12.4 Manual jog
The basic function "Manual jog" serves to traverse the drive manually, e.g. to clean or exchange the
tool.
• As an option, it is possible to change over to a second speed during traversing.
• "Retraction" of operated (travel range) limit switches is also supported. Only traversing in the
corresponding retracting direction is then possible.

Danger!
During manual jogging, specially assigned profile parameters are active. If they have not
been set correctly, the drive can engage in uncontrolled movement!

Stop!
In manual mode a travel range monitoring via limit switches and software limit
positions is carried out via the basic function " Limiter ". ( 536)
If no limit switches are connected and no software limit positions are set, and the
reference is not known, the drive can travel into a mechanical barrier during manual
mode and machine parts can be destroyed or damaged!

Note!
For manual jog setpoint speeds greater than 30000 rpm are not possible. The speeds
defined for these basic function are internally limited to 30000 rpm.
When the basic function is activated, a start acceleration is considered.

The following applies to the encoderless motor control types :
If no position controller has been selected for position control in case of V/f control or
sensorless vector control ( C02570 = "1: Phase controller is active"), the manual jog is only
executed via the speed profile resulting from the manual jog parameters.
