Scope

Motor specific

Syntax

J-

Remarks

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

Jogging acceleration and velocity are determined by the values of Ix19-Ix22 in force at the

time of this command.

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

Scope

Syntax

Remarks

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 Ix19-Ix21 in force at the time of this command.

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
