The controller will remain in an idle state for the specified time. The Wait command, if issued while indexing 
(as a result of an R, +, -, or F command), timing will NOT start until the motion has completed.  

 

NV default =0   
 
The following example program pre-energizes the controller to the run current then makes a move. 

P 0 

Enter program mode. 

w 25 

Pre-energize the controller for 250 milliseconds. 

+ 1000 

Move 1000 steps in the plus direction. 

 

P 0 

Exit program mode.

The Examine command produces two different responses, depending on the mode of operation. When NOT 
in the multi-axis mo de (non-daisy chain or party line) the display is as follows: 
 

X    K= 5/5, I= 400, V= 5016, D= 1, ½, n=C 

 

Where: 
 

K= Ramp up/ramp down 

 

I= Initial velocity 

 

V= Slew velocity 

 

D= Divide factor 

 

½= Resolution mode 

 

n= Axis name 

 
In the multi-axis (daisy chain or party line) mode the data is returned in the following format: 

 

mm[LF] 
mm= model (26)

Mnemonic 
 
(Name) Y 

Data 1 
 
Hold 0-100 

Data 2 
 
Run 0-100 

Result 
 

This command allows specifying the Hold and Run values of motor current (per phase) between 0 and 100% 
with a resolution of 1%. The value 100% represents a maximum of 4 amps per phase. The switching between 
Hold and Run values is automatic whenever a motion function is executed. Current reduction to the "Hold" 
value is automatic and occurs when stationary. A settling time (nominally 1 second) is inserted after each 
move is completed. 
 
The maximum current is limited to a value that will not consume more than the 100VA and is available from 
your power supply.
