ECODRIVE03-FL*-04VRS
F253 Incr. encoder emulator: Frequency too high
F267 Erroneous internal hardware synchronization
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
Malfunction in the control of motors and moving
elements
Equipment damage can occur.
Turn off the power supply. Make sure the equipment is
CAUTION
not switched back on. Replace the battery while the
control voltage is turned on.
If the control voltage is turned off while the battery is out, the absolute
reference point will be lost. Then, the reference point must be
reestablished using the "Set absolute encoder" command.
Removing the Battery
Unscrew Torx screws (1) using size 10 screwdriver.
Pull out the resolver feedback (RSF) lid by hand.
Remove battery connector (2)
Undo battery clamp (3) and remove battery
Place the battery pack in the housing and screw on the clamp. Attention!
Do not kink or crimp the battery cable.
Attach battery connector (2)
Close the resolver feedback lid, screw in the 4 Torx screws (1) and
tighten to 1.8 Nm with the torque wrench.
Cause:
The incremental encoder emulator can process a maximum of 1023
graduation marks per 250-µs sampling period; this value was exceeded.
Remedy:
1.
Decrease the number of lines to be used by the incremental
encoder emulator (Parameter C015).
or
2.
Reduce the travel velocity.
See also functional description for: "Encoder emulation."
Cause:
The drive control is synchronized to the bus interface (DIO, Profibus).
Synchronization is monitored to check for proper functioning. If the
average value of the deviation exceeds 5 µs, this error message is
generated.
Remedy:
Replace the drive controller.
