Chapter 6 - Parameter Description [I/O]
6-42
Note: When setting P Pulse Input Min/Max Freq.
via motor encoder, set the value for encoder pulse
per the following example:
To give 60Hz (1800 rpm) command from 1000 Pulse
encoder:
I/O-15 [Max Freq of P Pulse Input] =
Rated rpm/60 sec * Number of Encoder Pulse =
1800 [rpm]/60[sec] * 1000 = 30000 Hz,
Therefore, set I/O-15 to 30 KHz
I/O-17, 18, 19: Criteria for Analog Input Signal Loss
I/O-17 sets the criteria for losing the analog input
signal when DRV-04 [Frequency Mode] is set to ‘V1’,
‘V1S’ ‘I’, or ‘Pulse’. This function does not operate
when DRV-04 is set to V1 + I.
The following table describes the settings in I/O-17.

Setting Range
Description
None Disabled.
half of x1
The drive determines that the
frequency reference is lost when the
analog input signal is less than half of
the minimum set value (I/O-02, I/O-07
or I/O-13).
below x1
The drive determines that the
frequency reference is lost when the
analog input signal is less than the
minimum set value (I/O-02, I/O-07 or
I/O-13).
I/O-18 [Operating method after loss of analog freq.
command] selects the action the drive will take after
losing the analog signal.
The following table describes the settings in I/O-18.

Description
None Continuous operation.
FreeRun
The driver shuts down by coasting to
a stop.
Stop
The drive stops using its Decel
pattern and Decel time.
Protection
The drive trips and displays Lost
Cmd fault.
When the analog input signal is lost, the drive will
display one of the following messages, as shown in the
table below.

I/O-19 [Time out] sets the delay time after the signal is
lost before the drive determines loss of signal.
