Hello, we are sorry for any inconvenience you experienced. May I know what is the SDK command sending frequency you are currently using? If you use a lower command sending frequency, with the current motor firmware, the motor will not respond, considering that the motor may be stuck and not smooth. Our future firmware will continue to optimize it.
At present, it is recommended that you refer to the SDK documentation on the official website, and keep the command sending frequency at 100Hz. Thank you.
Hi,
Thank you for the information. The movement and the reply frame for focus motor position control command (CmdSet 0x0E, CmdID 0x12, sub ID 0x01) of each focus motor model looks like the following.
- DJI RS Focus Motor (older version) : motor will be respond, even if it is a lower command sending frequency. no reply frame (as described in the SDK document)
- DJI RS Focus Motor (2022, firmware version 00.03) : motor will be respond, even if it is a lower command sending frequency. it has a reply frame (why?)
- DJI RS Focus Motor (2022, firmware version 01.00) : command must be sent at 100Hz. it has a reply frame, too
My guess is that some problems are due to reply frames being sent that shouldn't be sent?
Thank you. |
