Differences between revisions 9 and 11 (spanning 2 versions)

Each MC suspension has 4 coils and 2 pico-motors (pitch, yaw).

Each iKAGRA ETM suspension has 4 coils and 4 pico-motors (pitch:1-6, yaw:2-7, z:3-8, y:4-9) connected.

If the coil-magnet actuator has a problem, please check 2 things.

1. Coil drivers in particular for Y-end had a loose connection with power line (-18V, -15V).

Please check the LED on coil driver. If the LED is out, try to fasten the power line.

2. Sometimes watchdog? system stop the output current from the coil driver in order to protect mechanical system.
