4.3.3.2 Signal states
Signal states 4- ][Funktion_STO_Signale
If the safety function STO is not required, 24 VDC must always be con-
nected to the inputs STO1-ENABLE and STO2-ENABLE.
Status conditions of the servo amplifier when using STO1-ENABLE and
STO2-ENABLE:
The safety function STO may only be activated once the motor has
stopped rotating (setpoint = 0 V, speed = 0 min
-1
, input ENABLE (X3B/
1) = 0 V).
The following sequence must be maintained if the drive is to use con-
trolled braking:
1. Controlled braking of the drive (speed setpoint = 0 V)
2. Disable the servo amplifier if speed = 0 min
-1
(ENABLE = 0 V)
3. If a suspended load is present, use an additional mechanical measure
to block the drive
4. Activate safety function STO (STO1-ENABLE and STO2-ENABLE=
0 V)
