Serious Condition
E1
The external pulse encoder e.g. IPG... is defective or not connected
E2
Line voltage too low, or time between power Off and power On too short
E3
Machine blocked or does not reach the desired speed
E4
Control disturbed by deficient grounding or loose contact
E5
Motor end level over-temperature
E7
24 V power supply unit overload
E8
Too much data for the EEPROM or flash memory
E9
EEPROM or flash memory defective.
E10
End phase transistor short circuit(Output FL, VR, M1, M2, M3, oder M4)
E11
Thermal overload of output stage transistor
E12
Short-circuit on output M5
E13
Thread trimmer does not reach the end position
E14
Power voltage too high: The power voltage is greater than 290 V eff.
(The DC motor cannot be started; if running, the motor is stopped without
positioning. The motor is passively braked (runs down)!
E15
Internal communications error with intermediate circuit
E16
Power voltage too low: The power feed voltage was less than 120 V eff.
(The DC motor cannot be started, and the 24 V is turned off.)
E17
Charging PTC too warm. The intermediate circuit could not be charged to
the voltage needed.
Possible cause: Switching the controller on/off to many times within a short
time.
Correction: Turn off controller and allow it to cool. (The duration of the
cooling off phase depends on the ambient conditions and can take several
minutes).
E18
Intermediate circuit voltage greater than 450 V, braking resistance possibly
failed
E19
No motor connected, inverter defective, motor phase failed
E20
Speed too high
E21
Error in the 5 V power supply
E22
EB401: Analog value outside the range
E23
V860: Error during communication
E24
Customer null point sensor not detected
E25
IGM/HSM not detected
Programming and Data Transfer
F1
Parameter unavailable; wrong code number
F7
RS232 Time out
F8
RS232, error in data transfer, NAK received
Hardware Disturbance
H1
Commutation transmitter cord or frequency converter disturbed
H2
Processor disturbed
Status messages
WAIT
Cause: No control software loaded.
Solution 1: Software must be loaded with IF232 cable.
PROG
Cause: Controls updates the intermediate circuit processor. If no software
update can be executed, this could also be an error of processor
communication. Then the message appears every time it is switched on.
Solution 1: Software must be loaded with IF232 cable.
Solution 2: The controls must be sent in for repair.
