7. Main features
This chapter contains descriptions of the main features of
the Emotron TSA softstarter.
7.1 Setting Start, Stop and
Run functions
7.1.1 Start and stop control
The start and stop control signals can be given from the
control panel using the control keys, via remote control (i.e.
programmable I/O), or via serial communication. Valid
motor rotation direction is set in menu [219] (see Fig. 34).
Follow the procedure in Fig. 35 for setting of the start and
stop signals.

For configuration of programmable I/O, see the description
for the respective input/output. For a list of the different
possibilities, see section 7.4, page 61.
Local and remote control mode
An additional possibility for start and stop control is given
with the LOC/REM function of the toggle key (setting
“LOC/REM” in “Function Key” menu [2171]). It is up to
the user to define the “REMOTE” and “LOCAL” functions
in the menus for “Run/Stop Control” [2151] and “Local
Run Control” [2173]. In that respect the LOC/REM key
becomes a tool not just to alternate between the control
panel and I/O control, but actually to quickly change
between any two start and stop control locations. See
description in section 6.5.2, page 47.
7.1.2 Start and stop methods
The methods for starting and stopping the motor are
configured in the menus [330] “Start Setting” and [340]
“Stop Setting”. See descriptions in section 8.3.3, page 91.
It is also possible to apply a “Start Limitation” [234] as part
of the actions used for protecting the motor. The functions
for doing this are mainly related to time settings, e.g.
limiting the numbers of starts per hour or securing a
minimum time delay between starts. For guidelines
regarding specific applications, refer to “The Application
Functions List” on page 33.
If the load monitor function [410] is activated (page 56), it
could be necessary to apply a load monitor start delay time
[417] in order to avoid faulty alarms during start-up due to
the high start current.
Spinbrake
Spinbrake is used to brake a freewheeling application to
standstill, e.g. a fan which is rotating due to wind. Spinbrake
can be selected as a function for a digital input [520], see
section 8.5.2, page 108. Spinbrake can only be activated
when the TSA is non-operational, i.e that Stp is shown in
the display.

NOTE: If you try to give an incorrect command e.g. Run
forward when rotation direction set in menu [219] is set
to Run Reverse, nothing will happen or be indicated.
