Chapter 3 Connections and Wiring|ASDA-B Series
3-14 Revision February 2008, Doc. Name: 2006PDD23000009
All of the DI's and DO's and their corresponding pin numbers are factory set and nonchangeable,
however, all of the assigned signals and control modes are user changeable. For Example, the factory
default setting of DO1 (pin 16) is SRDY (servo ready) signal, but it can be assigned to SON (Servo On)
signal and vise versa.
The following Tables 3.B and 3.C detail the functions, applicable operational modes, signal name and
relevant wiring schematic of the default DI and DO signals.

Wiring Diagram
(Refer to 3.3.3)
SRDY ALL
16
(DO1)
SRDY is activated when the servo drive is
ready to run. All fault and alarm conditions, if
present, have been cleared.
SON ALL -
SON is activated when control power is
applied to 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.
ZSPD ALL
2
(DO2)
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 ALL -
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 P -
When the drive is in P mode, TPOS will be
activated when the position error is equal and
below the setting value of P1-54.
TQL ALL -
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.
ALRM ALL
1
(DO3)
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 ALL - BRKR is activated actuation of motor brake.
OLW ALL -
OLW is activated when the servo drive has
detected that the motor has reached the
output overload level set by parameter P2-37.
