④
Do not cause a collision at the stroke end, except for return to origin.
The table may collide with the stroke end of the actuator during operation if it is used outside of
the specification range, or if incorrect input instructions are given, such as operation instructions
outside the actual stroke due to changes in the controller/driver settings or origin position. Please
check thoroughly before use. If the table collides with the stroke end, the guide, belt, internal
stopper, etc. may be damaged, resulting in malfunction.
Also, be careful that the work piece may drop when it is vertical.
⑤
Do not change the positioning force from the default setting.
It may cause performance degradation and alarms.
⑥
Do not operate by fixing the table and moving the actuator body.
An excessive load will be applied to the table, which could lead to damage to the actuator and
reduced accuracy and reduced product life.
⑦
Check the specification for the minimum speed of the actuator.
Operation outside the specifications may cause malfunctions such as knocking.
⑧
The actual speed of this actuator is affected by the work load and stroke.
Check the model selection section of the catalog.
⑨
In pushing operation, set the product to a position of at least 2mm away from a work
piece.
(This position is referred to as a pushing start position.)
If the product is set to the same position as a work piece, the following alarm and unstable
operation can occur.
a. "Posn failed" alarm
The product cannot reach a pushing start position due to the deviation of work pieces
in width.
⑩
Do not apply a load or impact or resistance in addition to the operation during a return to
origin.
Otherwise, the origin can be displaced since it is based on the detected motor torque.
⑪
Do not dent, scratch, or cause other damage to the body and table mounting surfaces.
Damage can cause reduction in flatness, play in the guide and an increase in sliding resistance.
⑫
Do not hit the table with the workpiece in the positioning operation and positioning range.
⑬
There is a type where grease is applied to the dust seal band for sliding. When wiping off
the grease remove foreign matter, etc..., be sure to apply grease again.
⑭
For bottom mounting, the dust seal band may be deflected., be sure to apply grease again.
