Overview and Operations

Overview

To effectively control machine operations, a proper gain adjustment must be enabled by SV series.

This is done through auto tuning, Gain search PRO or Gain tuning PRO.

The following tuning functions are available:

■ The availability of operation mode and tuning function

All tuning functions can be used by the position control mode.

Speed control mode may use all tuning functions other than Gain search PRO (w/ higher-level command) and Gain

tuning PRO (response characteristic level adjustment).

Only the Gain tuning PRO (stability level adjustment) is available to torque control mode .

Function Description

Auto tuning

This allows servo amplifier to automatically adjust response characteristic to ensure stable response.

A notch filter can be automatically adjusted to minimize mechanical resonance.

This is done simply by adjusting the response

characteristic

Gain search PRO

The servo amplifier automatically executes gain control by measuring mechanical characteristics.

Two methods are available: the "W/o higher-level command" whereby the servo motor gain is

automatically adjusted within a setting range (CW and CCW); and the "W/ higher-level

command" whereby commands from higher-level positioning/motion unit are used for an

automatic gain adjustment.

This delivers a finer control than auto tuning.

Gain tuning PRO

This allows, on one hand, manual adjustment of response and stability level, and on the other

hand, receiving commands from higher-level positioning/motion unit to control the servo motor,

until an optimal gain is achieved.

This method takes a longer time due to manual adjustment and adjustment effect check. But

this method delivers a much finer adjustment.

Anti-resonance control This helps to suppress 100 to 1000Hz continuous vibration generated when gain is increased.

Vibration suppression

This helps to suppress 1 to 100Hz intermittent vibration generated by for example pedestal

vibration.
