MICROMASTER 440 Operating Instructions

The value range, which is specified as a result of the data type, is restricted/limited by
the minimum, maximum value (min, max) and using drive inverter/motor quantities.
Straightforward commissioning (start-up) is guaranteed in so much that the
parameters have a default value. These values (min, def, max) are permanently
saved in the drive inverter and cannot be changed by the user.
No value entered (e.g.: "r parameter")

For MICROMASTER, the units of a particular parameter involve the physical quantity
(e.g. m, s, A). Quantities are measurable properties/characteristics of physical
objects, operations, states and are represented using characters of a formula (e.g. V
= 9 V).

The access level is controlled using parameter P0003. In this case, only those
parameters are visible at the BOP or AOP, where the access level is less than or
equal to the value assigned in parameter P0003. On the other hand, for DriveMonitor
and STARTER, only access levels 0 and 4 are relevant. For example, parameters
with access level 4 cannot be changed if the appropriate access level has not been
set.
The following access levels are implemented in the family of MICROMASTER drive
units:
User-defined parameter list (refer to P0013)
Standard access to the most frequently used parameters
Extended access, e.g. to drive inverter I/O functions
Expert access only for experienced users
Service access only for authorized service/maintenance personnel – with password
protection.
As far as the ability to visualize the parameters is concerned, the group assignment of
the individual parameters must be taken into account. Parameter P0004 is used for
the control (refer to the Grouping).
