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

7.2
Setting procedure of Vector control (position
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 motor and the 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 other motor equipped with a thermal sensor for overheat protection, 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 frequency (Pr.83, Pr.84). (Refer to
6.
Select the control method (Pr.800). (Refer to
Select Pr.800 = "3" (position control), "4" (speed/position switchover), or "5" (position/torque switchover) to enable
position control.
7.
Setting of position command given by point table
• Set the positioning parameters (Pr.465 to Pr.478, Pr.1222, Pr.1223, Pr.1225 to Pr.1227, Pr.1229 to Pr.1231,
Pr.1233 to Pr.1235, Pr.1237 to Pr.1239, Pr.1241 to Pr.1243, Pr.1245 to Pr.1247, Pr.1249). (Refer to
163.)
8.
Set parameters related to home position return (Pr.511, Pr.1282, Pr.1283, Pr.1285, Pr.1286). (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
• Set the functions of output terminals. (Refer to
NOTE
• Position control is available only when an induction motor with an encoder is used. When a PM motor is used, position control
under PM sensorless vector control is not available.
• The carrier frequency is limited during Vector control. (Refer to
• 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 parameter from Pr.178 to Pr.189 (Input terminal function selection).
• Ignoring the home position (servo ON position as the home position) is initially selected for the home position return method.
