Auto Restart after Fault
Applications Purpose Functions
Related
Parameters
Air conditioners, remote
pumps
For continuous and
reliable operation
without operator
intervention
The AC motor drive can be restarted/reset

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

Over-torque Setting
Applications Purpose Functions
Related
Parameters
Pumps, fans and
extruders
To protect machines
and to have
continuous/ reliable
operation
The over-torque detection level can be set.
Once OC stall, OV stall and over-torque
occurs, the output frequency will be
adjusted automatically. It is suitable for
machines like fans and pumps that require
continuous operation.
06-00~06-05
Upper/Lower Limit Frequency
Applications Purpose Functions
Related
Parameters
Pump and fan
Control the motor
speed within
upper/lower limit
When user cannot provide upper/lower
limit, gain or bias from external signal, it
can be set individually in AC motor drive.
