J09 Display of error history
Initial value: Non
Because the latest error data (protection function operation content) are
memorized up to three, the memorized content can be displayed with UP
key and DOWN key. The content of an error that actually occurs at
maintenance etc. can be confirmed afterwards. Because data is
automatically overwritten, data cannot be changed or cleared by
operation.
J10 Return to initial value
(All clear)
Initial value: 0
Unchangeable during driving
When data is set to 1, it rewrites all data and frequency of the function
into the initial values at shipping from NTN. It is used when resetting from
the beginning or clearing data content for return from error. All the values
are substituted into the initial values, therefore record the present values
first. The data change can be effected only by pressing STOP key and Up
key or DOWN key simultaneously because of the operational error
prevention. It automatically returns to a normal mode after rewriting the
data. Therefore leave the external control signal in the state of "Stop."
J11 Change of carrier frequency
Initial value: 0
Unchangeable during driving
(Function installed only in
ECH45)
This changes carrier frequency to control the output. When it was driven
at initial value of 0 (carrier frequency 20kHz) and indication from the
measuring device outputs error due to noise etc., please try to change
setting. Output method of high-frequency noise changes and the
influence may be decreased. If it was judged to be usable, please drive
changing the carrier frequency.
0: 20kHz
1: 14kHz
2: 10kHz
[Note]
① When carrier frequency is set to other than 0 (Initial value), variable
range of driving frequency becomes narrow to 30.0~200.0Hz.
② When carrier frequency is set to other than 0 (Initial value),
modulation frequency becomes audible range and noise (high
frequency sound) generates from the part feeder. When there are
workers around, there may be a case that it is unusable.
J12 Selection of terminal EM function
Initial value: 0
Unchangeable during driving
Signal output to terminal EM is selected.
0: In case protection function works, contact point “Close” signal
outputs between terminals EM-C2.
1: In case protection function works, contact point “Open” signal outputs
between terminals EM-C2
2: Selection is not possible
3: Selection is not possible
4: In-operation signal interlocking to driving of parts feeder outputs on
terminal EM-C2.
(Becomes the same behavior as terminal board
Y1A-Y1C)
5: When driving preparation completes (case that the external control (0
or 1) is selected with function J02 under the condition that protection
function is not working), contact point “Close” signal outputs between
terminals EM-C2.
