Maintenance and Inspection
• Make sure that the motor constants for the spindle motors being used match the parameters of the
SERVOPACKs before supplying power when driving spindle motors by using
Σ
-V-SD series SER-
VOPACK.
Failure to observe this caution may result in injury, fire, and damage to the product.
• When using the servomotor for a vertical axis, install the safety devices to prevent workpieces to fall
off due to occurrence of alarm or overtravel. Set the servomotor so that it will stop in the zero clamp
state at occurrence of overtravel.
Failure to observe this caution may cause workpieces to fall off due to overtravel.
• Do not touch the power regeneration converter and SERVOPACK heat sinks or servomotor while
the power is ON or soon after the power is turned OFF.
Failure to observe this caution may result in burns due to high temperatures.
• Do not make any extreme adjustments or setting changes of parameters.
Failure to observe this caution may result in injury or damage to the product due to unstable operation.
• When an alarm occurs, remove the cause, clear the alarm after confirming safety, and then resume
operation.
Failure to observe this caution may result in damage to the product, fire, or injury.
• Do not use the holding brake on the servomotor for braking.
Failure to observe this caution may result in malfunction.
• The servomotor stopping method of turning the main-circuit or control-circuit power OFF without
turning the servo OFF during operation can not be set in Parameter Pn001.
Refer to
8.4.4 Stopping Servomotor after SV_OFF Command or Alarm Occurrence
for details.
• Do not establish communications with the host controller while running SigmaWin for
Σ
-V-SD (MT),
because an alarm or warning might be issued.
If an alarm or warning is issued, any process currently being executed might be aborted and the system might
also be stopped.
Only when using the following functions, communications with the host controller is allowed while running
SigmaWin for
Σ
-V-SD (MT).
<functions for use with SigmaWin for
Σ
-V-SD (MT) that require communications with the host controller
during use>
• Advanced autotuning by reference
• One-parameter tuning
• Anti-resonance control adjustment function
<functions for use with SigmaWin for
Σ
-V-SD (MT) that will not result in problems if communications estab-
lished with the host controller during use>
• Parameter edit function, excluding parameter initialization
• Monitor function
• Alarm display function, excluding resetting alarms and clearing alarm history
• Data trace function
• Dynamic braking (DB) is an auxiliary function used for emergency stops. It does not guarantee that
the servomotor will come to a full or immediate stop as when a brake is applied. The servomotor
might coast to a stop. Provide appropriate braking devices on the machine side to ensure safety.
• Do not use the servo drive under a load moment of inertia exceeding the maximum allowable value.
Failure to observe this caution may result in damage or malfunction of resistors and power devices in the
SERVOPACK.
CAUTION
• Do not disassemble the power regeneration converter and SERVOPACK.
Failure to observe this caution may result in electric shock or injury.
• Do not attempt to change wiring while the power is ON.
Failure to observe this caution may result in electric shock or injury.
• When replacing the SERVOPACK, resume operation only after transferring the previous SERVO-
PACK parameters to the new SERVOPACK.
Failure to observe this caution may result in damage to the product.
