100% braking torque at 20% duty cycle.
Resistor assemblies listed are manufactured by IPC Power Resistors
Int’l, Inc. and have been tested with the 1336 SPIDER Drive.
Equivalent resistor packages may be used if they conform to the
ratings shown.
Available resistor assembly options include an overtemperature
switch, auxiliary terminal blocks and custom enclosures.

ATTENTION: The drive does not offer protection for
externally mounted brake resistors. A risk of fire exists if
external braking resistors are not protected. External
resistor packages must be self-protected from over
temperature or the protective circuit (or equivalent) shown
on page B–4 must be supplied.
