Replacing the EPROM on the CUR module (upgrading to a new software version)
On setup and during servicing work, the current parameter settings in the logbook in Chapter 12 should be
saved For information on reading out the parameters changed from the factory settings easily, see Section
4.3.9.3 (saving the parameter values using DriveMonitor) and Section 4.3.9.8 (displaying modified parameters).
It should be checked that these entries are up-to-date before the EPROM is replaced because when the
electronics supply voltage is switched on again, the function "generate factory settings" is carried out
automatically (see Section 4.3.9.1). Then only the values of parameters P070 and P077 are retained.
The EPROM is located in slot D14 of module CUR.
The modules contain electrostatically sensitive devices. You must discharge your own
body before touching an electronic module. This is best done by touching a conductive
earthed object (e.g. a bare metal part of the control cabinet) directly beforehand.
Procedure for replacing EPROMs:
♦ Switch off electronics supply voltage
♦ Undo fixing screws for module CUR above and below the insertion/removal aids
♦ Remove the module from the electronics box carefully with the help of the insertion/removal aids.
♦ Remove old EPROM carefully from the socket and replace it with a new EPROM. It is important to ensure
that the EPROM is mounted the right way round (pin 1 aligned correctly) and that pins are not bent
♦ Slide module into the electronics box carefully in the guide rails as far as the stop
♦ Screw the module into place again using the fixing screws
♦ After switching the electronics supply voltage on again, wait until the function "generate factory setting" is
complete. Then restore the parameter values in accordance with the logbook or reload the values saved
using DriveMonitor into the unit.
♦ If the parameters are restored in accordance with the logbook, circuit identification (see Section 4.3.9.7)
must be carried out (due to special parameter P772).

Common Rectifier Operating Instructions
The EPROM must only be replaced by qualified persons. The EPROM must
not be removed or inserted under a live voltage.
Non-observance of warning notices can result in death, severe personal injury
or considerable property damage.
