Hey guys
I know someone has a simple solution for this problem. I have configured my controller in a very typical way. When the system is reset, on the screen, power is put to my amplifiers and at the same time power is put to my electro-magnetic brake on the z-axis to dissengage the brake. I have a heavy spindle thus the brake requirement when powered off. The problem is that the brake is dissengaging before the z-axis servo takes over holding the spindle up. How can I slow down the power to the brake by about 2 or 3 seconds to get some overlap? Can i use a thermister or a capacitor? Delay relay? I am putting power to the brake by switching on an 24vdc power supply that is only used for this brake. How are you guys solving this problem.
As always....thanks for any input.
Russ.
