As shown in Figure 2-10, the two switches in the top machine room must be connected to
the two switches in the bottom machine room in series. The two signals are respectively
connected to X10 and X11. Thus, if any floor plate is removed, both signals have a change.
2.3.4 Connecting Brake Detection Switches in Dual-Motor Application
In the application of dual motors and dual brakes, to satisfy China’s GB standard, obey
the following instructions:
1） Each of the dual motors has a service brake. The two brakes can be controlled by the
same contactor. The contactor is connected to the NO auxiliary contact of the service
brake signal X5
2） The two auxiliary brakes can also be controlled by a contactor. The contactor is
connected to the NO auxiliary contact of the auxiliary brake signal X8.
3） When the service brake is applied, its action switches must be in the OFF
state and be connected according to Figure 3-11.That is, the two action switches of the
brake for motor A are connected in series and used as the input of X6. The two action
switches of the brake for motor B are connected in series and used as the input of X7.
4） When the auxiliary brake is applied, its action switches must be in the OFF
state and be connected according to Figure 3-11.That is, the two action switches of
auxiliary brake A and auxiliary brake B are connected in series and used as the input of
X9.
