Jogging
The jogging function is typically used to control a cyclical movement of a machine
section. One push button controls the drive through the whole cycle: When it is on,
the drive starts, accelerates to a preset speed at a preset rate. When it is off, the drive
decelerates to zero speed at a preset rate.
The figure and table below describe the operation of the drive. They also represent
how the drive shifts to normal operation (= jogging inactive) when the drive start
command is switched on. Jog cmd = State of the jogging input, Start cmd = State of
the drive start command.
The function operates on a 2 ms time level
Note: The jogging is not operational when the drive start command is on.

Description
1-2 1 0 Drive accelerates to the jogging speed along the acceleration ramp of the
jogging function.
2-3 1 0 Drive runs at the jogging speed.
3-4 0 0 Drive decelerates to zero speed along the deceleration ramp of the
jogging function.
4-5 0 0 Drive is stopped.
5-6 1 0 Drive accelerates to the jogging speed along the acceleration ramp of the
jogging function.
6-7 1 0 Drive runs at the jogging speed.
7-8 x 1 Normal operation overrides the jogging. Drive accelerates to the speed
reference along the active acceleration ramp.
8-9 x 1 Normal operation overrides the jogging. Drive follows the speed
reference.
9-10 0 0 Drive decelerates to zero speed along the active deceleration ramp.
10-11 0 0 Drive is stopped.
11-12 x 1 Normal operation overrides the jogging. Drive accelerates to the speed
reference along the active acceleration ramp.
12-13 x 1 Normal operation overrides the jogging. Drive follows the speed
reference.
13-14 1 0 Drive decelerates to the jogging speed along the deceleration ramp of the
jogging function.
14-15 1 0 Drive runs at the jogging speed.
15-16 0 0 Drive decelerates to zero speed along the deceleration ramp of the
jogging function.
