6.5 STOActivation
To enable the axis, you must enable the STO circuit. The 24 V power of the STO circuit must be
integrated within the emergency fail-safe loop. See Safe Torque Off Safety Function on page 140.
WARNING: Electrical hazard - AVERTISSEMENT: risque électrique.
The DM2020 system and connected motor may present an electrical hazard if the
safety precautions are not observed, which may result in death or serious injury to
personnel, or damage to equipment.
Ø Before attempting this operation, follow the safety information and procedures
in General Hazards and Safeguards on page 20.
WARNING: Mechanical hazard - AVERTISSEMENT: risque mécanique.
The DM2020 system and connected motor may present a mechanical hazard if the
safety precautions are not observed, which may result in death or serious injury to
personnel, or damage to equipment.
Ø Before attempting this operation, follow the safety information and procedures
in General Hazards and Safeguards on page 20.
l
Always check the STO function at the first system start up or after any system maintenance.
l
Do not attempt to access a protected area (safety interlocked cover, door, barrier, etc.) while
the machine is powered up or operating. Doing so triggers the emergency stop chain, which
interrupts motor power, and causes the intervention of the STO.
l
If the STO signal is not removed following the correct sequence, the display will show "F"
(Fault).
6.6 Auto-Phase Procedure
The auto-phasing is set through the Dx2020 GUI software.
The DM2020 system provides an auto-phasing procedure that is useful for unknown motors. This
procedure finds the right phasing angle (THETA) to properly run the motor. At the end of the procedure
the THETA parameter is automatically set. It can be done also to check the correct wiring of the motor.
The motor must be free to move during the auto-phasing procedure.
To set the autophasing, select "Modes and Commands" in the Navigation Area.
