5.7 DI/DO Function
There are eight DI signals and two DO signals on terminal CN1 of SV820N. H03 (terminal
DI function allocation and logic selection) and H04 (terminal DO function allocation and logic
selection) can be used by multiple axes. On any axis, setting and modifying functions of DI
and DO terminals can be performed on the keypad and the last modication prevails.

and last two digits indicate terminal functions.
Input Function Description
01 S-ON
Servo
enabled
Invalid - In local
mode, servo motor is
disabled.
Valid - In local mode,
servo motor is
enabled.
S-ON function is only valid in non-bus
control mode.
The logic of the corresponding terminal
needs to be set to level valid.
14 P-OT
Positive
limit switch
Valid - Forward drive
is inhibited.
Invalid - Forward drive
is permitted.
When the mechanical movement is
out of range, the overtravel prevention
function is implemented.
It is recommended that the logic of the
corresponding terminal be set to level
valid.
15 years N-OT
Negative
limit switch
Valid - Reverse drive
is inhibited.
Invalid - Reverse
drive is permitted.
When the mechanical movement is
out of range, the overtravel prevention
function is implemented.
It is recommended that the logic of the
corresponding terminal be set to level
valid.

Switch
Home
switch
Invalid - Mechanical
load is out of the
Home switch range.
Valid - Mechanical
load is within the
Home switch range.
The logic selection of the
corresponding terminal must be set to
level valid.
If the logic is set to 2 (rising edge
valid), the servo drive forcibly changes
it to 1 (high level valid). If the logic is
set to 3 (falling edge valid), the servo
drive forcibly changes it to 0 (low level
valid). If the logic is set to 4 (both rising
edge and falling edge valid), the servo
drive forcibly changes it to 0 (low level
valid).

Touch
Probe1
Probe 1
Invalid - Probe is not
triggered.
Valid - Probe can be
triggered.
The logic of probe is only relevant to
the probe function (60B8h) regardless
of the logic selection of terminal.
39
Touch
Probe2
Probe 2
Invalid - Probe is not
triggered;
Valid - Probe can be
triggered.
The logic of probe is only relevant to
the probe function (60B8h) regardless
of the logic selection of terminal.
