Digital Output Function Description 
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. 
SON 02 
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.  
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) 
ZSPD 03 
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 
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. 
TSPD 04 
At Speed reached. TSPD is activated once the drive has detected the motor has 
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. 
TPOS 05 
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. 
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. 
ALRM 07 
Servo alarm (Servo fault) activated. ALRM is activated when the drive has detected a 
fault condition.
 
(However, when Reverse limit error, Forward limit error, Emergency 
stop, Serial communication error, and Undervoltage these fault occur, WARN is 
activated first.) 
BRKR 08 
Electromagnetic brake control. BRKR is activated (Actuation of motor brake). (Please 
refer to parameters P1-42 ~ P1-43) 
 
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.
