5.4.2.8 Parameter Setting of DELTA ASDA-A Servo Driver
Monitor if the number of sent and received
pulses is correct by setting this parameter. In
Weihong control system, the correct quantity
of pulses 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=1: negative 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,
