Chapter 4 - Parameter Description [I/O]

[Analog Hold]
When there is an analog input signal for
frequency reference and ‘Analog hold’ terminal is
ON, inverter fixes its output frequency regardless
of the frequency reference change. The changed
frequency reference is applied when the terminal
is OFF.
This function is useful when a system requires
constant speed after acceleration.
[Analog Hold Operation]
I/O-15: Terminal Input Status
I/O-16: Terminal Output Status
This code displays the input status of control
terminals.
This code displays the output status of control
terminals.
I/O-17: Filtering Time Constant for Multi-function
Input Terminals
This is the response time constant for terminal
inputs (JOG, FX, RX, P3, P2, P1, RST, BX). This
is useful where there is a potential for noise. The
response time is determined by ‘Filtering time
constant * 0.5msec’.
I/O-20: Jog Frequency
This code sets the jog frequency. See [Speed-L,
Speed-M, Speed-H] in I/O-12 ~ I/O-14.
Jog terminal has priority over any other input
terminal in action.
I/O-21 ~ I/O-24: Step Frequency 4, 5, 6, 7
