(2) Phase initialization mode: SW method 1
When SW method 1 is used, Hall sensor is not needed and the motor only needs to move for a small
distance to complete phase initialization. Two parameters, st_cg and st_vpg, must be adjusted
before using SW method 1, please refer to chapter 10. If the load is changed, these parameters
need to be adjusted again. When using operation mode other than stand-alone mode, external
command is suggested to be sent after the controller receives servo ready signal from the servo
drive. If servo ready signal cannot be received by the controller, wait at least three seconds before
sending external commands (For Lightening 0.181 or later version).
Note:
For Lightening 0.180 or previous version, wait at least two seconds before sending external commands.

Absolute encoders, such as EnDat, BiSS and Nikon are used to perform phase initialization.
