ISO/EN 13849 Cat. 3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
Slide Switch S6 controls the polarity of this signal. Refer to
With the Safe Disable monitor output (terminals DM+ and DM-), the drive provides a safety status feedback signal. This signal
should be read by the device that controls the Safe Disable inputs (PLC or a safety relay) in order to prohibit leaving the “Safe
Torque Off” status in case the safety circuit malfunctions. Refer to the instruction manual of the safety device for details on
this function.
Digital Operator Display

ISO/EN 13849 Cat. 3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
When both Safe Disable inputs are open, “Hbb” will flash in the digital operator display.
If one Safe Disable channel is on while the other is off, “HbbF” will flash in the display to indicate that there is a problem in
the safety circuit or in the drive. This display should not appear under normal conditions if the Safe Disable circuit is utilized
properly.
