The Milan drive advanced is equipped with extensive monitoring functions and status signals.
Basically, faults are distinguished by an immediate shut-down of the drive and warnings, that merely generate a signal.
If the control is operated via Profibus DP or CAN-Open, all faults and warning signals can be transmitted separately.
The warning is often considered as a preliminary stage of a fault.
If, e.g. the motor temperature rises over 130 °C, a warning signal is generated. Upon exceeding 140 °C, the drive is switched off.
- DC-link circuit lower than 220 V
- Brake voltage lower than 22 V or higher than 26 V
- Motor temperature higher than 130 ºC
- Electronic temperature higher than 70 ºC
- Contouring error
- Derating
The immediate switch off in the event of a fault prevents the Milan drive advanced from being damaged.
The various diagnosis possibilities allow a quick location and elimination of the fault.
- DC-link circuit lower than 180 V or higher than 400 V
- Brake voltage lower than 20 V or higher than 28 V
- Motor temperature higher than 140 ºC
- Electronics temperature higher than 75 ºC
- Quickstop command is available
- Drive blocked
