Jogging - ABB ACS355 User Manual

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
