Removing the Battery
•
Unscrew torx screws with size 10 screwdriver.
•
Pull out the resolver feedback (RSF) lid by hand.
•
Pull off the battery connector.
•
Loosen battery clamp and remove the battery.
•
Place the prepared battery in the housing and screw on the clamp.
Attention! Do not kink or clamp the battery cable.
•
Attach the connector of the battery.
Close the resolver feedback lid, screw in 4 torx screws and tighten to 1.8
Nm with the torque wrench.
F253 Incr. encoder emulator: pulse frequency too high
Cause:
The incremental encoder emulator can process a maximum of 2047 lines
per sample period (500µs ); this value has been exceeded.
Remedy:
1. Reduce the number of lines of the incremental encoder
emulator (P-0-0502).
or
2. Reduce the travel velocity.
See also the functional description: "Encoder Emulation".
F260 Command current limit shutoff
If the current setpoint reaches the peak value, then warning E260
Command current limit shutoff is generated. If the limit remains
standing for more than 1.5 ms, then the drive is shutdown with error
message F260 Command current limit shutoff.
Error cause:
1. Motor power cable has not been connected.
2. Motor holding brake not released (not connected).
3. The axis is mechanically jammed.
4. Accel time exceeds maximum torque greater than 1.5s.
The error message can be switched off in the motor function parameters.
F262 External short at status outputs
Status outputs (ready, warning and UD-message) are monitored for short
circuits and thermal overload.
•
If output current exceeds 350mA for about 1µs, then this is
acknowledged as a short circuit and the pertinent channel is shut off.
The output remains off unit the error is cleared.
