Turbo PMAC On-line Command Specification

Turbo PMAC will reject this command if the motor is in a coordinate system that is currently running a
motion program (reporting ERR001 if I6 is 1 or 3).
motion program (reporting ERR001 if I6 is 1 or 3).
Example:
J=0
; Jog addressed motor to position 0
#4J=5000
; Jog Motor 4 to 5000 counts
#8J=-32000
; Jog Motor 8 to -32000 counts

J=*
Function:
Jog to specified variable position
Scope:
Motor specific
Syntax:
J=*
This command causes the addressed motor to jog to the position specified in the motor's “variable jog
position/distance” register. Jogging acceleration and velocity are determined by the values of Ixx19-
Ixx22 in force at the time of this command.
position/distance” register. Jogging acceleration and velocity are determined by the values of Ixx19-
Ixx22 in force at the time of this command.
The variable jog position/distance register is a floating-point register with units of counts. The register is
located at Turbo PMAC address L:$0000D7 for motor 1, L:$000157 for motor 2, etc. It is best accessed
with a floating-point M-variable; the suggested M-variable is Mxx72. The usual procedure is to write the
destination position to this register by assigning a value to the M-variable, then issuing the J=*
command.

Virtually the same result can be obtained by writing to the motor target position register and issuing the
J= command. However, using the J=* command permits the returning to the real target position
afterwards without having to restore the target position register. Also, the J=* command uses a register
whose value is scaled in counts, not fractions of a count.

Example:
M172->L:$0000D7
; Define #1 variable jog position/distance reg.
M172=3000
; Assign position value to register
#1J=*
; Jog Motor 1 to this position
M172=P1*SIN(P2)
; Assign new position value to register
#1J=*
; Jog Motor 1 to this position
#1J=
; Return to prejog target position
