6.1.8 Parameter Setting of DELTA ASDA-A Servo Driver
Monitor if the number of sent and received
pulse is correct by setting this parameter. In
Weihong control system, the correct
quantity of pulse sent by control card is
detected by pulse inspection to determine if
there is electrical interference.
External pulse
input type
X=2: pulse + direction;
Z=0: positive logic
Z=0: during control mode switching, DIO is
maintaining the set value. Since switching
control mode is not used, Z=0
Y=0: forward rotation (CCW) (in terms of
load);
Y=1: the rotation direction is reversed.
X1X0=00: position control mode
Motor stop mode
selection
Y=0: when there is no servo enabled,
motor dynamic brake occurs; Y=1: motor is
free.
X=0: motor stops instantly, X=1: motor
stops with deceleration.
Electronic Gear
Ratio
(Numerator)(N1)
N1/M= encoder pulses × 4× pulse
equivalent× mechanical deceleration ratio/
pitch
Representative value: encoder
pulses=2500, pitch=5mm, pulse
equivalent=0.001, deceleration ratio=1,
calculation as below:
N1/M= 2500×4×0.001/5 = 2 / 1, N1=2,
M=1;
When the multi-electronic gear ratio is not
used, P2-60~ P2-62 are not required.

X1X0=01: digital input (DI1=SON)
corresponds to 9th pin of CN1.
X2 = 1: set DI1 input as NO (normally
open) a-contact point.
Default factory setting of DI6 and DI7 are
NC (normally closed) limit signal input pins;
driver can‘t run without being connected to
pin 32 and pin 31 of CN1.
X2=1: set DI6 and DI7 inputs as NO
(normally open) a-contact points;
X1X0=00, limit signal input of the driver is
not used.
Function setting
for digital input
pin DI8
External EMG stop input is not used.
Function setting
for digital output
pin DO4
DO4 corresponds to pin 1 & pin 26, used
as clamping-position brake signal of Z-axis;
X2=1: set DO4 output as NO (normally
