* XE2 and XEL-XPL STO bypass connections are different.
The diode shown should be used if XE2 and XEL-XPL drives are used on the same
equipment. Otherwise, the diode may be replaced by a jumper.
XE2 STO bypass connectors are not compatible with XEL-XPL drives.

DESCRIPTION
The800-1782providestheSafeTorqueOff(STO)functionasdenedinIEC61800-5-2.Threeopto-couplersareprovidedwhich,whende-energized,
preventtheupperandlowerdevicesinthePWMoutputsfrombeingoperatedbythedigitalcontrolcore.ThisprovidesapositiveOFFcapabilitythat
cannotbeoverriddenbythecontrolrmware,orassociatedhardwarecomponents.Whentheopto-couplersareactivated(currentisowingintheinput
diodes),thecontrolcorewillbeabletocontroltheon/offstateofthePWMoutputs.

totheSTO-IN1andSTO-IN2terminalsofJ6,andthedrivemustbeinanENABLEDstate.Whentheopto-couplersareOFF,thedriveisina

thatwillenergizealloftheopto-couplersfromaninternalcurrent-source.WhenthisisdonetheSTOfeatureisoverriddenandcontrolof
