Jogging - ABB ACS350 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.

x = state can be either 1 or 0.
Note: The jogging is not operational when the drive start command is on.
Note: The jogging speed overrides the constant speeds.
Note: The jogging uses ramp stop even if parameter
selection is COAST.
Note: The ramp shape time is set to zero during the jogging (i.e. linear ramp).
