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

If you find a problem about coil-magnet actuator, 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.
