Software reset
Software reset is a function to reset the internal status of the servo amplifier and obtain the same effect as cycling the power.
By performing the software reset, the setting of the servo parameters can be reflected without cycling the power.
• In the case of an alarm caused by hardware failure, thermal protection or other factors, the alarm may not
be canceled even if the software reset is performed.
• When MR Configurator2 is connected to the servo amplifier via a network, reconnection may not be
possible if the software reset is performed after changing the setting of the network.
• When using servo motors with functional safety, executing software reset may trigger [AL. 016 Encoder
initial communication error 1]. If [AL. 016] occurs, cycle the power.
Precautions
• Canceling alarms is not the main purpose of the software reset function. Use of this function is not recommended for alarms
that would ordinarily be canceled by cycling the power.
• Perform the software reset while the servo motor is stopped.
Software reset in MR Configurator2
The servo amplifier can be reset with the software reset button in MR Configurator2.
Software reset via network communication [G]
A software reset can be performed by using the remote reset of the controller. For details, refer to the following manual.

Software reset with an object [G]
Available on servo amplifiers with firmware version C4 or later.
Writing "1EA5h" in [Software reset (Obj. 2D5Fh: 00h)] performs the software reset. If a value other than "1EA5h" is written, an
error will be returned.
