With power removed from the device: Check for continuity of the rectifier, L1, L2, L3 to DC+, and to DC-, these will indicate resistance in the order of Meg Ohms. A low resistance will indicate breakdown of the input rectifier, a short circuit. Inquire with a local repair agent with regard to repair, for small drives it is more cost effective to replace the unit. If there is any evidence of burning, or distorted capacitors, replace the drive complete, as this type of damage will stress local components making the unit unreliable. Inquire with your local repair agent for on site advice. AttachmentRectfiier testing, MM440.pptx (202 Downloads) |
