Hi, I was chanting the keypad on my johnford vmc 550. Machine was on but emergency switch was pressed in. Somehow fee keys on the new keypad got pressed during the process and I started getting servo 434 and 437 alarm. Can some one help please ? Thanks.

Probably best to have the power off in general when servicing as you imply. Did you try turning everything off and cutting the power at the breaker for a while to reset? Does it still work? Do you need to try using the old equipment you replaced?
 
I don't think you have asked the question properly. jonford cnc is the machine hardware. Your controller is a fanuc that is very common. What you should be looking for is someone who has experience operating the fanuc controller. That same controller will be found in many machines such as matsura and mori siki. The matsura repair guys in calgary could fix your machine for sure.
