Emergency Stop by DC Braking
Applications
High-speed rotors
Purpose
Emergency stop
without brake
resistor
Functions
AC motor drive can use DC braking
for emergency stop when quick stop is
needed without brake resistor. When
used often, take motor cooling into
consideration.

Over-torque Setting
Applications
Pumps, fans and
extruders
Purpose
To protect
machines and to
have continuous/
reliable operation
Functions
The over-torque detection level can be
set. Once OC stall, OV stall and overtorque occurs, the output frequency
will be adjusted automatically. It is
suitable for machines like fans and
pumps that require continuous
operation.
