Problem
Cause
Solution
Product cannot be
operated with PLC.
Mode is set to TOOL mode.
Change the mode to the PLC mode using the setting software
(S-Tools).
Wiring is not correct.
Refer to Chapter 4 in "Controller Instruction Manual (SM-A10615)"
and check the wiring.
Wiring is disconnected.
Check for pinching and disconnection of cables and check the
connection of connectors and terminals.
Overload error occurs.
Check the transfer load and the speed.
Power capacity is insufficient.
Check that the power capacity satisfies the required voltage and
current.
Workpiece moves
due to its own weight
during an emergency
stop.
Load exceeding holding force is
applied.
Check whether an external force greater than the holding force is
applied.
Check the setting of the "Current during stop" in the parameter
data.
Positioning
completion output
does not turn off.
Positioning completion output
width is too large compared to
travel distance.
Check the "Positioning width" in the point data.
Pressing operation
cannot be performed.
(Mode is) not set to pressing
operation.
Check the "Operation method" in the point data.
Device is out of step.
Load or speed has exceeded
limit.
Check that the workpiece weight and the operation speed satisfy
the specified values.
Product cannot
achieve desired
speed (it is very
slow).
It is set to pressing operation
instead of general transfer
movement.
Check the "Operation method" in the point data.
Perform a gain adjustment.
Overshoot occurs.
Both transfer weight and amount
of deceleration are large.
Check that the workpiece weight and the operation speed satisfy
the specified values.
Perform a gain adjustment.
Product cannot reach
target takt time.
Setting of acceleration or speed
is not correct.
Check the "Acceleration" and the "Speed" in the point data.
If you have any other questions or concerns, contact your nearest CKD sales office or distributor.
