POSICON position control for NORD frequency inverters, SK 530E and above
70 Subject to technical alterations BU 0510 GB-3911
7 Troubleshooting
7.1 Error messages
The majority of frequency inverter functions and operating data are continuously monitored and simultaneously
compared with limiting values. If a deviation is detected, the inverter reacts with a warning or an error
message.
For basic information on this topic please refer to the operating instructions BU0500.
The following table shows all the faults which are attributable to the POSICON function. In the operating
display of the optional "ControlBox" only error E013 is displayed. A finer categorisation of errors can be
obtained from the information parameters P700 "Actual Faults" or P701 "Last Fault 1...5".

Cause

Remedy
Group Details in
P700 / P701
E013 13.0 Encoder error No signal from encoder

Check 5V sensor if available.

Check supply voltage of encoder.
13.1 Speed slip error The slip speed error limit was reached.

Increase setting in P327.
13.2 Switch-off monitoring
(slip error) The slip error monitoring was triggered; the motor could not
follow the setpoint.

Check motor data P201-P209! This data is very
important for the current control

Check motor circuit.

If necessary, check the encoder setting P3xx in
Servo mode.

Increase setting value for torque limit in P112.

Increase setting value for current limit in P536.

Check braking time P103 and extend if necessary
13.5 Flying Saw acceleration The set acceleration path (P613[-63]) is too small.
13.6 Flying Saw value false The prefix of the acceleration path (P613[-63]) does not match
the prefix of the master speed
E014 14.2 Reference point error The reference point run was cancelled without a reference point
being found.

Check the reference point switch and the control unit
14.4 Absolute encoder error Absolute encoder defective or connection faulty (Error message
is only possible with positioning enabled)

Check absolute encoder and wiring

Check the parameterisation in the frequency inverter

Five seconds after switching on the frequency
inverter there is no contact with the encoder

The encoder does not respond to an SDO command
from the frequency inverter

The parameters set in the frequency inverter do not
correspond to the possibilities for the encoder (e.g.
resolution in parameter P605)

The frequency inverter does not receive a position
value over a period of 50ms
