Explanation
Fieldbus interface bau‐
drate (Factory setting: 6)
Fieldbus interface address (Factory setting: 1)
Valid USS addresses: 0 ... 127.
The parameter is only active if address 0 is set at the Control Unit address switch.
A change only becomes active after the inverter power supply is switched off and switched
on again.
Fieldbus interface times [0] maximum permissible processing time (APDU timeout)
Fieldbus SS BACnet

Fieldbus interface BACnet COV increment
Change in value at which point the inverter sends and UnConfirmedCOVNotification or
and ConfirmedCOVNotification.

Explanation
The motor brakes with the ramp-down
time p1121 of the ramp-function gen‐
erator. The inverter switches off the
motor at standstill.
The inverter goes into the "ready"
state. If, in addition bit 3 = 1, then the
inverter switches on the motor.
Switch off the motor immediately, the
motor then coasts down to a standstill.
The motor can be switched on (ON
command).
