F828 Safe Halt while drive activated
When the digital input is selected while the drive is activated, the "F828
Safe Halt while drive activated" error message is output. The drive is
currentless in any case.
F842 Encoder 2 failure: signal amplitude wrong
Cause:
Same cause as for error F242 Encoder 2 failure: signal amplitude
wrong. Encoder 2, however, is required for velocity control by means of
the velocity mix factor. It is therefore impossible to shut the drive down in
a controlled way when this encoder fails.
F845 Encoder 2 failure: quadrant error
Cause:
Same cause as for error F245 Encoder 2 failure: quadrant error.
Encoder 2, however, is required for velocity control by means of the
velocity mix factor. It is therefore impossible to shut the drive down in a
controlled way when this encoder fails.
F860 Overcurrent: short in power stage
The transistor (IGBT) current has exceeded the allowed maximum peak
value. The drive is immediately disabled, the motor freewheels to a stop.
Cause:
1. Short circuit in the motor or motor cable.
2. Defective power section of the drive controller
3. The current regulator was parameterized with wrong values.
Remedy:
For 1. Check the motor cable for a short.
For 2. Exchange the drive controller.
For 3. Check that the current controller parameters are as given in the
motor data sheet; if they differ, input the correct values.
F870 +24Volt DC error
The drive controller requires a 24V control voltage. The drive’s torque is
released immediately when the maximum permissible tolerance of
+-20 % is exceeded. If an optional electrically released motor holding
brake is present, then it is activated.
Cause:
1. Defective cable for the control voltages.
2. 24V power supply overload.
3. Defective power supply unit.
4. Short-circuit in the emergency stop circuit.
