(Note) In "Frequency matching start," operation starts at motor coasting
speed to reduce the chance of tripping. However, response is
slower than "Restart from 0 Hz."

function setting
• Functions are selected and assigned freely to input
terminals, FR through RST. – permits
selection of input signal polarity A-contact (NO) or B-
contact (NC) for each terminal.
• and are only for HF-320.

• Forward/reverse operation command
Use this when operating the inverter with an external contact
signal. (control terminal)
It is valid when the operation command destination is
"Terminal block."

• Multi-stage speed command (Refer to p.7.)
• Inching operation command (Refer to p.7.)
• No.2 acceleration/deceleration command
The No.2 acceleration/deceleration change method
must be set to "terminal" by . (Refer to p.9.)
• Free-run stop command
The inverter output can be cut off during operation for
free-run stop of the motor. It can be used on a motor
with brake.
•
External trip input
Use this to shut off inverter output with external contact
signal to provide safety interlock with operating
equipment.
(Note) External trip input is assigned to the inputs (FR through RST).
When this function is activated, the inverter outputs an fault signal
and cuts off output.
• USP (Urattended Start Prevention) function
The function can prevent resumption of operation when the
power retarns with operation command engaged. When this
function is enabled and power is applied with run (operation)
command issued to the control terminal, the drive trips and
displays the trip code for "USP error."
• Software lock (Refer to p.10.)
• Analog current input selection
Analog input for frequency command can be switched
between voltage (0-10VDC) and current (4-20mA) inputs.
When using analog current input or analog voltage input, set
the frequency command destination to "Terminal."
