Safe standstill with bus option ............................................................................................81

3.10.4.1
The application example described here corresponds to Stop Category 1 as defi-
ned by EN60204-1.
A Stop Category 0 in accordance with EN 60204-1 can be implemented, for exam-
ple by setting the delay time on the Emergency power-off switch to 0. The Com-
pax3 drive will then be turned off immediately in 2 channels and will not be able to
generate any more torque. Please take into consideration that the motor will not
brake and a coasting down of the motor may result in hazards. If this is the case, a
"Safe Standstill" in the stop category 0 is not permitted.

Note:
If the "safe standstill" function of Compax3 is required or used for a
machine or system, the errors:
"Motor_Stalled" and
"Tracking"
is not to be switched off (see page 152, see page 137).
Layout:
2 Compax3 devices (the circuit example is also valid for one or multiple devices,
if it is adapted accordingly)
1 Emergency Power-off module (BH5928.47 manufactured by Dold)
With adjustable delayed deactivation of the Compax3 enable input.
The time must be set so that all axes are at a standstill before the Compax3 con-
trollers are deactivated.
1 safety door monitor (BD5985N made by Dold)
Note: With safety door monitor BD5985N, the safety door must be opened and
closed again every time after turning on the 24 V power supply so that the Emer-
gency power-off module can be acknowledged and reset. To avoid this, safety
door monitors with an additional simulation entry or a corresponding reset circuit
can also be used.
1 Emergency power-off switch
Hazardous area accessible via a safety door with safety door switch S1 and S2
3 buttons (S3, S4, S5)
