13. Options
The standard options available are described here
briefly. Some of the options have their own instruction
or installation manual. For more information please
contact your supplier.
13.1 Options for the control
panel
Mounting cassette, blank panel and straight RS232-
cable are available as options for the control panel.
These options may be useful, for example after mount-
ing a control panel in a cabinet door.

13.2 EmoSoftCom
EmoSoftCom is an optional software that runs on a per-
sonal computer. It can also be used to load parameter
settings from the VSD to the PC for backup and printing.
Recording can be made in oscilloscope mode. Please
contact TECO sales for further information.
13.3 Brake chopper
All VSD sizes can be fitted with an optional built-in
brake chopper. The brake resistor must be mounted
outside the VSD. The choice of the resistor depends on
the application switch-on duration and duty-cycle. This
option can not be after mounted.
The following formula can be used to define the power
of the connected brake resistor:

01-3957-01 Panel kit complete including blank panel
WARNING: The table gives the minimum
values of the brake resistors. Do not use
resistors lower than this value. The VSD can
trip or even be damaged due to high braking
currents.
