AMS DCB-274 manual Examine, Hold and Run Current

ADVANCED MICRO SYSTEMS, INC. SMC-27X2 SOFTWARE

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.
