11.6.2.6 Homing to end stop

By selecting the homing modes 14 & 15, homing to end stop can be executed as follows:

1. The drive travels with reduced torque in positive direction (mode 14) or negative direction

(mode 15).

2. When the drive hits an end stop so that the torque limit set in C02649

is exceeded for the

blocking time defined in C02650

, the reference is set.

• If a reference offset is set, traversing takes place around this offset in a correctly signed

manner.

Mode 14: positive direction to torque limit

( 438)

Mode 15: negative direction to torque limit

( 438)

11.6.2.7 Connection of reference switch

For the homing modes with reference switch, the HM_bHomingMark control input must be

connected to the digital input which is connected to the reference switch.

11.6.2.8 Touch probe interface configuration

The touch probe channel to be used for homing with touch probe detection in »Engineer« is selected

on the Application parameters tab in the dialog level Overview  All basic functions  Homing  TP

interface.

• The setting carried out in this parameterisation dialog directly affects the setting of C02651

("Homing: TP configuration") and vice versa.

• For directly setting C02651

(e. g. by means of the keypad) the corresponding decimal values are

listed for all configuration options in the following table:

• Example: For selecting the touch probe channel "Digital input 1" and a response only to a

negative edge, the decimal value "2" has to be set in C02651

.
