Do Signals - Delta Electronics AC Servo Drive ASDA-AB User Manual

Signal
Other NC
The Digital Input (DI) and Digital Output (DO) have factory default settings which correspond to the
various servo drive control modes. (See section 1.5). However, both the DI's and DO's can be
programmed independently to meet the requirements of the users.
Detailed in Tables 3.B and 3.C are the DO and DI functions with their corresponding signal name and
wiring schematic. The factory default settings of the DI and DO signals are detailed in Table 3.G and
3.H.
All of the DI's and DO's and their corresponding pin numbers are factory set and non-changeable,
however, all of the assigned signals and control modes are user changeable. For Example, the factory
default setting of DO5 (pins 28/27) can be assigned to DO1 (pins 7/6) 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.

SRDY is activated when the servo drive is
ALL 7 6 ready to run. All fault and alarm conditions, if
present, have been cleared.
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
Not
- -
applied to the servo drive, there may be a
assigned
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 is activated when the drive senses the
motor is equal to or below the Zero Speed
Range setting as defined in parameter P1-
38.
ALL 5 4
For Example, at factory 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.
