DO 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 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 rpm. ZSPD will remain activated until the motor speed increases above 10 RPM.
TSPD 04 Speed reached. TSPD is activated once the drive has detected the motor has
reached the Target Rotation Speed setting as defined in parameter P1-39. TSPD will
remain activated until the motor speed drops below the Target Rotation Speed.
TPOS 05 Positioning completed.
1. 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.
2. 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 Reached torques limits. 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 output (Servo fault). ALRM is activated when the drive has detected a
fault condition.
BRKR 08 Electromagnetic brake. BRKR is activated actuation of motor brake. (Please refer to
parameters P1-42 ~ P1-43)

HOME 09 Home 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.
OLW 10 Output overload warning. OLW is activated when the servo drive has detected that
the motor has reached the output overload level set by parameter P1-56.
