4.2.3

Positioning

For starting a positioning process, 50 actions of the "Positioning" type are provided for the
positioning sequence control. If such an action is active, the basic function "Positioning" is requested
by the L_Sequencer_1 via corresponding control outputs.
• The profile is entered via the parameters of the basic function "Positioning".
• For the 8400 TopLine inverter, 15 different profiles can be parameterised.

A detailed explanation of all profile parameters can be found in the appendix in the
description for the "Positioning" action type.
4.2.4

Holding brake control

This basic function is used for low-wear control of a holding brake.

Danger!
Please note that the holding brake is an important element of the safety concept of the
entire machine.
Thus, proceed very carefully when commissioning this system part!

Detailed information on how to parameterise the holding brake control can be found in
the reference manual/online help of the controller in the chapter "Basic drive functions
(MCK)".
The documentation of the holding brake control contains safety instructions which
must be observed!
Application-specific notes on the holding brake control:
• In the Lenze setting, the mode 0 (brake control off) is preset in C02580.
• The technology application is prepared for the control of a 24 V holding brake via the high
current output (terminal strip X107).
• The application of the holding brake causes controller inhibit, and when the inverter is
inhibited, the following error is reset.
be set in C01215/3 that remains stored even if the controller is inhibited.
• In mode 12 (controlled automatically), the speed thresholds do not apply to the operating
modes with a setpoint request via control signal (e.g. "PosExecute" in the "Positioning"
operating mode). Here the control logics open and close the holding brake by internal
commands in the Motion Control Kernel.
