I/O-29: Multi-function input terminal filter time
constant
Debounces and sets the responsiveness of input
terminals M1-M8. Increasing the filter time is effective
when noise level is high. Increasing this parameter will
make response time slower and decreasing it will make
response faster.
Note: Set the parameter higher than 100msec when
attempting Inverter-Commercial Line Exchange
operation. This will prevent chattering during the
transition.
I/O-30: Jog Frequency
This parameter sets the jog frequency.
I/O-31~42: Step Frequency 4, 5, 6, 7, 8, 9, 10, 11, 12,

[Speed-L, Speed-M, Speed-H, Speed-X]
By setting M1, M2, M3 terminals to ‘Speed-L’,
‘Speed-M’ and ‘Speed-H’ respectively, the drive can
operate at seven preset frequencies set in DRV-21 ~
DRV-23 and I/O-31 ~ I/O-34. An additional terminal
M(x) can be set to Speed X to allow eight additional
preset frequencies (total of 15) using parameters I/O-35
~ I/O-42.
The step frequencies are determined by the
combination of M1, M2, M3 and Mx terminals as
shown in the following table.
