MNEMONIC	FUNCTION	TYPE
A	Acceleration	Motion Variable

DESCRIPTION

The A Variable sets the peak acceleration that will be reached by the MDrive in steps per second2.

USAGE	UNITS	RANGE	DEFAULT
A=<accl>	Steps/sec2	0 to 1525878997	1000000

EXAMPLE:
A=20000	‘set acceleration to 20000 steps/sec2
A=D	‘set acceleration equal to deceleration

RELATED COMMANDS: D

MNEMONIC	FUNCTION	TYPE
AL	Retrieve All Parameters	Variable

DESCRIPTION

The AL variable is used with the PR (PRINT) instruction to print the value/state of all variables and flags to the terminal program.

USAGE

PR AL

RELATED COMMANDS: PR

MNEMONIC	FUNCTION	TYPE
BD	BAUD Rate	Setup Variable

DESCRIPTION

This variable sets the baud rate for serial communications with the MDrive. It sets the rate for the RS-485 interface. The baud rate is set by indicating the first two digits of the desired rate as shown in the range section below.

In order for the new BAUD rate to take effect, the user must issue the S (SAVE) instruction and then reset the MDrive. When the MDrive is reset, it will communicate at the new BAUD rate.

48 = 4800 bps, 96 = 9600 bps, 19 = 19200 bps, 38 = 38000 bps, 11 = 115200 bps

USAGE	UNITS	RANGE	DEFAULT
BD=<baud>	bits per second	48, 96, 19, 38, 11	9600 bps

EXAMPLE:
BD=96	‘set communications BAUD rate to 9600 bps

RELATED COMMANDS: —
