Jogging

Function description
The "Jog" function is typically used to slowly move a machine part, e.g. a conveyor belt. The
"Jog mode" can also be used to move a drive into the required position independent of the
sequence.
The jog mode can be selected via digital inputs or fieldbus (e.g. PROFIBUS). This means that
the setpoint is specified via p1058[0...n] and p1059[0...n].
When a jog signal is present, the motor is accelerated to the jog setpoint with the acceleration
ramp of the ramp-function generator (referred to the maximum speed p1082; see figure "Flow
diagram: Jog 1 and jog 2"). After the jog signal has been deselected, the motor is decelerated
via the set ramp of the ramp-function generator.
Note
The "Jog" function is not PROFIdrive-compliant!
