Parameterization procedure

Parameterization is the process of changing setting values (parameters) via the operator panel,
activating converter functions or displaying measured values.
Parameters for the basic converter are called P, r, U or n parameters. Parameters for an optional
supplementary board are called H, d, L or c parameters.
The basic unit parameters are displayed first on the PMU, followed by the technology board
parameters (if such a board is installed). It is important not to confuse the parameters of the
optional S00 technology software of the basic unit with the parameters of an optional supplementary
board (T100, T300 or T400).
Depending on how parameter P052 is set, only some parameter numbers (see Section 11,
Parameter List) are displayed.
7.3.1

Parameter types

Display parameters are used to display current quantities such as the main setpoint, armature
voltage, setpoint/actual value difference of speed controller, etc. The values of display parameters
are read-only values and cannot be changed.
Setting parameters are used to both display and change quantities such as the rated motor
current, thermal motor time constant, speed controller P gain, etc.
Indexed parameters are used to both display and change several parameter values which are all
assigned to the same parameter number.
7.3.2 Parameterization on simple operator control panel
After the electronics supply voltage has been switched on, the PMU is either in the operational
display state and indicating the current operating status of the SIMOREG 6RA70 (e.g. o7.0), or in
the fault/alarm display state and indicating a fault or alarm (e.g. F021).
Operational states are described under parameter r000 in Section 11 and the fault and alarm
messages in Section 10.
1. To reach the parameter number level from the operational display state (e.g. o7.0), press the P
key and then the <Up> or <Down> key to select individual parameter numbers.
2. To reach the parameter index level (for indexed parameters) from the parameter number level,
press P and then the <Up> or <Down> key to select individual indices.
If you press P when a non-indexed parameter is displayed, you go directly to the parameter
value level.
3. To reach the parameter value level from the parameter index level (for indexed parameters),
press P.
4. On the parameter value level, you can change the setting of a parameter value by pressing the
<Up> or <Down> key.
CAUTION!
Parameters can be altered only if the following conditions are fulfilled:
− The appropriate access authorization is set in key parameter P051, e.g. "40" (see Section 11,
"Parameter List").
− The converter is the correct operational state. Parameters with characteristic "offline" cannot be
changed when the converter is in the "Run" (online) state. To change parameters with this
characteristic, switch the converter to the ≥o1.0 status ("Ready").
− The values of display parameters can never be changed (read only).
