MOTOR PTC
ERROR
Motor PTC temperature
monitoring error
1- The motor PTC temperature function
is activated, so check the connection of
PTC/thermostat circuit made to PI2 input
on ENCABIT-Plus module.
2- Motor PTC circuit may be interrupted.
28
Imax TRIP LIMIT
The motor current exceeds the
value set in parameter 11.10
during the period of time set
in parameter 11.11
1- Ensure that the parameters are correctly set.
2- There may be a mechanical strain in the motor.
3- Check that the mechanical brake is opening
and closing correctly.
29
LOW BATTERY
The required power for
driving the motor cannot
be taken from the battery
set.
1- Ensure that the connected battery set
has suitable voltage (60V) and capacity
(7Ah).
2- The batteries may be discharged. Keep
the batteries on charge.
30
RESITOR OVER
RUN
The braking resistor has
been used very
intensively. It is under
dangerous overheat
conditions.
Braking resistor’s resistance may be
incorrect. Be sure that the braking resistor
is suitable for Inverter's power and motor
power.
31
LOW CPU SUPPLY
The CPU supply is low.
(Only in ADrive Size-D)
1- The value of 3 phase AC supply may have
fallen below 340 V. Check the voltage of the
terminals in L1, L2 and L3.
2- If the device is being supplied from an external
24 VDC source, check the voltage of this external
source.
3- If the circuit voltages are all normal, unplug the
device and contact ARKEL technical support.
