1.4 Function list

The following table lists the functions of this servo. For details of the functions, refer to the corresponding chapters and sections.

Function		Description			Refer to
High-resolution encoder	High-resolution encoder of 131072 pulses/rev is used as a servo motor encoder.
Absolute position detection	Merely setting a home position once makes home position return unnecessary				Chapter 13
system	at every power-on.
Adaptive vibration	Servo amplifier detects mechanical resonance and sets filter characteristics				Section 7.3
suppression control	automatically to suppress mechanical vibration.
Low-pass filter	Suppresses high-frequency resonance which occurs as servo system response is				Section 7.4
	increased.
	Analyzes the frequency characteristic of the mechanical system by simply
Machine analyzer function	connecting a servo configuration software-installed personal computer and
	servo amplifier.
Machine simulation	Can simulate machine motions on a personal computer screen on the basis of
	the machine analyzer results.
Gain search function	Personal computer changes gains automatically and searches for overshoot-
	free gains in a short time.
Slight vibration suppression	Suppresses vibration of	1 pulse produced at a servo motor stop.			Parameter No.24
control
	Automatically adjusts the gain to optimum value if load applied to the servo
Auto tuning	motor shaft varies. Higher in performance than MELSERVO-J2 series servo				Chapter 6

Output signal (DO) forced	Output signal can be forced on/off independently of the servo status.				Section 4.4
output	Use this function for output signal wiring check, etc.				(1) (e)
Test operation mode	Servo motor can be run from the operation section of the servo amplifier				Section 4.4
	without the start signal entered.
Analog monitor output	Servo status is output in terms of voltage in real time.				Parameter No. 22
Servo configuration software	Using a personal computer, parameter setting, test operation, status display,				Section 12.1.7
	etc. can be performed.
