General Warnings and Safety Precautions
3
!WARNING
Do not touch the rotating parts of the Servomotor in operation. Doing so may result in
injury.
!WARNING
Do not modify the product. Doing so may result in injury or damage to the product.
!WARNING
Provide safety measures in external control circuits (i.e., not in the MC Unit) to ensure
safety in the system if an abnormality occurs due to malfunction of the MC Unit, incorrect
or unintended configuration and programming of the MC Unit or external factors affecting
the operation of the MC Unit. Not providing sufficient safety measures may result in seri-
ous accidents, or property damage.
• The MC Unit outputs may remain ON or OFF due to deposits on or burning of the out-
put relays, or destruction of the output transistors. As a counter-measure for such prob-
lems, external safety measures must be provided to ensure safety in the system.
• Provide an external emergency stopping device that allows an instantaneous stop of
operation and power interruption. Not doing so may result in injury.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures
must be provided in external control circuits.
• When the 24-VDC output (service power supply to the Unit) is overloaded or short-cir-
cuited, the voltage may drop and result in the outputs being turned OFF. As a counter-
measure for such problems, external safety measures must be provided to ensure
safety in the system.
!WARNING
It is the nature of high speed motion control and motion control language programming
and multi-tasking systems, that it is not always possible for the system to validate the
inputs to the functions or to validate the combination of functions.
!WARNING
It is the responsibility of the programmer to ensure that the various BASIC statements are
invoked correctly with the correct number of parameters and inputs, that the values are
correctly validated prior to the actual calling of the functions, and that the BASIC pro-
gram(s) provide the desired functionality for the application. Failure to do so may result in
unexpected behaviour, loss or damage to the machinery.
!Caution
When the SERVO_PERIOD parameter has been set to change the servo cycle period of
the MC Unit, a power down or software reset (using DRV_RESET) must be performed for
the complete system. Not doing so may result in undefined behaviour.
!Caution
Use the Servomotors and Servo Drivers in a specified combination. Using them incor-
rectly may result in fire or damage to the product.
!Caution
Do not operate the control system in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified in the speci-
fications.
• Locations subject to condensation due to radical temperature changes.
• Locations subject to corrosive or inflammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to vibration or shock.
• Locations subject to exposure to water, oil or chemicals.
!Caution
Do not touch the Servo Driver radiator, Regeneration Resistor, or Servomotor while the
power is being supplied or soon after power is turned OFF. Doing so may result in a skin
burn due to the hot surface.
