F252 Master drive encoder failure: quadrant error
A hardware error was discovered in the high resolution position interface
for "DLF" sine signals of the external measurement system.
Cause:
1. Defective encoder cable
2. Insulation distrubance on the encoder cable
3. Defective DLF plug-in card
Remedy:
For 1. Exchange the encoder cable
For 2. Separate the encoder cable from the power cables.
For 3. Exchange the DLF plug-in card
F253 Incr. encoder emulator: pulse frequency too high
Cause:
The incremental encoder emulator can process a maximum of 2047
increments per sample period 500µs; this value has been exceeded.
Remedial action:
1. Reduce the number of lines of the incremental encoder emulator
(P-0-0502).
or
2. Reduce the travel velocity.
See function description: "Activating 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 or if bit 13 = 1 in parameter P538, Motor
function parameter 1, 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. Acceleration time exceeds maximum torque greater than 1.5s.
5. Acceleration torque equals limit torque.
The error message can be switched off in the motor function parameters.
F262 External short at status outputs
Status outputs 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.
