11.11.2.4 Limitations

Limit values for the basic functions "Manual jog", "Homing" and "Positioning" can be set via the

following parameters:

• The parameters depend on the mechanics (e.g. the tool used).

• Usually the parameters must be changed when a tool is exchanged, e.g. by means of a recipe

management of a superimposed control or via an HMI ("Human Machine Interface").

• If the limit values are switched effectively and a limit value that is set is exceeded:

• The setpoints of the active basic function ("Manual jog

", "Homing" or "Positioning") are

changed (limited).

• The response parameterised in C02716/3

(Lenze setting: "No response") is activated.

• A corresponding error message is entered into the logbook of the controller.

• A corresponding status is output via the LIM_dnState output.

• The display parameter "Limitation active" (C02715

) is set to "1: Activated".

Parameter Info

C02703

Max. speed

• Max. permissible speed that can be driven by the system.

• This parameter depends, among other things, on the max. motor speed.

C02705

Max. acceleration

• Max. permissible acceleration or deceleration for positioning processes.

• This parameter depends, among other things, on the motor torque and moment of

inertia of the entire mechanics which is driven during the positioning process.

C02706

Min. S-ramp time

 Note!

In order that the set limit values are effective, "1" must be selected in C02702.

• Irrespective of this setting, basically, the speed setpoint is limited to the motor

reference speed (C00011

)!

The limitations are not effective for the basic functions "Speed follower

", "Torque

follower" and "Position follower"!

• In case of these basic functions only speed and acceleration are monitored.

• If the limit values for speed and acceleration are exceeded, the response

parameterised in C02716/3

is activated (Lenze setting: no response).

• Background: In the case of technology applications which are synchronised via an

electrical shaft, the setpoint followers may not be limited, since synchronism would

be lost by this. A possible consequence would be a collision of tools.
