Had a fault 55 (no link between travel control and motor control). Had parm, ok and error led on vericon lit(yellow, green and leds). Was measuring 15vdc on power supply and when i unplugged the 2 ribbon cables at the bottom of the variocon board the voltage jumped back up to 24vdc. After powering down and unplugging the 12v battery for display and beeper, i powered back up and everything started working. Has anyone ever seen this before? Is there a manual for the drive and the variocon board and does anyone know of a place that repairs the VF33 BR drive?
