With Hirata-san and Ikeda-san

We unjammed the the jammed picomotor. We

• Locked the BF damper
• Locked the BF case to the security structure.
• With an Allen key we turned the nob of the picomotor around a little bit and then Ikeda-san moving remotely from the medm screen. We saw it moving.

The other BF picomotor was not moving. We disconnected some cables and checked them with the multimeter but we didn't find any obvious problem. After we reconnected the cables we tried moving the picomotor using the medm screen and it seemed to move, but it makes a low pitch sound rather than the high pitch sound picomotors usually do. We have experienced a similar problem in one of the Type-B suspensions, but I can't find the klog.
