Speed control features
Jogging
Two jogging functions (1 or 2) are available. When a jogging function is activated,
the drive starts and accelerates to the defined jogging speed along the defined
jogging acceleration ramp. When the function is deactivated, the drive decelerates to
a stop along the defined jogging deceleration ramp. One push button can be used to
start and stop the drive during jogging. The jogging function is typically used during
servicing or commissioning to control the machinery locally.
Jogging functions 1 and 2 are activated by a parameter or through fieldbus. For
activation through fieldbus, see
The figure and table below describe the operation of the drive during jogging. (Note
that they cannot be directly applied to jogging commands through fieldbus as those
require no enable signal; see parameter
.) 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; Jog enable = Jogging
enabled by the source set by parameter
; Start cmd = State of
the drive start command.
