Figure9 No.17~30 homing method
(1) Homing movement speed
Homing movement speed contains high speed and low speed. Take the direction of the last track in homing movement as a
reference, which with the same direction is low speed movement and opposite is high speed movement.
Take No.30 for example, last track as show in figure9. C section which is the last track of homing movement, its direction is
leftwards. Therefore, A/C section whose direction is leftwards are low speed. B section whose direction is rightwards are low
speed.
(2) Track description
Take No. 27~30 homing mode for example, above tracks in the same figure, is to facilitate describe similar track's homing
mode, also facilitate compare differentials. As shown in figure 9, tracks can be divided into three segments according to the
different initial position:
Initial position 1 (between home switch and positive limit)
Sliding block move from the right of the home switch to the left, after meeting the home switch,
a. Under No.28 homing mode, the sliding block will stop immediately.
b. Under No.27 homing mode, the sliding block will slow down to 0, then turn right to stop immediately when meeting the
home switch again.
c. Under No 29/30 homing mode, the sliding block will move left until leaving the home switch,
Under No.30 homing mode, the sliding block will stop immediately
Under No.29 homing mode, the sliding block will slow down to 0 , then turn right to stop immediately when meeting
home switch again.
Initial position 2 ( at home switch)
Sliding block start to move at the status of home switch is triggered,
a. Under No.27/28 homing mode, the sliding block will move right until leaving the home switch
Under No.27 homing mode, the sliding block will stop immediately
