2.4.4 Unlocking the inverter with a MasterPin
Every inverter has an individual master password called "MasterPin". By entering the MasterPin, an
inverter inhibited by the password mechanisms can be reset to the delivery status.
How to restore the delivery status:
1. Inhibit the inverter 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
inverter 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)!
