8.10 SmartWire-DT diagnostics
The DS7-SWD soft starter sends diagnostic messages for itself and,
optionally, for the PKE motor-protective circuit-breaker.
Basically, a distinction must be drawn between:
• Basic diagnostics (basic SmartWire-DT diagnostics),
• Advanced diagnostics (advanced SmartWire-DT diagnostics) and
• PROFIdrive parameter channel diagnostics
PROFIdrive parameter channel diagnostics are shown with error messages
or warnings, as applicable, in the cyclic profile with PROFIdrive (profiles 7, 8,
9, 11).
8.10.1 Basic SWD Diagnostics
A pending diagnostic message from the DS7-SWD soft starter will be
signalled as a collective diagnostic in the cyclic profile with input byte 0, bit 4
(DIAG). A device response, if any, will be described in the advanced
diagnostics.
In addition, in profiles 4 to 11, the following bits
• ERR (DS7-SWD stops)
• WARN (no response from DS7-SWD)
in the corresponding input bytes are used to show whether there are any
diagnostic messages (i.e. errors or warnings).
Once you fix the fault’s cause, you can acknowledge a fault (ERR) as follows:
• Profiles 1, 2, and 3: DS7 Start/Stop 1 ￫ 0
• Profiles 4 to 11: FaultAck = 1
• 1-0-A switch in position 0
Warnings (WARN) cannot be acknowledged, since they are simply messages
without an ensuing response (from the DS7-SWD soft starter).
The diagnostic data that corresponds to the PROFIdrive profile can be sent at
any time regardless of the profile chosen. It is provided via the acyclic
services of the relevant bus system.
