®
/ Specific Product Precautions
5. 1 Design / Selection
(1) Make sure that you have read and understood this operation manual for the Card Motor and
the one for the LATC4 series controller.
Handling, usage or operation other than that specified in the operation manuals may lead to
breakage, malfunction and operation failure of the product. Any damage caused by usage out of the
specifications and descriptions in the operation manuals is not guaranteed.
(2) If a change in the force of friction in the Card Motor due to stress between the sliding surfaces
or a change in the load weight, jerking motion at a speed exceeding the set speed may occur
caused by stick-slip.
In such cases, human injury may occur; e.g., fiingers hands or feet caught in the machinery, or
damage to the machinery itself may occur. Therefore, the machine should be designed to operate
smoothly and to avoid such dangers.
(3) A protective cover is recommended to minimize the risk of personal injury.
If there is a possibility that a driven object or moving parts of the Card Motor may lead to personal
injury, mount a protective cover to prevent direct physical contact.
(4) Tighten securely all stationary parts and parts mounted to the Card Motor so that they will not
come loose.
When the Card Motor operates with high frequency or is installed where there is a lot of vibration,
ensure that all parts remain secure.
(5) Consider the possibility of power source related malfunctions.
Take measures to prevent human injury and damage to the equipment in the case of a power source
failure.
(6) Consider possible movements of the actuator in the event of an emergency stop, an alarm or
power failure.
If power is not supplied to the product due to an emergency stop, if the SVON signal is switched OFF,
in the event of an alarm (when the temperature of the Card Motor exceeds 70
o
C) or at power failure,
the table will not be held in place and may be moved by external forces. Design the Card Motor
application so that people and equipment will not be injured or damaged by the table movement.
(7) Consider the operation conditions when the operation is restarted after an emergency stop or
abnormal stop.
Design the machinery so that it cannot cause injury or equipment damage when restarting the
operation.
(8) Do not disassemble the product or make any modifications to it.
Do not modify or alter the product (including any additional machining of the product). It may cause
accidents and/or injury.
(9) When using it in vertical orientation, it is necessary to build in a safety device.
Install safety equipment, which prevent human injury or damage to the equipment if the load drops.
