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.

X (Examine)
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)

(Y) Hold and Run Current
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.
