F288 Error during firmware update of EMD Module firmware

F291 Timeout in EMD Module

DOK-ECODR3-FL*-04VRS**-FK01-EN-P
Description:
An error occurred during the Firmware update for the EMD Module. After
checking the remedy in the drive controller, clear the error and switch
from Parameter to Manual Mode again and check if the error recurs.
Cause:
•
Error while clearing the flash memory
•
Error during flash memory programming
•
Error during flash memory checksum
•
Address switch on the EMD Module is set incorrectly.
•
Communication Timeout
•
The supply voltage for the EMD Module was turned off
Remedy:
Please check the following:
1. the EcoX bus
2. the position of the address switches at the EMD module (to accept
the new address please cut off the supply voltage at the EMD module
and switch it on again)
3. the correct supply voltage of the EMD modules
Then proceed as follows:
1. Clear the error message in the drive controller.
2. Switch form phase 2 to phase 3.
3. Make a test to see whether the error is generated again. If yes, the
electronic module may be damaged and will have to be replaced.
The EMD Modules send the inputs to the base unit in a cyclic telegram. If
this telegram is not sent for 2 cycles, Error F291 is generated. The
telegram cycle time is dependent on the number of slaves on the EcoX-
Bus.
The following is valid:
Cycle Time = (Number of Slaves +1) ms.
Cause:
1. Address switch on the EMD Module is set incorrectly.
2. Faults on the EcoX Bus.
3. EcoX Bus is incorrectly wired.
4. The supply voltage for the EMD Module was turned off
Remedy:
1. Check the address switch on the EMD Module (for the new address
to be accepted, the supply voltage must be turned on and then off at
the EMD Module).
2. Check EcoX Bus
3. Check the wiring of the EcoX bus
4. Check the supply voltage for the EMD Modules.
