr.851)). (Refer to
4.
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.
5.
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).
6.
Set the rated motor voltage and frequency (Pr.83, Pr.84). (Refer to
7.
Select the control method (Pr.800). (Refer to
Set Pr.800 = "3" (position control), "4" (speed - position switching), or "5" (position - torque switching) to enable
position control.
8.
Select the position command source (Pr.419).
• For position command given by point table, set Pr.419 = "0 (initial value), 10, 100, or 110" to set the positioning
parameters (Pr.465 to Pr.494, Pr.1222 to Pr.1281). (Refer to
• For position command given by inverter pulse train input, set Pr.419 = "2" to select a pulse train type for
commands (Pr.428). (Refer to
• For position command given from the positioning module of the programmable controller, set Pr.419 = "1" to
select a pulse train type for commands (Pr.428). (Refer to
9.
Perform the test operation.
As required
• Set the electronic gear. (Refer to
• Set the position adjustment parameters. (Refer to
• Adjust the position control gain. (Refer to
• Set the torque limit. (Refer to
NOTE
• The carrier frequency is limited during Vector control. (Refer to
• Refer to the Instruction Manual of each option for details on Vector control using the FR-A8APR, FR-A8APS, or FR-A8APA.
• To perform operation in position control mode, the Pre-excitation/servo ON (LX) signal needs to be turned ON. To assign the
LX signal, set "23" in any of Pr.178 to Pr.189 (Input terminal function selection).
