VCC 20
VCC is a +12V power rail provided by the drive. It
can be used for the input on an analog speed or
torque command. Maximum permissible current
100mA.

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 01 ALL 7 6
SRDY is activated when the servo drive is
ready to run. All fault and alarm conditions, if
present, have been cleared.
SON 02
Not
assigned
- -
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)
