Sometimes upon turning on main power I get an AL-04 alarm on the spindle drive. Turning off the breaker and trying again will make it go away and no alarm. I'm running off Phase perfect and my tech guy says it could be drive not liking converted 3 phase power. Is he right or do I have a drive going bad or could I possibly have a faulty power on/off switch? Tonight I had to re-try 3 times for the alarm to go away.
