Insertion parts under Force Control
4.1 Overview of insertion parts under Force Control
Force Control of insertion parts works between the height where thrust control starts and the
target descent height. (See Fig. 4.1.1)
Thrust control start height is the height where Force Control is started. It is calculated based on
board surface as follows.
(thrust control start height) = [Mount]-[Force Control Distance(mm)] of
[Machine]-[Specification Information]-[Force
Control Specification]-[Sequence]
+
[Parts]-[Shape]Tab-[Body Size Z(mm)]
Target descent height is the height where Force Control is ended. It is calculated besed on
board surface as follows.
(target descent height) = [Mount]-[Force Control Distance(mm)] of
[Machine]-[Specification Information]-[Force
Control Specification]-[Sequence]
+
[Parts]-[Mount]Tab-[Insert Length (mm)]
+
[Parts]-[Mount]Tab-[Mount Height (mm)]
Please note that the value of [Mount Height (mm)] means only pressing ammount, so that the
head acrually reaches the height without [Mount Height (mm)].

4.2 Insertion shortage judgment error
Insert Short Distance Setting
By setting [O:Insert short distance (mm)] for each parts, it is possible to check if insertion is
succeeded or not.
(See Fig. 4.2.1.1)
Fig. 4.2.1.1 Insert Short Distance Setting
*For not insertion parts (N: Insert Length is "0"), it only judges whether or not the parts have
reached the board surface (Judgment based on [Mount] - [Error Judgment Distance(mm)] of
[Machine] - [Specification Information] - [Force Control Specification] - [Sequence]).

Short Insertion Judgment
In mounting action with Force Control on YC8, it judges as short insertion when the height of
inserted parts is over [O:Insert short distance (mm)].
(See Fig. 4.2.2.1)
Fig. 4.2.2.1 Insert Short Judgment
It judges as short insertion in these conditions.
1. Parts itself has not reached the board face, or only 1/5 of [N:Insert Length (mm)] is
inserted. (in this case, “Ea2969: Parts insertion Errors” appears.)
2. More than 1/5 of [N:Insert Length (mm)] is inserted, but the inserted height is over
[O:Insert short distance (mm)]. (in this case, “Ea2974: Parts insertion Errors”
appears.)
