Figure 6-9: RS232 interface connection 

Testing the servo 

You may wish to secure the motor so it can

t jump off the bench. Turn on the power 

supply,  the  green  (Power)  LED  will  light.  The  DCS303  has  default  parameters 

stored  in  the  driver.  If  the  system  has  no  hardware  and  wirings  problem,  the  motor 

should be locked and the driver should be ready. 

If  the  motor  jumps  slightly  and  the  red  LED  immediately  turns  on  (flickers),  then 

either  the  motor  or  the  encoder  is  wired  in  reversal.  Open  the  tuning  software 

ProTuner  and  check  driver  status  by  clicking 

Err_check

.  If  it

Phase  Error

,  then 

reversal  motor  wires  or  exchange  encoder  inputs  and  try  again.  If  it

Encoder 

Error

,  please  check  encoder  and  its  wirings,  and  then  try  again.  If  it  still  doesn

work  after  you  followed  all  of  the  previous  steps,  please  contact  us  at 

[email protected]

If  the  red  LED  is  off  and  the  motor  is  normal,  then  you  can  start  to  tune  the  servo 

with 

ProTuner

.  However,  we  recommend  you  see  the  following  contents  before 

starting tuning.
