Table21: Trouble-shooting
A B C D E F G H I Possible cause Remedy
- ✘ - - - - ✘ - - No voltage Check the mains voltage; check the mains fuses.
- ✘ - - - - - - - No enable Check enable via DIGIN-EN and system start.
✘ - - - - - - - - Mains fuse rating too small for
frequency inverter input
current
Check design configuration of mains fuse.
- - - ✘ - - - - - No setpoint signal or setpoint
set too low / drive overloaded
and in i²t control mode
Check setpoint signal and operating point.
- - - - ✘ - - - - Process-related persistent
control deviation (actual value
smaller than setpoint) / no
actual value (e.g. due to
broken wire)
Check setpoint/actual value signal; check operating
point; check controller setting.
- ✘ -
-
- - - - - ✘ Permissible voltage range
undershot/exceeded
Check mains voltage; supply frequency inverter with
required voltage.
- - - - - - - ✘ - Wrong direction of rotation
setting
Change the direction of rotation.
- - ✘ ✘ - - - - ✘ Frequency inverter overloaded Reduce the power input by lowering the speed;
check the motor/pump for blockages.
- ✘ - - - - - - ✘ Short circuit in control cable/
pump blocked
Check/replace control cable connections. Remove the
blockage manually.
- - ✘ ✘ - - - - ✘ Temperature of power
electronics or motor winding
too high
Reduce the ambient temperature by improving
ventilation.
Improve cooling by cleaning the cooling fins.
Ensure the intake opening for the motor fans is not
blocked.
Ensure that the motor fans are working properly.
Reduce the power input by changing the operating
point (system-specific).
Check the permissible load and, if necessary, use
external cooling.
- - - - - - ✘ - ✘ 24 V supply overloaded Disconnect PumpDrive from the power supply and
eliminate the cause of the overload.
- - - - - - - - ✘ Dry running of pump Check the hydraulic system and rectify the fault on
PumpDrive.
- - - ✘ - ✘ - - ✘ Sensor signal error (e.g.
broken wire)
Check sensor and sensor cable.
- ✘ ✘ - - - - - ✘ Phase failure, drive side Check motor connection and motor winding.
