Siemens A01940 fault code meaning
Siemens / A01940
Series: DCM-6RA80
PB/PN: Isochronous synchronization not achieved
DC drive
Meaning: The bus is in the data exchange state (Data Exchange), and isochronous synchronization has been selected via the configuration telegram, but synchronization with the cycle specified by the master is still not possible. - Although isochronous mode has been selected in the bus configuration, the master does not send an isochronous global control telegram. - The master uses a different isochronous DP cycle from the cycle in the configuration telegram transmitted to the slave. - At least one drive object has pulse enable (not controlled via PROFIBUS-/PROFINET).
Possible causes

PN: Isochronous synchronization not achieved
converter
Meaning: The bus is in the data exchange status (Data Exchange), and isochronous synchronization has been selected via the configuration telegram, but synchronization cannot be performed at the cycle specified by the controller. - Although isochronous run has been selected in the bus configuration, the controller is not sending isochronous telegrams. - The controller uses a different isochronous bus cycle from the cycle used to transmit the configuration telegram to the device.
