9.5.1.3 Second homing speed
For the homing modes 0...5 as well as 10 and 11 two different speeds can be parameterised
to reduce the homing time and increase the accuracy:
r The higher speed set in C02644 causes a quick approach of the limit switch/reference
switch.
r After reversing to the limit switch/reference switch the encoder zero pulse/touch
probe sensor is approached slower but more precisely with the lower speed set in
C02646 .
n C02644 : Ref. speed 1
o C02646 : Ref. speed 2
p C02645 : Ref. acceleration 1 (and deceleration 1)
q C02647 : Ref. acceleration 2 (and deceleration 2)
r C02648 : Ref. S-ramp time
s C02643 : Ref. target position
Example: Operation of mode 2:
A. Movement in positive direction.
B. Reversing to positive travel range
limit switch.
C. Negative edge at
HM_bHomingMark enables home
position detection.
D. The following positive edge of the
encoder zero pulse (MP) sets the
reference.
E. Drive has reached defined target
position.
