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.
