Precautions on Use
2-3
Mounting and Installation
●
Do not attempt to apply external force on the linear scale, encoder holder or encoder head.
●
Design the assembly with the scale not to have anything that could give influence partially to
the magnetic field such as metal positioning pins.
●
Avoid any use in an environment with strong external magnetic field such as a place near a
magnet.
It may cause a reading error of an encoder or damage on this product.
Consult with our IOT Innovation Division in case of use in an environment with external
magnetic field.
●
Perform wiring properly following this manual (7-1 Wiring).
●
The users are required to evaluate the performance, safety and EMC by them selves when an
extension cable other than our standard types is used. Shielded cable is recommended in
such kind of modification.
●
Use protection gears before start working.
●
Make sure there is nobody around you when you transfer a product with long dimension.
●
As a countermeasure for noise from the power supply cable, separate the power supply
cable from the cables on this product for wiring.
●
Thoroughly remove anti-rust oil and feed lubricant before using the product.
2-4
Operation
●
Do not operate the product when there is someone in the operation range or in a dangerous
area.
●
Do not operate the product in a range that exceeds the effective stroke. There is a concern that
the encoder position data cannot be read. Especially when the product is used as the feedback
control, the equipment may go out of control, which could cause critical damage, if operation is
made in a range that exceeds the effective stroke.
* See this manual (10-2 Effective Stroke) for the effective stroke.
●
Ensure safety by means of installation of an appropriate mechanical stopper.
●
Use a device applied with noise countermeasure for the power supply device.
●
Use a higher-level device equipped with power storage feature for a countermeasure of
power flicker.
●
Set up parameters such as resolution properly.
Especially when the product is used as the feedback control, the equipment may go out of
control, which could cause critical damage, if setting of resolution is wrong.
* See this manual (10-1 Resolution Check) for how to check the resolution.
●
In order to avoid any serious accident in the first operation due to such as wrong wiring, set
up the torque of the power source low, speed slow and stroke small.
