7.2.11 Predictable User Errors
The following list shows predictable user errors an the measures taken:
User Error
Measures, Description
Wrong firmware loaded to drive.
As described in 9.2 - FW Installation, only approved firmware versions are allowed to use. The
correct firmware installation must be checked by comparing the CRC.
Inconsistent Configuration
When writing the safety configuration to the drive, a consistency check is done. Especially the
combination of safe encoder type and configured safety functions, based on a safe position
encoder, are checked. In case of an inconsistency the error "Send data failed: Parameter
Error" is generated.
Parameter Out of Range
All parameters are checked for the allowed range. In case of a range violation, LinMot-Talk will
block and the safety software on the drive checks the ranges as well. In case of an error, the
message "Send data failed: Parameter error" is generated.
Motor or Encoder not correctly connected The safe position encoder is permanently checked by orbit and cross monitoring.
No safety Encoder connected
The communication to the motor is permanently running. The motor temperature is cyclically
read and the checksum and life signal are checked.
Slider mission
The orbit monitoring will generate an error, due to wrong encoder signals.
Slider mounted in wrong direction
LinMot-Talk provides a motor wizard for the motor configuration. It guides the user graphically
step by step through the configuration.
No safety slider
Compatibility listed in 6.2 - Motors
Wiring fault on Safe Dig In
Consistency check is done on drive. Stuck at must be detected on the output module. See also
7.2.8 - Periodic Proof Tests
Wiring fault on Safe Dig Out
Checked periodically with test pulses. See also 7.13 - Safe Digital Output
Brake not connected
SBC checks by measuring the current if the brake is connected.
Brake test with too small current
The user must check during SBT verification, that the demand current for the requested force is
driven. See 7.17.4 - Verification and Validation
SBT with no brake configured
If the SBT is started when no brake (neither safe nor non-safe) is configured, the drive will
report a brake test failure.
