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:
ENABLE
0 V
24 V
0 V
24 V
The safety function STO may only be activated once the motor has
stopped rotating (setpoint = 0 V, speed = 0 min
= 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
3. If a suspended load is present, use an additional mechanical measure
to block the drive
4. Activate safety function (STO-ENABLE = 0 V)
