0x609A - Homing acceleration
3.9.3 Behaviour of the home position after mains switching
If the reference position/information is to remain available after mains switching, the
setting C02652 = "1: Received" must be selected. Furthermore, the max. permissible angle
of rotation of the encoder, which can be adjusted in C02653, must be observed.
Index | Name:
0x609A | Homing acceleration
Data type: UNSIGNED_32
Code: C03615
For the reference search two accelerations (and decelerations) can be parameterised to reduce homing time and
increase accuracy:
Subindex Name
 0x609A/1 Acc. during search for switch
 0x609A/2 Acc. during search for zero
Index | Name:
0x609A/1 | Acc. during search for switch
Data type: UNSIGNED_32
Code: C02645
Acceleration 1 (and deceleration 1) which causes a quick approach of the limit switch/reference switch (depending
on the mode selected).
• Direct mapping of the Lenze code C02645 (homing: acceleration 1).
Setting range

Index | Name:
0x609A/2 | Acc. during search for zero
Data type: UNSIGNED_32
Code: C02647
Acceleration 2 (and deceleration 2) which causes the touch probe sensor to be approached slower (but more
precisely) after reversing on the limit switch/enabling the reference switch and the subsequent positioning to the
target position.
• Direct mapping of the Lenze code C02647 (homing: acceleration 2).

Note!
When resolvers or single-turn absolute value encoders are used and the mains is
switched off (24 V supply off), the encoder may only be moved by ½ revolution
since otherwise the home position will get lost due to the ambiguity of the
encoder information.
