4. RESET & EMERGENCY STOP

PMC INTERFACE

When the emergency stop signal *ESP turns to “0”, the emergency stop
is applied to the machine and the Power Mate is reset. This signal is
controlled by the B contacts of a pushbutton switch. The emergency stop
signal turns the servo ready signal (SA[3.2]) to “0”.
Overtravel detection by this Power Mate is handled by the software limit
function, and a limit switch for normal overtravel detection is not needed.
To prevent the machine from moving beyond the software limit through
servo feedback error, always install a stroke end limit switch (shown in
Fig. 4.1 below).
