Activating and enabling the ESR function module

PG/PC and drive are connected with one another via PROFIBUS or PROFINET.

1. Select the ESR function with parameter p0888:

– p0888 = 0: No function

– p0888 = 1: Extended stopping (function integrated in the drive), N-set

– p0888 = 2: Extended retraction (function integrated in the drive)

– p0888 = 3: Generator operation (Vdc controller)

– p0888 = 4: Extended stopping (function integrated in the drive), N-actual

2. Enable the ESR response with p0889 = 1.

3. Transfer the settings to the Control Unit using the "RAM to ROM" function.

The parameterization of p0888 can be changed from a higher-level control depending on the

particular situation - as long as the ESR response is not yet enabled.

You can also activate function modules in STARTER under "Configuration" > "Function

modules / technology packages".

You can check the current configuration in parameter r0108.9.

Checking the ESR status

The current ESR status can be checked with the aid of parameter r0887.0...13.

Axis-related trigger sources

Conditions for triggering the function:

● ESR function has been configured in the drive with p0888, e.g. stopping or retraction.

● ESR function has been enabled in the drive with p0889 = 1.

● The pulse enable has been set.

A distinction is made between the following fault sources:

● Internal drive fault

– Faults with reactions OFF1 or OFF3

– p0840 (On/OFF1) and p0849 (OFF3) wired to terminal

● Internal trigger signal

– The source for the ESR trigger signal is set via BICO using p0890.
