1 Outline
When configurating the station axes in the XRC and using a single motor to control an axis
with a heavy load applied during an operation, a large-capacity motor with sufficient capacity
and torque is required.
In this case, the station axis becomes very large and requires a wide space for equipment
installation.
A system, where a station axis with a heavy load is operated by two motors may be built to
provide the necessary motor capacity and torque.
In such a system, the two motors must be operated at the same time, or the system and sta-
tion axes may be damaged.
Use the twin drive function to operate the motor on the slave axis side at the same time as the
station master axis during teaching.
This function economizes on system space and obtains sufficient motor power.
