ANTRIEBSTECHNIK
When a password is entered you can switch between each parameter level. The
parameter levels set by ud.0 only apply to the inputs via keyboard and LED-display.
The independent parameter levels for operation with serial interface or with Dual-Port-
Ram protocol are preset by parameter ud.1. The parameters are:
Password Password Levels
100 CP - READ ONLY
200 CP - ON
440 APPLICATION
500 DRIVE - MODE
The significance of each password level is described in Chapter 4.4 „Password
Structure“.
When the FUNCT key is pressed and there is a change into ud.0, then the current
password level is shown first. To enter a new password use the UP/DOWN key. The
new password must be confirmed with ENTER. Thereafter the actual password level is
shown again.
The keyboard password can also be preset by the serial interface. This input is the
same as the input via keyboard. This means that after setting the password with bus
the LED display shows the actual keyboard password level and changes to ud.0 and/or
cP.0 by confirming FUNCT.
Presets the password levels for operation with serial interface and/or Dual-Port-Ram
protocol.
Password levels CP-ON, APPLICATION and SUPERVISOR are possible. The
passwords and the significance of the password levels are the same as those of the
keyboard password. The bus password is not visible during keyboard operation.
The start parameters select the parameter, which is displayed after the inverter is
switched on. In ud.2 the desired parameter group is set and in ud.3 the desired
parameter number. The parameter set is always set at 0. If a parameter is set in ud.3
that does not exist, the inverter starts with the next highest parameter number.
When the inverter is switched on a password level < 3 is active, meaning display of the
user defined parameter groups. The setting of ud.2 is ignored. ud.3 then specifies the
parameter number of the cP-parameter, whose value should be displayed at start-up.
If this parameter is not available, then cP.0 is shown.
The parameter storage (EEPROM) of the unit does not permit an unlimited number of
write cycles. To increase the life expectancy of the parameter memory set ud.4 at 0
(AUTO-SAVE) .
Thereafter all parameters written via Bus are not stored!
Switching off the parameter storage is only necessary when the inverter continuously
receives new parameters via bus and exceeds the maximum number (1 million) of
write cycles.
Note: Parameter changes done via keyboard are always stored!
