The user has the ability to select the motor current wave shape. This will help provide even steps 

and minimize motor vibrations for various motors. If you use motors that have a large detent torque 
compared to the motor torque you may need to select a wave form other than 0% wave shape. The wave 
shape corrections are based on a percentage of third harmonic distortion. 
 
 

Switch 1-1 enables and disables the characters from being echoed from the drive. It is best to have 

the echo enabled while debugging. 
 

Switch 1-2 enables or disables the drive from sending a DN response when a move stops. This can 

be used as an indication that the drive has reached the desired position without polling the position status. 
 

Switch 1-3 can be set to output a "CR" carriage return after status 

 

Switches 7 and 8 set the system ID so that the units can be daisy chained.  

 
 

Fault indicators 

 
There are two LED indicators adjacent to the motor terminal.  
 
Fault1 LED is on when Over-current or Over-temperature conditions occur. 
 
Fault1 LED is flashing when under voltage condition occurs. Check AC voltage is selected correctly 
 
Fault2 LED is on when the motor power is removed.
