SD710 Series Servo Drive User Manual Chapter 1 Safety Precautions
5
1.6 Precautions During Operation
Attention
⚫
During trial operation, to prevent accidents, test run the servo motor with no load (state not connected to the
drive shaft), otherwise injury may result.
⚫
Never touch the rotating part of the servo motor while it is running, as this may cause injury.
⚫
When installing the servomotor on an ancillary machine and starting operation, set the user parameters in
advance to match the machine. If operation is started without parameter setting, the machine may go out of control or
malfunction.
⚫
The signals of positive limit (P-OT) and negative limit (N-OT) are invalid when home return is performed.
⚫
When using a servo motor in the vertical axis, set a safety device to prevent the workpiece from falling in case
of alarm or overtravel. Also, set the servo lock stop when overtravel occurs, otherwise the workpiece may fall in the
overtravel condition.
⚫
When not using online auto-tuning, be sure to set the correct inertia ratio, otherwise vibration may be caused.
⚫
When the power is on or just after the power is cut off, the heat sink of the servo driver, external braking
resistor, motor, etc. are in a high temperature state, so please do not touch them or they may cause burns.
⚫
Since extreme user parameter adjustments and setting changes can cause the servo system to become
unstable in operation, do not set extreme parameters, as this may cause injury.
⚫
When an alarm occurs, please reset and restart operation after removing the cause and ensuring safety,
otherwise it may cause injury.
⚫
Do not use the holding brake of the holding motor for normal braking, as this may lead to malfunction.
1.7 Precautions for maintenance and inspection
Attention
⚫
The operation of turning on and off the power supply should be carried out by professional operators.
⚫
When performing the insulation resistance test of the drive, please disconnect all circuits connected to the drive
first, otherwise it may cause the drive to malfunction.
⚫
Do not use gasoline, thinner, alcohol, acidic and alkaline detergent to avoid discoloration or breakage of the
housing.
⚫
When replacing the servo drive, please transfer the user parameters of the servo drive to be replaced to the
new servo drive before restarting operation, otherwise the machine may be damaged.
⚫
Do not change the wiring while the power is on, as this may cause electric shock.
⚫
Do not disassemble the Servo Motor as this may result in electric shock or injury.
