Homing mode

Homing mode

The reference (e.g. zero position of the drive axis in the machine measuring system) can be

defined by reference search or reference setting.

 In the event of a reference search, the drive travels according to the defined homing

mode to detect the reference in the measuring system independently.

 During reference setting, the motor can be homed manually also when the motor is at

standstill. The measuring system is set according to the reference position

parameterised in the object

0x607C

(home offset).

Tip!
A reference search is mainly used for continuously running systems, or if the

traversing range or machine cycle of the drive cannot be represented in the display

area of the encoder, e.g. if incremental encoders are used at the motor, or

singleturn absolute value encoders or resolvers are used at the gearbox.
A reference is mainly set in systems/machines that bear the risk of collisions, or

every time homing cannot be executed (e.g. in the case of a cross cutter having

material in the machine).

Definition of the homing mode
The homing modes of the "Homing" basic function are supported 1:1.

 The homing modes are selected via the 0x55AF (Lenze code C02640) manufacturer-

specific object.

 Alternatively, all CiA402 homing methods are supported. The homing modes are

specified via the object

0x6098

(homing method).

 A detailed process description of the CiA402 homing methods can be found in the

chapter "

Overview of CiA402 homing modes
