6.14.11 Functional test

You must test the safe torque off function after initial start of the drive, after each interference
into the wiring of the drive, or after exchange of one or several components of the drive.

6.14.11.1 Global STO

First Method:
1. Stop drives in the string with setpoint 0 V. Keep drives enabled.
DANGER: Do not enter hazardous area!
2. Activate the global STO function for example by opening protective screen of the string,
where the drives are connected (voltage at AKD-C X16/6 or X16/8 0V).
3. The AKD-C fault contact opens, the corresponding string STO-Status message (X16/1 or
X16/2) changes the voltage level, the drives lose torque and slow down to zero speed
without control.
Second Method:
1. Stop all drives in the string with setpoint 0 V, disable the string.
2. Activate the global STO function, for example, by opening protective screen (voltage at
AKD-C X16/6 or X16/8 0V)
3. The corresponding string STO-Status message (X16/1 or X16/2) changes the voltage
level, the string cannot be enabled.

6.14.11.2 Local STO

First Method:
1. Stop the drive with setpoint 0 V. Keep drive enabled.
DANGER: Do not enter hazardous area!
2. Activate the local STO function for example by opening protective screen of the drive,
(voltage at AKD-N X6/1 0V).
3. The drive lose toque and slows down to zero speed without control.
Second Method:
1. Stop the drive with setpoint 0 V, disable drive.
2. Activate the STO function, for example, by opening protective screen (voltage at AKD-N
X6/1 0V)
3. The drive cannot be enabled.
