Precaution for system construction
* Construct system as balance of machine system (load inertia moment, friction, load torque)
will be same in 2 axes. When that balance differs in 2 axes, overload alarm might occur only
in 1 axis.
* At the tandem operation, please use servo motors and amplifiers with a same model
number, in 2 axes.
* Please place safeguard circuit that is able to stop both axes by single axis alarm (like as
power supply breaker).
* When overtravel function is used, construct system as inputting an overtravel status to both
axes with same timing, after sending individual overtravel signal to a host equipment.
* In case that emergency stop function is assigned to general input signal and used, system
shall be constructed so as to input emergency stop signal to both axes.
