MNEMONIC	FUNCTION	TYPE
H	Hold Program Execution	Program Instruction

DESCRIPTION

The hold instruction is used in a program to suspend program execution. If no parameter is specified the execution of the program will be suspended while motion is in progress. This will typically be used following a MA or MR instruction.

A time in milliseconds may be placed as a parameter to the hold instruction, This will suspend program execution for the specified number of milliseconds

USAGE

H <time> ‘Blank or 0 - hold while moving, 1 - 65000 usec.

EXAMPLE:

‘example 1
MA 20000	‘move absolute 20000 motor units
H	‘hold program execution until motion completes
MA -20000	‘move absolute -20000 motor units
H	‘hold program execution until motion completes
‘example 2
O2=1	‘set output 2 HIGH
H 1000	‘hold 1 second
O2=0	‘set output 2 LOW

RELATED COMMANDS: PG, E

MNEMONIC	FUNCTION	TYPE
HI	Home to Index Mark Variable	Setup Variable

DESCRIPTION

This instruction will find the the encoder index mark. There are four types for this command:

1)Speed (S): Specifies the direction and speed that the axis will move until the index mark is found (VM).

2)Creep (C): Specifies the direction and speed that the axis will move off the index mark until it becomes inactive again (VI).

When HI is executed, the axis moves in the direction specified by the sign of speed at VM. It then creeps off of the switch in the direction specified by the sign of creep at VI. Motion is stopped as soon as the switch becomes deactivated.

USAGE	TYPES
HI=<type>	1: S- C+, 2: S- C-, 3: S+ C-, 4: S+ C+

EXAMPLE:
HM=2	‘Find index mark at VM in the minus direction, Creep off at VI in the minus direction

RELATED COMMANDS: VM, VI, EE, I6

MNEMONIC	FUNCTION		TYPE
HC	Hold Current		Setup Variable
DESCRIPTION
This variable defines the motor holding current in percent.

USAGE	UNITS	RANGE	DEFAULT
HC=<percent>	Percent	0 to 100	5

EXAMPLE:
HC=5	‘Set motor holding current to 5%

RELATED COMMANDS: HT, RC, HI
