Keep Running when Frequency Command is Lost
Applications Purpose Functions
Related
Parameters
Air conditioners For continuous operation
When the frequency command is lost
because of a system malfunction, the AC
motor drive still runs. Suitable for
intelligent air conditioners.

Output Signal during Running
Applications Purpose Functions
Related
Parameters
General application;
mechanical brake
Provide a signal for
running status
Signal available to stop braking (brake
release) when the AC motor drive is
running. (This signal disappears when
the AC motor drive is free-running.)
03.00
Output Signal in Zero Speed
Applications Purpose Functions
Related
Parameters
General application;
machine tools
Provide a signal for
running status
When the drive’s output frequency is
lower than the minimum output
frequency, gives a signal for an external
system or control wiring.
03.00
Output Signal at Set Frequency
Applications Purpose Functions
Related
Parameters
General application;
machine tools
Provide a signal for
running status
When the drive’s output frequency
reaches the set frequency (from the
frequency command), gives a signal for
an external system or control wiring
(frequency reached).
03.00
Output Signal at Over-torque
Applications Purpose Functions
Related
Parameters
Machine tools, fans,
pumps, and extruders
To protect machines and
for reliable operation
When the motor over-torque is larger
than the drive's setting level, gives a
signal to prevent the machine from
damage due to load.

Output Signal at Low Voltage
Applications Purpose Functions
Related
Parameters
General application
Provide a signal for
running status
When low voltage is detected after the
motor detects the P-N voltages, gives a
signal for an external system or control
wiring.
03.00
Output Signal at Desired Frequency
Applications Purpose Functions

Parameters
General application
Provide a signal for
running status
When the drive’s output frequency
reaches the desired frequency, gives a
signal for an external system or control
wiring.
