9095 0x2387 Imax: Clamp responded too oen Keypad display: Clamp meout
Cause Error type/response Remedy
Maximum current of the axis (display in
0x2DDF:002) has been reached too oen in suc-
cession.
Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
Select a aer speed ramp.
•
Reduce the load.
•
Set Imax controller more dynamically.

9096 0x2388 SLPSM stall detecon acve Keypad display: SLPSM stall det.
Cause Error type/response Remedy
Overload of the motor with sensorless control
for synchronous motors (SL-PSM).
Trouble
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
Reduce load at the axis.
•
Check sengs of the SL-PSM parameters.

12576 0x3120 Mains phase fault Keypad display: Mains Phase fail
Cause Error type/response Remedy
Mains phase failure Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
Check wiring of the mains connecon.
•
Check fuses.
12672 0x3180 Operaon at UPS acve Keypad display: UPS oper. acve
Cause Error type/response Remedy
Operaon on uninterrupted 1x230V current
supply (UPS) has been acvated: Only a
reduced output current is provided.
Warning Switch back to operaon with regular mains
voltage.

12816 0x3210 DC bus overvoltage Keypad display: DC Bus OV
Cause Error type/response Remedy
DC-bus voltage has exceeded the error thresh-
old for overvoltage due to a too high braking
energy or a too high mains voltage. The error
threshold (display in 0x2540:006 (P208.06))
results from the seng of the rated mains volt-
age in 0x2540:001 (P208.01).
Fault
•
The inverter is inhibited immediately. The
motor becomes torqueless (coasts).
•
Reduce dynamic performance of the load
prole.
•
Check mains voltage.
•
Check sengs for the brake energy manage-
ment.
•
Connect brake resistor to the power unit and
acvate the integrated brake chopper.
