4.3.3.2 Signal states
Signal states 4- ][Funktion_STO_Signale_DD5
If the safety function STO is not required, 24 VDC must always be
present at the input STO-ENABLE.
Servo amplifier states when using STO-ENABLE:
The safety function STO may only be activated once the motor has
stopped rotating (setpoint = 0 V, speed = 0 min
-1 , input ENABLE (X3/12)
= 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-ENABLE = 0 V)
