This chapter contains descriptions of all the Softstarter
functions and the parameters for configuration.
7.1 Introduction
7.1.1 Setting parameters
Set the parameters via HMI
With the HMI Keypad, you can set parameters for each
item, or as a selection of default parameters for different
applications.
The HMI complete list shows all parameter groups:
01 Motor rated current Ie
02 Start and stop
03 Limit
04 Kick start
05 Slow speed
06 Motor heating
07 Motor braking
7
08 Sequence start
09 Automatic restart
10 Internal IO
11 External IO
12 Communication
13 ... 19 Protections list 1-7
20 ... 24 Warnings list 1-5
25 Internal faults
26 External faults
27 Presentation
28 Service
29 Pump cleaning
For navigation sheets, see chapter 6.4.1 Parameters.
Lock/Unlock parameters
Push and hold the Options -key, Menu-key and
i-key simultaneous for 2 seconds in order to lock
/ unlock the keypad.
This prevents accidental changes of parameters.
Parameters are read-only. Still Start / Stop and
R/L is active.
Set the parameters via Fieldbus/PLC
When Fieldbus is used, you can change parameters from
the PLC.
A different document specification shows more details
about parameter settings changed through Fieldbus/
PLC, see chapter 8

7.1.2 Softstarter states
The Softstarter has multiple operation states, in which
different functions are available.
Functions can operate in one or more Softstarter states.
If a function does not operate in all states, this is noted in
the respective function description.
The Softstarter has these states:
• Individual function
• Stand by
• Pre-start
• Start ramp
• TOR (Top of ramp)
• Stop ramp
Individual function
In Individual function state, the Softstarter runs individual
functions.
Individual functions are:
• Motor heating
• Stand-still brake
• Slow speed forward
• Slow speed reverse
Stand by
In Stand by state the Softstarter runs no functions except
diagnostics.
Pre-start
In Pre-start state the Softstarter runs functions that are
intended to run before the Softstarter goes into Start
ramp state. A pre start function runs during a pre-set
time. Then the Softstarter continues to Start ramp state:
Pre-start functions are:
• Motor heating
• Stand-still brake
• Slow speed forward
• Slow speed reverse
The pre-start functions can also be run as individual
functions.
