The above formulas also apply in reverse movement mode (Pn000 =

If you are using a Linear Servomotor, you do not need to reset the abso-
lute linear encoder to define the origin. (Some absolute linear encoders
also allow you to set any position as the origin.)
7.11 Software Reset
7.11.1 Overview
You can reset the SERVOPACK internally with the software. A software reset is used
when resetting alarms and changing the settings of parameters that normally require
turning the power supply to the SERVOPACK OFF and ON again. This can be used to
change those parameters without turning the power supply to the SERVOPACK OFF and
ON again.
– Always confirm that the servo is OFF and that the Servomotor is
stopped before you start a software reset (the servo cannot be reset
when it is ON).
– This function resets the SERVOPACK independently of the host con-
troller. The SERVOPACK carries out the same processing as when
the power supply is turned ON and outputs the ALM (Servo Alarm)
signal. The status of other output signals may be forcibly changed.
– When you execute a software reset, the SERVOPACK will not
respond for approximately five seconds.
Before you execute a software reset, check the status of the SERVO-
PACK and Servomotor and make sure that no problems will occur.
7.11.2 Preparations
Confirm that the following conditions are met before you perform a software reset.
n The servo must be OFF.
n The motor must be stopped.
