Vexta aStep AS Series Operating Manual page 5

Maintenance and inspection
• Do not touch the connection terminals of the driver immediately after the power is turned off (for a period of 10
seconds). The residual voltage may cause electric shock.
Repair, disassembly and modification
• Do not disassemble or modify the motor or driver. This may cause electric shock or injury. Refer all such internal
inspections and repairs to the branch or sales office from which you purchased the product.
General
• Do not use the motor and driver beyond their specifications, or electric shock, injury or damage to equipment may
result.
• Keep your fingers and objects out of the openings in the motor and driver, or electric shock, injury or damage to
equipment may result.
• Do not touch the motor or driver during operation or immediately after stopping. The surfaces are hot and may cause
a burn.
Transportation
• Do not hold the motor output shaft or motor cable. This may cause injury.
Installation
• Keep the area around the motor and driver free of combustible materials in order to prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the motor and driver that would obstruct
ventilation.
• Provide a cover over the rotating parts (output shaft) of the motor to prevent injury.
Operation
• Use a motor 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 supplying power to the driver, turn all control inputs to the driver to "OFF." Otherwise, the motor may start
suddenly and cause injury or damage to equipment.
• To prevent bodily injury, do not touch the rotating parts (output shaft) of the motor during operation.
• Before moving the motor directly (as in the case of manual positioning), confirm that the driver C.OFF
(All Windings Off) input is "ON" to prevent injury.
• The motor's surface temperature may exceed 70°C, even under normal operating conditions. If a motor is accessible
during operation, post a warning label shown in the figure in a conspicuous position to prevent the risk of burns.
• When an abnormality is noted, stop the operation immediately, or fire, electric shock or injury may occur.
• To prevent electric shock, use only an insulated screwdriver to adjust the internal switches.
Maintenance and inspection
• To prevent the risk of electric shock, do not touch the terminals while measuring the insulation resistance or
conducting a voltage-resistance test.
Disposal
• When disposing of the motor or driver, treat them as ordinary industrial waste.
