Information regarding bus control:
Digital outputs can be set with the user bits in the control word.
DOUT1: P480 [-11] = Bit8 bus controlword, setting 83/84
DOUT2: P480 [-12] = Bit9 bus controlword, setting 83/84
With P420, the digital outputs can be directly linked to a digital input P420 [-01 … -04], setting value 83/84.
P420 and P480 have priority over P343.

Brake control
(only for Size 2 and
higher)
Connection and control of an electromechanical brake. The device generated an
output voltage. It depends on the mains voltage. The assignment of the correct
brake coil voltage must be considered in the selection.
Connected loads:
( Section 2.6.5.4 "Electromechanical
brake (optionally with size 2 and above))")
Current: ≤ 500 mA
Permissible cycle time:
up to 150 Nm ≤ 1/s
up to 250 Nm ≤ 0.5/s
