Vexta EMP400 Series Operating Manual page 11

General Do not use the controller beyond their specifications, or injury or damage to equipment may
result.
Keep your fingers and objects out of the openings in the controller, or fire may result.
Installation Keep the area around the controller, and data setter free of combustible materials in order to
prevent fire or a burn.
To prevent the risk of damage to equipment, leave nothing around the controller and data setter
that would obstruct ventilation.
Operation Use a controller and driver only in the specified combination. An incorrect combination may
cause a fire.
To avoid injury, remain alert during operation so that the motor can be stopped immediately in an
emergency.
Before switching on the controller, disconnect all of its output signals.
Failure to do so may cause the motor to start unexpectedly, resulting in fire or equipment damage.
Set the speed and acceleration/deceleration rate well within the respective capacities in order to
prevent abrupt load fluctuations.
Failure to do so may cause the motor to misstep and the moving part to move in unexpected
directions, possibly resulting in injury or equipment damage.
When an abnormality is noted, stop the operation immediately, or fire, or injury may occur.
Disposal When disposing of the controller, treat them as ordinary industrial waste.
