02
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 in order to determine whether
there is electrical interference.

X=2: pulse + direction;
Z=1: negative logic.
P1-01 Set control mode
ZYX1X0
0000
Z=0: during control mode switching, DIO
is maintaining the set value. Since
switching control mode is not used, Z=0;
Y=0: positive rotation (CCW) (from the
view of load);
Y=1: negative rotation (CCW)
X1X0=00: position control mode

calculation
N1/M= mechanical deceleration ratio × 4
× encoder pulses × pulse equivalent /
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.

Digital Input Pin 1
(DI1)
X2X1X0
101
X1X0=01: digital input (DI1 = SON)
corresponds to 9th pin of CN1.
X2=1: set DI1 input as NO (normally
open) a-contact point.

for digital input pin
DI6
X2X1X0
100
Default factory setting of DI6 and DI7 is
NC (normally closed) limit signal input;
driver can‘t run without being connected
to pin 32 and pin 31 of CN1.
X2=1: set DI6 and DI7 inputs as NO
a-contact points.
X1X0=00, limit input of driver is not used.
