== LVDTs ==

=== Polarity & Calibration Factor ===
 * V: postive means that the LVDT outputs positive counts when TMS-VIS moves upward, and so the calibration factors are set.
 * H: postive means that the LVDT outputs positive counts when TMS-VIS moves positive yaw (counter clock wise from top view), and so the calibration factors are set.
||'''Sensor'''|| Serial#|| polarity || calibration factor [um/cnt]||
|| LVDT V1 ||#6 ||-1 ||0.1374  ||
|| LVDT V2 ||#8 ||+1 ||0.1463  ||
|| LVDT V3 ||#9 ||+1 ||0.1456  ||
|| LVDT H1 ||#10 ||-1 ||0.1356  ||
|| LVDT H2 ||#11 ||-1 ||0.1371  ||
|| LVDT H3 ||#12 ||+1 ||0.1473  ||



== Actuator coils ==
Be careful! The pin assignment in the Dsub shell or the signal phases would be different from the below, as I needed to once detach the pins when I installed the coils (Akutsu). Note that newly four actuator coils have been made for TMS-VISY after JGW-T1800846.

 * Tanioka-kun's efforts in 2019


=== Polarity & Calibration Factor ===
 * V: postive means upward (TMS-VIS moves in upward by inputting positive value to the act coils from MEDM)
 * H: positive means plus yaw (TMS-VIS moves in counter clock wise from top view by inputting positive value to the act coils from MEDM)
