Chapter 16 PLC Function ApplicationsMH300
16-8 Explanation of Each PLC Mode Control (Speed, Torque)
Tor
que mode must be based on FOC vector control, and speed mode can also support FOC
vector control. So for torque mode or FOC-based speed mode, you must complete the motor
parameter auto-tuning in advance; otherwise, the control cannot be completed.
In addition, there are two types of motors: IM and PM. The IM motor only needs to perform
motor parameter auto-tuning, while PM motor must complete auto-tuning of the motor origin offset
angle after the motor parameter auto-tuning is complete. Refer to Pr.05-00 for details.
※ If the PM
motor is one of the Delta ECMA series, you can directly input the motor parameters
according to the servo motor catalog. There is no need to perform motor parameter auto-tuning.
