ON/OFF commands via BACnet
Selecting the macro 54 has the following effect:
● Only the ON/OFF2 command is possible via the terminal strip.
● The higher-level controller cannot turn the motor on or off.
To turn the motor on and off via the higher-level controller, you need to manually interconnect
the ON/OFF1 and OFF2 commands with the PROFIdrive control word:
● Set p0840[0] = r2090.0
● Set p0844[0] = r2090.1
