Invalid sources

The following DRIVE-CLiQ communication failures do not produce an ESR trigger:
1. Pulse suppression of the Motor Modules is pending
2. Failure of encoder modules as motor measuring system
3. Failure of encoder modules as a direct application-specific measuring system
7.12.5 ESR responses
7.12.5.1 Extended stopping
In the case of a fault, the objective is to stop the drive in a defined fashion. The stopping
method is used as long as the drive is still capable of functioning. The function is
parameterized and operates on an axis-specific basis. Axes are not coupled.
Configuring the "extended stop" response
1. The stop response is configured with p0888 = 1.
2. Using p0892, the time is set for which the last setpoint from r1438 is frozen before
3. The OFF ramp is selected using p0891.
418
– The drive performs an OFF2 and coasts to a standstill.
– The system is switched over to operation without encoder and a parameterized stop
reaction is initiated.
– The application is deactivated and a parameterized stop reaction initiated.
braking is initiated.
