6. Menu Parameters
6.1 Introduction
This section describes the use of parameters. The next two
chapters describe the Fieldbus Coupler menu parameters in detail.
6.2 Parameter
Attributes
Each parameter has a number of attributes, which define the
security classification, how the value is used and how the drive acts
when a value is changed. The attributes for each parameter are
given in the parameter list at the end of the relevant section.
The parameter attributes are as follows:
R = Read Only, these are either set during manufacture or are
parameters that are used to monitor the state of various functions of
the drive while it is running.
E = Engineer Accessible, these are drive configuration parameters
which are set as part of the system design or during commissioning,
and which should not be changed during normal operation. Refer
to the drive manual for information on access control.
O = Operator Accessible, these are parameters which are used to
control the drive within normal operating limits, and may need to be
changed during normal operation. Refer to the drive manual for
information on access control.
L = List Parameter, when stepping through the parameter values
using the keypad up and down arrow buttons, the values are
chosen from a pre-set list, and no intermediate values are available.
N = Enter Parameter, some parameters may cause undesirable
results if intermediate values are passed to the drive immediately
while stepping through the values. To activate a changed
parameter value with an N attribute press the keypad ENTER
button after selecting the correct value.
S = Stop To Edit, the drive must be stopped before this parameter
can be updated.
