9.2.13 Drive: Enable OFF3 (BICO interconnection)
To be able to release and stop the drive externally, e.g. via a PLC user program,
connect digital input X122.2 on the Control Unit and use the BICO interconnec-
tion with parameter ”p849[0] BI: 2. OFF3” to connect:
S Drive: p849[0] BI: 2. OFF3
S Control Unit: Control_Unit, r722: Bit1, CO/BO: CU digital inputs, status: : DI 1
(X122.2) (0=Low/1=High)
With reference to SIMODRIVE drives this corresponds to the effect of digital
input X122.1 on terminal 663 (pulse enable) with prior deceleration of the drive.
The
OFF3 braking ramp can be configured drive–specifically via the parameters: p1135,
p1136 and p1137.
Perform the following actions for each drive:
1. Double–click Project > Drive_Unit_Addr10 > Drives > <Drive> > Control
Logic to open control logic configuration in the project navigator.
2. Click the binector input symbol of signal ”p845[0] BI: 2. OFF2” and from the
list select Control_Unit > Further interconnections > r722: Bit1, CO/BO: CU
digital inputs, status: : DI 1 (X122.2) (0=Low/1=High)
