8.3Parameterization procedure

Parameterization is the process of changing or setting parameter values, activating converter functions, or displaying measured values with the operator panel.

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 S00 technology software of the basic unit with the parameters of an optional supplementary board (T400).

Depending on how parameter P052 is set, only some parameter numbers are displayed.

8.3.1Parameter types

Display parameters (r, n, d, and c), are used to display current quantities such as the main setpoint, armature voltage, feedback signals, outputs of controller, etc. The values of display parameters are read- only values and cannot be changed.

Setting parameters (P, U, H, L), are used to both display and change parameter quantities such as the rated motor current, thermal motor time constant, speed controller P gain, etc.

Indexed parameters (P, U, H, L), are used to both display and change several parameter values which are all assigned to the same parameter number but identified by the index number.

8.3.2Parameterization 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).

Drive operational states are described by parameter r000 whereas fault and alarm messages are described in the power module operating instructions in Section 10.

1.To enter 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 enter the parameter index levels (for indexed parameters) from the parameter number level, press P again 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 again and the parameter value will be displayed.

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 key code is set with P051 = 40.

−The converter is in the correct operational state. Some parameters are “off-line” and cannot be changed when the converter is in the “Run” or on-line state.

−The values of display parameters can not be changed (read only).
