Safe Torque Off
6-21
AC30 series Variable Speed Inverter
MINIMUM STO IMPLEMENTATION
This example shows the minimum connections required. To reset from STO requires that STO Request contacts are closed to permit normal drive
operation. The user must do a risk assessment to ensure that all safety requirements are met. The user must select and assess appropriate equipment.
Note:
all wiring shown is within the control cubicle.
To run the drive:
Ensure the STO Request contacts are closed.
Press the DRIVE START button.
To perform operational (not STO) stop:
Press the DRIVE STOP button.
Wait for the motor to come to rest.
To invoke STO:
Press the DRIVE STOP button.
Wait for the motor to come to rest.
Open the STO Request contacts simultaneously. The
contacts must remain open for the entire duration that STO
is required: they must not be momentary action switches.
The drive will confirm via X10/05 that STO has been invoked
by the lamp being ON.
If the lamp is OFF, do not access the machine as a fault may
be present.
Note:
if the STO Request contacts open while the motor is
rotating, the motor will coast to rest (unless external forces
act on it).
