Communication monitoring<br />

• The drive does not monitor optional participant channels, which are obliged to supply:<br />

• A control word containing fixed assignment commands other than channel switches (example: fast stop assigned to C213)<br />

• A control word containing fixed assignment preset speeds<br />

• If there is a fixed assignment between a command and the control word bit of an inactive channel, a communication alarm on this network<br />

will not trigger a communication fault.<br />

Example:<br />

A drive is equipped with a "Controller Inside" card and an Ethernet card.<br />

The "Controller Inside" card controls the drive (command and reference).<br />

One bit of the Ethernet control word is assigned to "fast stop".<br />

If the drive is disconnected from the Ethernet network, the drive can no longer be stopped via Ethernet (however, a communication fault is<br />

not triggered).<br />

Enabling of communication channels<br />

• A communication channel is enabled once all the parameters involved have been confirmed.<br />

Example:<br />

A drive is in I/O profile with simple speed control. Modbus constitutes both the command and reference channel.<br />

The Modbus channel will be enabled as soon as the control word and speed reference have been received.<br />

• The drive is only able to start if all obligatory participant channels are enabled.<br />

Example:<br />

A drive in DSP402 profile is connected to Modbus, which is the active channel.<br />

Unless the reference has been written at least once, it will not be possible to proceed to the "5-Operation enabled" state, even if the<br />

"4-Enable operation" command is sent.<br />

Example:<br />

A drive is connected to Modbus.<br />

The terminals are both the reference and command channel.<br />

The operation function is activated and summing input 2 is assigned to Modbus.<br />

The drive will not start until the reference has been supplied by Modbus.<br />

Example:<br />

A drive is configured for switching between the terminals and CANopen.<br />

If the command switch is assigned to the Ethernet card, startup will only be possible once the Ethernet channel is enabled.<br />

• A communication channel is disabled:<br />

• In the event of a communication alarm<br />

• In forced local<br />
