NOTE
When a malfunction occurs, it isn’t always obvious if the
problem is mechanical or electrical. For example, for a given
fault (for example; cylinder doesn’t move), the root cause may be
mechanical (for example; motor brake blocked) or electrical (for
example: electrical power not validated in the servoamplifier).
Consequently, in case of malfunction, please consider all
possible causes (mechanical and electrical) to identify all
possible solutions.
6.1 Mechanical
malfunctions
Malfunction
Possible cause(s)
Possible solution(s)
Cylinder doesn’t move
Motor brake blocked
Check brake connection and supply voltage
System moved by cylinder blocked
Check mobility of system moved by cylinder
Cylinder uses a lot of
current and/or makes
a noise when moving
Motor brake blocked
Check brake connection and supply voltage
System moved by cylinder blocked
Check mobility of system moved by cylinder
Cylinder is too hot
Overloading
Measure RMS torque value on one complete cycle (including
pause time before starting a new cycle). Send this information
to Ewellix for analysis.
Ambient temperature too high
Comply with permitted temperature range
