G1: Gantry axes
Supplementary conditions
The following supplementary conditions apply to a gantry grouping:
? A gantry grouping must not contain a spindle.
? A synchronous axis must not be a concurrent POS axis.
? A synchronous axis must not belong to a transformation.
? A synchronous axis must not be a following axis of another axis coupling.
? A synchronous axis must not be a leading axis of another axis coupling.
A maximum of 8 gantry groupings can be defined.最大8组龙门。
A gantry grouping can have a maximum of 2 synchronous axes.每组1个主动，2个同步。2个同步轴有待实验，37100若是第一组，难道分别设1，11，21？资料上没讲，风险很大，必须实验求证。从840d中：
A total of up to 3 (8 in SW 7.1 and higher) gantry groupings can be defined.
Each gantry grouping consists of one leading axis and one or two synchronized axes.看是可以实现的。

TE3: Speed/torque coupling, master-slave
General boundary conditions
The following boundary condition must be observed:
? A slave axis can only be assigned to one master axis
? One master axis can be assigned several slave axes；需要落实最大从动轴数，肯定大于3
? A slave axis must not be a master axis or be in another master-slave relationship.
