Tfx Errorcode: [03502] The focus control mode is in progress


Service Information	The commands implemented by the exposure head are non-blocking. As a result, the command to configure the focus control mode will only initiate the focus control mode. The host ( or user ) is required to wait until the focus control mode is complete before issuing the next command ( affecting the focus ). This error code indicates that configuration of the focus control mode is in progress.
	For example, the host ( or user ) will initiate the "Learn" focus control mode to learn focus. If successful, the host ( or user ) can poll the focus state. This error code indicates the "Learn" focus control mode is in progress and any other error code indicates the "Learn" focus control mode is complete. Once the focus has been learned, the host ( or user ) can issue the next command.
	Note that the command to configure the focus control mode can be aborted when requested by the host ( or user ) or when required by the fault handler.
Operator Action	Wait for completion of the focus control mode.
Causes	The focus control mode is in progress.
