Accelnet
safe torque off (sto)
The Safe Torque off (STo) function is defined in IeC 61800-5-2.
Two channels are provided which, when de-energized, prevent
the upper and lower devices in the PWM outputs from being
operated by the digital control core.

InSTallaTIon

Refer to the Accelnet & Stepnet Plus Panels STO Manual
The information provided in the Accelnet & Stepnet Plus Panels STO Manual must be considered for
any application using the BE2 drive's STo feature.
DANGER
FAiluRE TO hEED ThiS wARNiNG CAN CAuSE EquiPMENT DAMAGE, iNjuRy, OR DEATh.
STo ByPaSS (muTInG)
In order for the PWm outputs of the Be2 to be activated, current
must be flowing through all of the opto-couplers that are
connected 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 Safe Torque off (STo) state and the PWm
outputs cannot be activated by the control core to drive a motor.
funCTIonal dIaGram
Current must flow
* STo bypass connections on the BE2 and
xenus xel-xPl models are different. If both
drives are installed in the same cabinet, the
diode should be wired as shown to prevent
damage that could occur if the STo bypass
connectors are installed on the wrong drive.
The diode is not required for STo bypass
on the BE2 and can be replaced by a wire
between pins 7 and 9.

2-Axis Panel EtherCAT
This provides a positive oFF capability that cannot be overridden
by the control firmware, or associated hardware components.
When the opto-couplers are energized (current is flowing in the
input diodes), the control core will be able to control the on/off
state of the PWM outputs.
This diagram shows connections 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 the output PWM stage is
under control of the digital control core.
if not using the STO feature, these connections must be
made in order for the BE2 to be enabled.
