■ Problems during Preparatory Steps/Initial Setting
Symptom Probable cause Corrective action
None of indicators is lit. Power is not supplied cor-
rectly.
Check if the power cables are connected to the
power supply terminals correctly and also if the
power supply voltage is correct.
After turning the power on,
all indicators are lit for too a
long time.
Power on operation immedi-
ately after changing the DIP
switch setting (changing the
encoder resolution setting)
In this case, the processing time is longer (by
approx. 3 seconds) than for normal processing.
In normal processing, i.e., when the DIP switch
setting has not been changed, the H8PS Cam
Positioner starts running after approximately one
second.
The display angle does not
match the actual angle of the
encoder.
The DIP switch resolution
setting does not match the
resolution of the encoder.
Correct the DIP switch setting (encoder resolution)
to match the encoder to be connected.
Refer to "3.3.1 Selecting the Encoder Resolution"
An E2
error suddenly
occurs although the encoder
is rotating at a low speed.
Although the DIP switch set-
ting has been changed, the
new setting is not effective.
The power has not been
cycled.
The H8PS Cam Positioner reads the DIP switch
setting when the power is turned on. To make the
new setting effective, cycle the power.
Refer to "3.3 DIP Switch Setting"
The movement is not smooth
although the encoder has
been replaced with another
with the same resolution
The origin has shifted. When the encoder is replaced, the origin must be
set again.
Refer to "3.4 Setting the Origin"
The angle decreases. (The
rotation display monitor turns
counterclockwise.)
The direction of rotation set-
ting is incorrect.
Set the direction of rotation correctly with the DIP
switch.
Refer to "3.3.2 Setting the Rotation Direction"
Switching to the function set-
ting mode is not possible.
The programming mode is
not selected.
After setting the mode switch to PRGM, hold the
[ADV] key down for at least three seconds.
The bank number display is
flashing (16-/32-output mod-
els only).
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 [ADV] key is not held
down long enough.
Hold the [ADV] key down for at least three sec-
onds, until "F1" appears in Main display.
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)"
