12.1.5Jogging

In a jogging motion, the motor is commanded to move in a fixed speed. The acceleration (or deceleration) to the desired speed are the AC and the DC parameters.

Jog motions may be initiated any time by using the JV command, not necessarily from a stationary state. The Jog mode decisions, made every position control cycle, are given in the flow chart below.

Start

JV > 0 and

Yes

Apply DC

Speed > JV?

 

 

JV< 0 and

Yes

Apply DC

Speed < JV?

 

 

Speed = JV?

Yes

Maintain JV

Apply AC

Figure 25 – Jog Decisions Flow Chart

All the parameters of the above flow chart, including AC,DC, JV, and the position target are updated by a BG command, or by its hardware equivalent (refer the IL[N] command).
