I have not yet received a response from ICOM, but I am beginning to understand the conditions when IC-PW1 becomes uncontrollable.
?
1, I have tried changing the USB port that connects the CI-V interface of the IC-PW1 to the PC, or changing the interface cable. it seems that the IC-PW1 becomes controllable in more cases, but not 100% controllable.
2, When IC-PW1 is powered off for a long time (for example, when it is powered on for the first time that day), DXLabCommander is unable to control IC-PW1 even if it is powered on. However, after that, when the power is turned on and off several times, the PW1 alert lights up and the IC-PW1 becomes controllable, and after that, the IC-PW1 remains controllable even if the power is turned on and off repeatedly.
3, Whether DXLabCommander can or cannot control IC-PW1 is determined when power is supplied to IC-PW1 by turning on the IC-7600 power supply, or when IC-PW1's POWER switch is turned on, in other words, when power for IC-PW1 control is turned on. 4, Once IC-PW1 is powered on, the power switch of IC-PW1 is turned on.
4, Once the IC-PW1 is in a controllable state and the power is turned on, it will remain so until the power is turned off. However, once the power is turned off, it is not known whether the IC-PW1 will be in a controllable state (PW1 alert lights up) the next time the power is turned on.
5, This phenomenon appears when DXLabCommander is used, but not when IC-7600 and IC-PW1 are directly connected. Also, I had previously connected IC-PW1 and SteppIR with IC-7600 and CI-V interface (improved version of CT-17) and IC-PW1 was controllable.

I wish I had a clue how to solve this problem, but this is what I can confirm now.
