Re: servo brake problem

Hello,
Logically, if power were removed from the solenoid, during an E-
stop for example, the spindle should be in brake mode. When the
solenoid coil is charged, the spindle should be free. Just my guess,
mind you.

Can you check and see if there is continuity through the coil? No
electricity can flow through the coil if it's broke.

If you are sure you have the right voltage etc..., maybe it's simply
stuck, or binding mechanically. Did it work correctly recently?
