motors

[medensat]

Hi guys,
i'm working in a project of a Mitsubishi PLC (FX) , i want to make a program ladder that controls two independent motors one at a time, the standby motor automatically starts in case of failure (coupur energy, default) the first engine.
i program with gx iec developer 7.04, the 2 motors are switch on by (enable1,enable2).
Thanks in advance
