E-OC
Current overload
0
Current overload due to:
1. Incorrect parameter setting
2. Short, earth fault or insulation fault
3. Internal device defect
Remedy:
1. Check parameters of control circuits
2. Check installation
1
Ixt-shut-off below 5 Hz to protect power stage.
Reduce load
43
Power stage protection initiated, maximum allo-
wed motor power exceeded. The value depends
on DC-link voltage and heat sink temperature.
1. Check operating conditions of device
2. Reduce load
46
Current overload shut-off after wiring test.Detec-
ted short, earth fault or insulation fault.
1. Check installation
2. Check motor insulation
48
Current overload detected
1. Adverse parameter adjustment
2. Short circuit, earth fault or bad isolation in active
state
3. Internal device error
Remedy:
1. Check parameter adjustment of control circuit
2. Check installation
3. Please contact your service provider if this error
occurs again
49
Same as above
50
Internal error while current overload monitoring
1. Switch off/on device
2. Please contact your service provider if this error
occurs again

E-OV
Voltage overload
1
Voltage overload due to:
1. Braking chopper overload (braked too long or too
much)
2. Mains poer overload
Remedy:
1. Set DECR ramp parameter lower, use ext. braking
resistor or chopper
2. Adjust mains voltage
E-OLM
Motor overload
47
Ixt-shut-off to protect motor (permissible current/time
area exceeded)
1. Check parameter setting of motor protection
2. Reduce load
3. Use higher-powered motor
E-OLI
Driver overload
48
I^2xt-shut-off to protect power stage (permissible cur-
rent/time area exceeded)
1. Reduce load
2. Use higher-powered motor
E-OTM
Overheating motor
46
Short circuit in motor temperature PTC
1. Check cabling of motor PTC
47
Overheating motor (PTC in motor tripped) due to:
1. Temperature sensor not connected or incorrect para-
meter setting
2. Overload of motor
Remedy:
1. Allow motor to cool down
2. Connect temperature sensor or check adjustment
3. Use a higher-powered motor
