Frequency Hold
Applications
General application
Auto Restart after Fault
Applications
Air conditioners,
remote pumps
Emergency Stop by DC Braking
Applications
High-speed rotors
Over-torque Setting
Applications
Pumps, fans and
extruders
Upper/Lower Limit Frequency
Applications
Pump and fan
4-16
Purpose
Acceleration/
deceleration pause
Purpose
For continuous and
reliable operation
without operator
intervention
Purpose
Emergency stop
without brake
resistor
Purpose
To protect
machines and to
have continuous/
reliable operation
Purpose
Control the motor
speed within
upper/lower limit
Functions
Hold output frequency during
Acceleration/deceleration
Functions
The AC motor drive can be
restarted/reset automatically up to 10
times after a fault occurs.
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.
Functions
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.
Functions
When user cannot provide
upper/lower limit, gain or bias from
external signal, it can be set
individually in AC motor drive.
