Trouble type
Is it possible to count the pulses
when the B phase is set to "1", and
only A phase pulses are input?
Can a manual pulse generator
Manual pulse
other than the Mitsubishi MR-
generator operation
HDP01 be used?
Can one manual pulse generator
be operated connected to several
AD75 modules?
The BUSY signal is not canceled
Current value change by the current value change. How
can it be canceled?
The AD75 READY signal does not
AD75 READY signal turn OFF even when the PLC
READY signal [Y1D] is turned ON.
Is there any problem with setting
an M code ON signal OFF request

in the next scan after the M code

Must an in-position signal always

be wired?
How long is the output time for the
deviation counter clear signal?
Is a deviation counter clear signal

complete?
How can a deviation counter clear
signal be output?
Where is the current version of the
AD75 written?
Is it possible that the delivered
module is a different version than
the version delivered 1 year ago?

Questions/Trouble
Not possible.
(The AD75 counts 1, 0, 1, 0.)
Other manual pulse generators can be used if they
conform to section "3.5 Specifications of input/output
interfaces with external devices."
This is possible if the system conforms to the electrical
specifications.
The BUSY signal may remain if the scan time is long.
Use a complete signal to check whether the new value
has been executed.
"A parameter error" has occurred.
Confirm the error No. in the error history, and correct the
parameter.
The AD75 checks the M code ON signal OFF request
every "56.8ms", so there is a possibility that the M code
ON signal OFF may be delayed by a maximum of
"56.8ms" after the M code ON signal ON, even if an M
code ON signal OFF request is set.
The in-position signal is not particularly used in the AD75
processing, so it does not always have to be wired.
(In the AD75, the input in-position signal is only output in
the monitor area.)
"10ms".
A signal is not output.
The only time the AD75 outputs a deviation counter clear
signal is for a machine zero point return.
The AD75 does not output a deviation counter clear signal
except for machine zero point returns.
The version is shown on the label on the front of the
module. (Refer to section "4.1.2 Names of each part".)
That is possible.
The parameters in the module may differ.
Check if the AD75 READY signal [X0] turns OFF when
the PLC READY signal [Y1D] turns ON.
When the PLC READY signal is ON but the AD75 READY
signal is ON, the parameter error has occurred. Check the
error code and modify the parameter with the error.
The parameter settings on the AD75 side may not match
those on the servo side.
Check the parameter settings.
The speed shown on the AD75 monitor is calculated from
the No. of pulses output from the module. Thus, the actual
motor speed cannot be monitored.
(" Md.31 Feedrate" monitors the commanded speed. It
does not show the actual speed.)
No.
If the transfer is carried out normally, "0" will be stored in
buffer memory "5103".
If the transfer ended abnormally, a warning will be stored
in the " Md.34 Axis warning No".
