Wiring Notes 

l

 

In order to improve anti-interference performance of the drive, it is recommended to use twisted 
pair shield cable. 

l

 

To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should 
not be tied up together. It is better to separate them by at least 10 cm, otherwise the disturbing 
signals  generated  by  motor  will  easily  disturb  pulse  direction  signals,  causing  motor  position 
error, system instability and other failures. 

l

 

If a power supply serves several drives, separately connecting the drives is recommended instead 
of daisy-chaining. 

l

 

It is prohibited to pull and plug power connector while the drive is powered ON, because there is 
high current flowing through motor coils (even when motor is at standstill). Pulling or plugging 
power connector with power on will cause extremely high back-EMF voltage surge, which may 
damage the drive. 

Configuration 

When the default settings of the easy servo drives are not suitable for your application, it is necessary 
to  configure  it  via  the  on  board  HMI  or  the  configuration  software  ProTuner.  Otherwise  you  may 
encounter problems like high motor heating, big motor noise or even motor stall due to weak torque. 
For a quick start of the easy servo drive, there are not much parameters need to be configured. The 
following table gives the most significant settings of the easy servo drives.

Auto Tuning at Power-up

: It is possible to disable this feature in the setup software in order to tune 

the current loop Kp and current loop Ki manually if the auto tuning result is not good enough. This 
happens when the motor
