17 Internal memory fault Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your Fenner authorised distributor
-20f
18 4-20mA signal lost The reference signal on Analog Input 1 or 2 (Terminals 6 or 10) has dropped below the minimum
threshold of 3mA. Check the signal source and wiring to the drive terminals.

21 Motor PTC Over temperature The connected motor PTC device has caused the drive to trip
fan-f
22 Cooling fan fault Check and if necessary, replace the drive internal cooling fan
0-heat
23 Ambient temperature too high The measured temperature around the drive is above the operating limit of the drive.
Ensure the drive internal cooling fan is operating
Ensure that the required space around the drive as shown in sections 0 and 3.8 has been
observed, and that the cooling airflow path to and from the drive is not restricted
Increase the cooling airflow to the drive
Reduce the effective switching frequency setting in parameter P2-24
Reduce the load on the motor / drive
0-tor9
24 Maximum torque limit The output torque limit has exceeded the drive capacity or trip threshold
Reduce the motor load, or increase the acceleration time
u-tor9
25 Output torque too low Active only when hoist brake control is enabled P2-18 = 8. The torque developed prior to releas-
ing the motor holding brake is below the preset threshold. Contact your local Fenner authorised
distributor for further information on using the Fenner QD:Neo in hoist applications.

atf-01
40 Autotune failed Measured motor stator resistance varies between phases. Ensure the motor is correctly con-
nected and free from faults. Check the windings for correct resistance and balance.
atf-02
41 Measured motor stator resistance is too large. Ensure the motor is correctly connected and free
from faults. Check that the power rating corresponds to the power rating of the connected drive.
atf-03
42 Measured motor inductance is too low. Ensure the motor is correctly connected and free from
faults.
atf-0
43 Measured motor inductance is too large. Ensure the motor is correctly connected and free from
faults. Check that the power rating corresponds to the power rating of the connected drive
atf-05
44 Measured motor parameters are not convergent. Ensure the motor is correctly connected and
free from faults. Check that the power rating corresponds to the power rating of the connected
drive.

50 Modbus comms fault A valid Modbus telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating
Check the connection cables
Increase the value of P5-06 to a suitable level
sc-t02
51 CAN open comms trip A valid CAN open telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating
Check the connection cables
Increase the value of P5-06 to a suitable level
