Value

 

 

 

 

 

 

 

 

SRDY

01

Servo ready. SRDY is activated when the servo drive is ready to run. All fault and

 

 

alarm conditions, if present, have been cleared.

 

 

 

 

 

 

 

 

 

 

 

 

 

Servo On. SON is activated when control power is applied the servo drive. The drive

 

 

 

 

may or may not be ready to run as a fault / alarm condition may exist.

 

 

SON

02

Servo ON (SON) is “ON” with control power applied to the servo drive, there may be a

 

 

fault condition or not. The servo is not ready to run. Servo ready (SRDY) is “ON”

 

 

 

 

 

 

 

 

where the servo is ready to run, NO fault / alarm exists. (P2-51 should turn servo

 

 

 

 

ready SRDY off / on)

 

 

 

 

At Zero speed. ZSPD is activated when the drive senses the motor is equal to or

 

 

 

 

below the Zero Speed Range setting as defined in parameter P1-38. For Example, at

 

 

ZSPD

03

default ZSPD will be activated when the drive detects the motor rotating at speed at or

 

 

 

 

below 10 r/min. ZSPD will remain activated until the motor speed increases above 10

 

 

 

 

r/min.

 

 

 

 

 

At Speed reached. TSPD is activated once the drive has detected the motor has

 

 

TSPD

04

reached the Target Motor Speed setting as defined in parameter P1-39. TSPD will

 

 

 

 

remain activated until the motor speed drops below the Target Motor Speed.

 

 

 

 

 

 

 

 

 

At Positioning completed.

 

 

 

 

When the drive is in Pt mode, TPOS will be activated when the position error is equal

 

 

 

 

and below the setting value of P1-54.

 

 

TPOS

05

When the drive is in Pr mode, TPOS will be activated when the drive detects that the

 

 

position of the motor is in a –P1-54 to +P1-54 band of the target position.

 

 

 

 

 

 

 

 

For Example, at factory default TPOS will activate once the motor is in -99 pulses

 

 

 

 

range of the target position, then deactivate after it reaches +99 pulses range of the

 

 

 

 

desired position.

 

 

TQL

06

At Torques limit. TQL is activated when the drive has detected that the motor has

 

 

reached the torques limits set by either the parameters P1-12 ~ P1-14 of via an

 

 

 

 

external analog voltage.

 

 

 

 

 

 

 

 

 

Servo alarm (Servo fault) activated. ALRM is activated when the drive has detected a

 

 

ALRM

07

fault condition.

(However, when Reverse limit error, Forward limit error, Emergency

 

 

stop, Serial communication error, and Undervoltage these fault occur, WARN is

 

 

 

 

 

 

 

 

activated first.)

 

 

 

 

 

 

 

 

 

 

Electromagnetic brake control. BRKR is activated (Actuation of motor brake). (Please

 

 

 

 

refer to parameters P1-42 ~ P1-43)

 

 

BRKR

08

 

 

 

 

 

 

 

 

 

HOME

09

Homing completed. HOME is activated when the servo drive has detected that the

 

 

“HOME” sensor (Digital Input 24) has been detected and the home conditions set in

 

 

 

 

parameters P1-47, P1-50, and P1-51 have been satisfied.
