Gland kits
Gland kits are available for frame sizes B, C and D.
Metal EMC glands are used for motor and brake resistor
cables.

7&.P
SoftCom is an optional software that runs on a personal
computer. It can also be used to load parameter settings
from the AC drive to the PC for backup and printing.
Recording can be made in oscilloscope mode. Please contact

13.5
Brake chopper
All AC drive sizes AC drives with cable inlet on short side
can be fitted with an optional built-in brake chopper. The
brake resistor must be mounted outside the AC drive. 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:

P

EDeffective braking period. Defined as:
t
br
Active braking time at nominal braking
power during a 2 minute operation
cycle.
Maximum value of ED = 1, meaning continuous braking.

WARNING!
The table gives the minimum values of the
brake resistors. Do not use resistors lower
than this value. The AC drive can trip or even
be damaged due to high braking currents.
