2.4.3 Unlocking the controller with a MasterPin
Every controller has an individual master password called "MasterPin". By entering the MasterPin, a
controller inhibited by the password mechanisms can be reset to the delivery status.

How to restore the delivery status:
1. Inhibit the controller if it is enabled, e.g. via the C00002/16 device command.
2. Enter the MasterPin in C00505/1 .
• The MasterPin comprises the last 6 digits of the serial number of the memory module.
3. Execute "Check MasterPin" device command C00002/28 = "1: On / start"

Stop!
When the MasterPin is used, the parameter set is reset to the Lenze setting both in the
controller and in the memory module!
• This results in a permanent loss of the customised parameterisation that must be
recreated!
• A reset to the Lenze setting can result in unforeseen level changes at the I/O terminals
(e.g. brake control)!
