DocumentDocumentInstallation Instructions Memory Module Replacement VLT® DriveMotor FCP 106 & FCM 106 Introduction The instructions provide information about the replacement of memory module (ordering number: 134B0791). A memory module is a component that stores motor and pump data, as well as firmware and parameter settings of a frequency converter. If a frequency converter malfunctions, the motor and pump data, firmware, and parameter settings on this frequency converter can be copied to new frequency converters of the same power sizes. Doing this saves the time for setting up the frequency converters for the same applications. A memory module is pre-installed on the frequency converter. The data and parameter settings on a memory module are encoded files that are protected from direct viewing. To access files in a memory module, or transfer files between a memory module and a PC, a memory module programmer is required. It is not included in this package and needs to be ordered separately (ordering number: 134B0792). 1 Memory module 2 Status indicator light 3 Socket for memory module 4 Memory module programmer 5 USB Type-B receptacle Illustration 1.1 Memory Module and Memory Module Programmer Items Supplied Ordering number Items supplied 134B0791 Memory module Safety Instructions Only qualified personnel is allowed to install or operate this equipment.

Failure to wait the specified time after power has been removed before performing service or repair work can result in death or serious injury. · Stop the motor. · Disconnect AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DClink connections to other frequency converters. · Disconnect or lock PM motor. · Wait for the capacitors to discharge fully. The minimum duration of waiting time is specified in Table 1.1. · Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.
