APPLICABLE FUNCTIONS
This chapter explains the applicable functions. Please select the applicable function to be used from the following table.
Function to operate safely
Functions to enhance the failure detection capability of the servo amplifier
Functions to prevent the drive of servo motor from stopping
Functions to perform advanced control in specific applications
Functions to store data sampled at high speed from the servo amplifier, then
communicate/output it to the controller
*1 Available on servo amplifiers with firmware version A5 or later.
Applicable function
Outline
Reference

Drive recorder
Stores data at alarm occurrence. The stored data can be used for a
cause analysis.
Scale measurement function
Sends linear encoder data to the servo system controller via the servo
amplifier.

Touch probe
Accurately latches the positions at the rising and falling edges of TPR1
(Touch probe 1), TPR2 (Touch probe 2), and TPR3 (Touch probe 3),
and detects them with precision of 1
μ
s. To latch the current position,
turn the touch probe signal on.
A/B/Z-phase pulse output function
Outputs the position information of the servo motor or the load-side
encoder as A/B/Z-phase pulses. Use this function to execute
synchronous control or other operations.
