2. Basics of parameter setting
The drive can be adapted to your specific applications by
parameter setting of the axis modules. The possible settings are
arranged in the form of codes, which are numbered in ascending
order and start with the letter "C". Each code provides several
parameters which can be selected according to the application.
Parameters can be direct values of a physical unit (e.g. 50Hz or
50% related to f
dmax
) or numerical codes giving certain status
information (e.g. -0- = controller inhibited, -1- = controller enabled).
In cases where the parameters represent values of physical units, it
is possible to vary the increment.
Example: The acceleration and deceleration can be set in
increments of 0.01 s up to 1 s and in increments of 0.1 s from 1 s
upwards.
For codes with more than 5 digit values, the keypad operation is
different: In the parameter level, the cursor can be shifted to enter
large values. This is done by pressing SH+
▲ and SH+ ▼ (see
example on page 44).
In some codes, parameters can only be read but not changed.
In the factory setting, only those codes are displayed which are
necessary for the most common applications. For activation of the
extended code set see code table C 000.
2.1. Change parameters
Each code has a factory set parameter which can be changed.
There are three different ways of selecting and confirming a new
parameter, depending on the code:
Direct acceptance
The servo axis immediately accepts the new parameter, i.e. while
you change it using the
▲ or ▼ -key. This is possible even when the
drive is running. Parameters which are immediately accepted are
marked with ON-LINE in the code table.
Acceptance with SH + PRG
The axis accepts a new parameter when SH + PRG are pressed.
This is possible even with the drive running. First press SH and
then in addition PRG. The display shows --ok-- for 0.5 seconds.
The axis module now works with the new parameter. The key
combination SH and PRG can be compared to the "return" key on
your computer keyboard. If you have to set a parameter of a code
in this way, the code table shows the symbol SH + PRG.
