Hi, I'm working on a problem on a machine that uses 3 ELMO symphony SYM8/270R drives. A safety relay drops the mains power to the drives, but a 24v "keep warm" circuit keeps the processor alive to retain positions / memory etc. This 24v supply is present but the unit dies when mains power is removed - any clues ? should I take a peek inside ? The unit is now obsolete -anybody got one ?
