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
Revision 10/2005, BE13, SW V4.08
Purpose
Acceleration/
deceleration pause
Purpose
For continuous and
reliable operation
without operator
intervention
Purpose
Emergency stop
without braking
resistor
Purpose
To protect machines
and to have
continuous/ reliable
operation
Purpose
Control the motor
speed within
upper/lower limit
Chapter 5 Parameters VFD-B Series
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 barking for
emergency stop when quick stop is needed
without braking 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.
