Safe Torque Off (STO)

 
The STO Function can be used for disabling the energy to the motor. The motor will thereby be set in a state where it produces no torque.
 
The STO function have its own input connector mounted at the front of the motor. 
 
It is a two input system and it is required that both inputs are activated (applied with a voltage) before the motor is energized and can operate normally.
 
The STO is only available on following products for Servo motors: MAC400, MAC1500, MAC3000, and for Stepper Motors: MIS17xQ/R/S/T and MIS23x/Q/R/S/T
 
 
Important general information:
  • The STO function is not approved by any third party laboratory (only pendent)
  • Please notice that removing the energy from the motor by use of the STO function do not necessarily stop the motor rotation since any attached load inertia will have an influence when the movement is stopped fully
  • The person that install and service the motor must have a general knowledge concerning electrical equipment and safety functions
  • The STO function is considered as functional and reliable for 20 years
 

How to connect and use the STO function.
 
The STO connector contains the two enable inputs STOA and STOB. Both inputs must be applied nominal +24VDC in order to energize the motor and make any motor movement possible.
 
If only one of the inputs is not applied +24VDC the internal STO circuit will remove the energy from the motor.
The illustration below shows the pinout of the connector
 
 
 
Disabling the STO function.
 
If the STO function is not needed the plug JVL type WI1028-M08M3STO must be inserted in the STO connector.
 
The need of this external plug to disable the STO function is to obtain a high safety level and make sure that no misunderstandings will occur concerning whether the STO function is active or not.
