121
It displays the phase Z counting of the present ABZ or UVW encoder. The value increases or decreases by
1 every time the encoder rotates a round forwardly or reversely. You can check whether the installation of
the encoder is normal by viewing U0-45.

If it is set to any non-zero number, the password protection function is enabled. After a password has been
set and taken effect, you must enter the correct password in order to enter the menu. If the entered password
is incorrect you cannot view or modify parameters.
If A0-00 is set to 00000, the previously set user password is cleared, and the password protection function
is disabled.

The setting of parameter display mode aims to facilitate you to view different types of parameters based on
actual requirements.
If one digit of A0-08 is set to 1, you can switch over to different parameter display modes by pressing key
“QUICK”. By default, only the “frequency inverter parameter” display mode is used.
The display codes of different parameter types are shown in the following table.

The EM11 provides display of two types of individualized parameters: user-defined parameters and
user-modified parameters.
You-defined parameters are included in group “A1”. You can add a maximum of 32 parameters, convenient
for commissioning.
In user-defined parameter mode, symbol "u" is added before the function code. For example, b0-00 is
displayed as ub0-00.
In “User-changed parameter” mode, symbol "c" is added before the function code. For example, b0-00 is
displayed as cb0-00.
The User-changed parameters are grouped together in QUICK menu, which is convenient for on-site
troubleshooting.
