■ Problems in PRGM Mode Operation
Symptom Probable cause Corrective action
Some angle display values
are skipped.
A 256 resolution/rotation
(360° notation display)
encoder is used.
Since the encoder angle is converted to 360° nota-
tion to display, some angle values are not dis-
played.
Refer to "Appendix E Angle Data Table (256 Reso-
lution)"
Nothing appears in the bank
number display area.
The bank function is disabled
(16-/32-output models).
Enable the bank function using the F7 menu (bank
enable/disable) in the function setting mode.
Refer to "4.8.5 Enabling the Bank (F7)"
An 8-output model is used. The bank function is available only with 16-/32-out-
put models and is not provided on an 8-output
model.
There is no response when
the CAM, STEP, or ANGLE
key is pressed.
The bank number display is
flashing because a bank has
not been selected.
(16-/32-output models)
No key operation is accepted while a bank is not
identified. Select a bank by pressing the [WRITE]
key.
Refer to "4.8.3 Designating the Bank Using the
Keys"
The step number does not
increase above a certain
value even when the STEP
key is pressed.
The step number limit func-
tion has been set.
The step number limit function is enabled to pre-
vent setting errors.
To change the set limit on the number of steps, use
the F5 menu (step number limit) in the function
setting mode.
Refer to "4.6 Step Number Limit (F5)"
Some cams are not dis-
played when the CAM key is
pressed.
Cam protection is set. The cam protection function is enabled to stop dis-
playing specific cams in order to prevent setting
errors.
To change the setting for the cam protection func-
tion, use the F6 menu (cam protect) in the function
setting mode.
Refer to "4.7 Cam Protection (F6)"
Settings are not cleared
although the [CLEAR] key is
pressed.
The [WRITE] key has not
been pressed.
Even if the [CLEAR] key is pressed, clear process-
ing is not executed unless the [WRITE] key is
pressed. Pressing the [CLEAR] key simply causes
the H8PS Cam Positioner to enter the clear mode.
Refer to "3.8 Clearing the Settings"
Moving to the ADV function
setting screen is not possible.
The cam display does not
show a number in the range
No. 1 to No. 7.
ADV function setting is allowed for cam No. 1 to
No. 7. Setting is not possible for other cam num-
bers.
Set the ADV function for cam No. 1 to No. 7.
Refer to "4.2.2 Specifications of Advance Angle
Compensation Function Setting"
The cam number does not
increase to No. 8 or a higher
number when the CAM key
is pressed on the ADV func-
tion setting screen.
"ful" appears in Main dis-
play for one second in
response to the pressing of
the [WRITE] key.
(during programming for a
cam with a 32-point model)
An attempt was made to
write a program that will
exceed the maximum num-
ber of steps, which is 160.
Although up to 10 steps can be programmed for
each cam, the total number of steps for all cams
must not exceed 160. Take appropriate measures
to ensure that the programmed number of steps
does not exceed 160, such as enabling the pulse
output function (refer to "4.4 Pulse Output (F1/
F2)").
The E24 error message does
not appear although an
encoder is disconnected.
The present mode setting is
PRGM/MAN.
In the PRGM/MAN mode setting, programming is
allowed without connecting an encoder.
The E24 detection function is
disabled.
Enable the function using the F10 menu (E24
detection enable/disable) in the function setting
mode.
Refer to "4.9 E24 Detection Enable/Disable (F10)"
