Signal lights and reset button + STO with emergency push-button (no functional safety)
This option provides the STO (Safe Torque Off) function via an emergency push-button mounted on the door of the control com-
partment. The control terminals of the control card are extended from inside the drive module and routed out to the terminal block
set -XD2 in the control compartment. The emergency push-button is wired between terminals -XD2.10 and -XD2.19.
Activating the emergency push-button prevents the unit from generating the voltage required to rotate the motor. The option pro-
vides:
Safe Torque Off (STO), as defined by EN IEC 61800-5-2.
Stop Category 0, as defined in EN 60204-1.

Safety Option MCB 150 along with STO function using an emer-
gency stop push-button on the control compartment door. The emergency stop push-button activates the motor deceleration and
makes the motor stop in the set deceleration ramp time. Basic wiring for the S37 terminal of the option card to terminal 37 of con-
trol card and the emergency push-button wiring are provided
MCB 150 is used when the standstill or the motor speed is measured using a TTL encoder. For detailed instructions, refer to the VLT

Motion Control Tool MCT 10 software
to take advantage of the following functional safety features:
Safe Torque Off (STO).
No power is being fed to the motor which can generate a rotation. Stop category 0 to EN IEC 60204-1.
Safe Stop 1 (SS1).
The motor decelerates. Monitoring of deceleration ramp and STO following zero speed, or STO at the end of a deceleration
time. Stop category 1 to EN IEC 60204-1.
Safely limited speed (SLS).
This function prevents exceeding a defined speed value. See the OPT-B option board and safety relay user manuals for the regu-
lations and the certified safety.
