Turbo PMAC/PMAC2 Software Reference

Turbo PMAC On-line Command Specification 333

J-

Function: Jog Negative

Scope: Motor specific

Syntax: J-

This command causes the addressed motor to jog in the negative direction indefinitely. Jogging

acceleration and velocity are determined by the values of Ixx19-Ixx22 in force at the time of this

command.

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).

Example:

J- ; Jog addressed motor negative

#5J- ; Jog Motor 5 negative

#3J-#4J- ; Jog Motors 3 and 4 negative

I-variables Ixx19-Ixx22

On-line commands J+, J/, J=, J={constant}, J:{constant}, J^{constant}

Function: Jog Stop

Scope: Motor specific

Syntax: J/

This command causes the addressed motor to stop jogging. It also restores position control if the motor's

servo loop has been opened (enabled or killed), with the new commanded position set equal to the actual

position at the time of the J/ command. Jogging deceleration is determined by the values of Ixx19-Ixx21

in force at the time of this command.

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).

Example:

#1J+ ; Jog Motor 1 positive

J/ ; Stop jogging Motor 1

O5 ; Open-loop output of 5% on Motor 1

O0 ; Open loop output of 0%

J/ ; Restore closed-loop control

K ; Kill output

J/ ; Restore closed-loop control
