Output signals
5.5.1
Digital output signals
2.5.1.1
Main Circuit Breaker 1 Close Control ID1218 “MCB1 Close Cont”
AFE contactor, fixed to the relay output B.2.
When P2.5.1.2 is not activated, this output will stay high as long as MCB must be closed.
When the signal goes low, MCB must be open.
When P2.5.1.2 is activated, this gives only a closing command with a 2 s pulse.
2.5.1.2
Main Circuit Breaker 1 Open Control ID1219 “MCB1 Open Cont”
When this output is selected above 0.9, the drive will use pulse control for the MCB
breaker. P2.5.1.1 is used to close the breaker with a 2 s pulse.
The opening command is given by P2.5.1.2 with a 2 s pulse.
2.5.1.3 Ready ID432
The AC drive is ready to operate.
2.5.1.4 Run ID433
The AC drive operates (the drive is modulating).
2.5.1.5 Common
Fault
ID434
A fault trip has occurred.
2.5.1.6 Fault,
Inverted
No fault trip has occurred.
2.5.1.7 At
Reference
The output frequency has reached the set reference. In AFE mode, when DC voltage level
is on setpoint.
2.5.1.8
Overtemperature Warning
The heatsink temperature exceeds unit temperature warning limit.
2.5.1.9 Warning
A general warning signal. The warning will go low when the reset command is given.
2.5.1.10
Circuit Breaker 2 Close Control ID1709
“CB2 Close Cont”
A second AFE contactor control. The drive can connect to two different networks. This
will control the main circuit breaker of the second network.
2.5.1.11
NET Contactor Control
The NET contactor control. Contactor control for Grid where the drive will be
synchronised. This grid is usually the shore supply. When P2.4.2.12 NET Contactor
feedback is received, the drive will change the operation mode to AFE mode.
2.5.1.12 D7
Synchronized
The drive is synchronised to the D7 card. Information is sent, for example, to PLC that
the drive is synchronised to an external network (where D7 is connected). This output
cannot be used to control the NET contactor. There is a separate output signal for that
purpose.
