Parameter Types
There are two fundamental types of parameters in the drive, read only (R/O) and read/write (R/W). The read only parameters
cannot be changed by the user and are there to give the user useful information about the state of the drive. Read/write
parameters are for the user to set up the way in which the drive operates.
Parameters can be further broken down into Bit parameters and Non-bit parameters. Bit parameters are two state only (0 or
1) and if R/W are used as switches or two state input variables to the drive logic, or if R/O indicate various drive conditions
which are either true (1) or false (0). Non-bit parameters have more than two values the range of each being given in the
following descriptions.
In the basic parameter set, some parameters are represented as strings rather than numeric values which give a more
informative indication of the parameter setting.
Since the parameters in the basic parameter set are copies of extended parameters, in the descriptions below the strings are
indicated as well as the numeric value. Setting up via the serial interface requires numeric data.
Most parameters when being adjusted take immediate effect, but there are some which do not. These are generally
parameters which could cause a malfunction in the operation of the drive if an intermediary value were taken during the
adjustment, such as parameters defining the destination of programmable inputs. For the new value of one of these
parameters to take effect a 'Drive Reset' must be carried out (see below). Parameters which require a 'Drive Reset' before
any new value becomes effective are coded with an R in the following descriptions.
Any changes made to parameters over the serial interface are not stored in the drives EEPROM until a manual store is
initiated.
It will be seen later that Bit parameters can be controlled by programmable logic inputs or internal logic functions, and Non-bit
parameters can be controlled by programmable analog inputs or internal drive functions. However, some parameters are of
such a sensitive nature that they are protected from being controlled by programmable inputs and functions and these are
coded with a P in the following descriptions.
2.1
Drive Reset
A drive reset is required for a number of reasons:
•
To reset the drive from a tripped state
•
To initiate loading of defaults
•
To implement a change in the value of certain parameters
•
To initiate the saving of parameters in EEPROM
The later two of these can be carried out while the drive is running.
The drive can be reset in one of four ways:
•
The drive will be reset with a 0 to 1 transition of the drive enable when the drive is tripped, such that a dedicated reset
terminal is not required.
•
The drive will be reset when a 0 to 1 transition of the Drive Reset parameter (10.33). This parameter is provided for
control by a programmable digital input such that a terminal can be used to reset the drive.
•
The Stop/Reset key. If the drive is not in keypad mode and the 'always stop' parameter is not set, then the key has a drive
reset function only. In keypad mode or if the 'always stop' parameter is set, a drive reset can be carried out while the drive
is running by holding the Run key while the Stop/Reset key is activated. When the drive is not running the Stop/Reset key
will always reset the drive.
•
By the serial interface. This drive reset is triggered by a value of 100 being written to the User trip parameter (10.38).

Storing drive parameters
Using SE Soft:
•
Go to 'Tools' on tool bar
•
Click on 'Save parameters in drive'
•
Click on 'OK drive reset - parameters saved' box when prompted -
OR
•
Go to 'Compare and Menu Tables'
•
Select 'Menu 1' (or any other Menu)
•
Set 01.00 (or xx.00) to 1000 and perform a RESET as above
Using Universal keypad:
Set any Menu zero parameter, parameter xx.00 to 1000 and perform a RESET as above or:
•
Press the red STOP/RESET key on the Universal keypad (if enabled)
