4.10 Diagnostic functions, fault codes and parameter list

The MICROMASTER, MICROMASTER Vector and MIDIMASTER Vector drive inverters have two alarm function stages:

Warnings and Faults.

1. Warnings

The first stage implies a warning which is output if a

drive inverter operating parameter reaches its limit

value. These parameters can include, for example,

current, voltage or temperature. When this warning is

output, the display flashes (and a bit is set in the

message which is returned via the serial interface);

however, the drive inverter is not shutdown (tripped).

The warning is automatically reset once the cause of the

warning has been removed (e.g. by reducing the load

which had caused the drive inverter to reach its current

limit).

The last warning number which was displayed is saved in

parameter P931. However, an output relay can be

parameterized using parameter P061 or P062 (not for

6SE92) so that it changes-over when a warning is output.

Alternatively, the relay can either be switched using a

warning before current limiting, voltage limiting, motor

overtemperature or slip limiting (only for 6SE32).

The warning messages can always be accessed via the

serial interface, by reading parameter P931. The warning

buffer memory can be deleted by writing 0 into it.

2. Faults

The second alarm stage is a "Fault". As soon as a fault

condition is detected, the drive inverter output is

shutdown and a flashing fault code is displayed (a bit is

set in the message which is returned via the serial

interface). The drive inverter can only be reset if the

cause of the fault has been removed. The fault can be

acknowledged by pressing the P key on the operator

panel twice, switching a digital input (if such an input was

parameterized) or via the serial interface.

The fault code, which last occurred, is saved in

parameter P930. It is possible to configure an output

relay using parameters P061 or P062 (not for 6SE92) so

that its state changes if a fault is output.

After a fault code has been acknowledged, the drive

inverter changes into a power-on inhibit status. The drive

inverter must then be actively powered-down (using the

keypad, digital input or serial interface, depending on

which control technique was configured) before it can be

powered-up again. This can be de-activated by setting

parameter P081; in this case, the drive inverter attempts

a restart as soon as the fault has been acknowledged.

The fault buffer memory can be deleted by writing 0 into

it. In the case of 6SE32, parameters P140, P141, P142

and P143 contain the last as well as the second from last,

third from last and fourth from last faults.
