8.8.2.1

Functional settings

In

C01216

, various functional settings regarding behaviour in the case of a changeover to the

"positioning" mode can be made in bit-coded form.

• When this is being done, any mode change must be taken into account.
• Positioning with controller inhibit/enable is also possible if the corresponding setting is made.

Function

Lenze setting

Bit 0 PosAbort at PosInit

When a changeover to "positioning" mode is made, ramping down at the

rate of deceleration set in

C01251

for normal stopping is carried out.

On

Bit 1 PosExecute active at PosInit

When a changeover is made to the "positioning" mode, the specified profile

is immediately executed if the "MCK PosExecute" control bit has also been

set. If the MCK "PosExecute" control bit has not been set, the setpoint is

continued.

Off

Bit 2 Reserved

Off

Bit 3 Reserved

Off

Bit 4 ProfilStart at PosInit

When it is changed to the "Positioning" operating mode, the defined profile

is executed immediately without the need to set the MCK control bit

"PosExecute".

Note: If the FB

L_MckCtrlInterface

writes to the MCK control word due to the

setting in

C01297

, a profile start may be prevented. Remedy: Set bit 0 in

C01297

to "0".

Alternative functions for control bit "PosExecute" ( 517)

Note!

In the case of multiple selection, the "PosAbort at PosInit" function, which can be

activated by means of bit 0, has priority over the other functions (see the following truth

table).
