Operation
• Always use the linear servomotor and SERVOPACK in one of the specified combinations.
Failure to observe this caution may result in fire or malfunction.
• Do not stand within the machine's range of motion during operation.
Failure to observe this caution may result in injury.
• Before operation, install a limit switch or stopper on the end of movable range to prevent unex-
pected movement.
Failure to observe this caution may result in injury.
• During trial operation, confirm that the holding brake works correctly. Furthermore, secure system
safety against problems such as signal line disconnection.
• Before starting operation with a machine connected, change the settings to match the parameters
of the machine.
Starting operation without matching the proper settings may cause the machine to run out of control or mal-
function.
• Do not frequently turn power ON and OFF.
Since the SERVOPACK has a capacitor in the power supply, a high charging current flows when power is
turned ON. Frequently turning power ON and OFF causes main power devices like capacitors and fuses to
deteriorate, resulting in unexpected problems.
• When using JOG operations (Fn002), search operations (Fn003), or EasyFFT operations (Fn206),
forcing movable machine parts to stop does not work for forward overtravel or reverse overtravel.
Take necessary precautions.
Failure to observe this caution may result in damage to the product.
• When using the linear servomotor on a vertical axis, install a safety device such as a counterbal-
ance so that the workpiece does not fall if an alarm or overtravel occurs. And, set the parameters so
that the linear servomotor will stop by using a zero clamp at occurrence of overtravel.
The workpiece may fall during overtraveling.
• When not using turning-less function, set to the correct mass ratio (Pn103).
Setting an incorrect mass ratio may cause vibration.
• Do not touch the SERVOPACK heatsinks, regenerative resistor, or linear servomotor while 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.
• If an alarm occurs, shut down the main circuit power supply.
Failure to observe this caution may result in fire due to regenerative resistor overheating caused by regenera-
tive transistor failure.
• When an alarm occurs, remove the cause, reset the alarm after confirming safety, and then resume
operation.
Failure to observe this caution may result in damage to the product, fire, or injury.
• An alarm or warning may be generated if communications are executed with the host controller dur-
ing operation using SigmaWin+ or the digital operator.
If an alarm or warning is generated, the process currently being executed may be aborted and the system may
stop.
Maintenance and Inspection
• Do not disassemble the SERVOPACK or the linear servomotor.
Failure to observe this caution may result in electric shock or injury.
• Do not 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 copying the previous SERVOPACK
parameters to the new SERVOPACK.
Failure to observe this caution may result in damage to the product.
