3.2 Problem solving
SOLUTION FOR ALARM 1
(
EEPROM
):
● With the software interface try to save the parameters to the drive's EEPROM, then power off and
on the drive, if the Alarm 1 appears then contact for assistance;
SOLUTION FOR ALARM 2
(
Overcurrent
):
● Power off the drive;
● Verify if the motor wire connection is correct (
see cap. 2.10 Motor Power connection on page 38
)
.
● If the connection are correct, check if there are any type of faulty wiring that can cause any type
of short circuit:
+AT
-AT
U
V
W
WRONG
+AT
-AT
U

CORRECT
● If there aren't any faulty cable, disconnect only the motor phases ( Brushless: U/V/W, DC: +M/-
M, Stepper: +A/-A/+B/-B ), leave the feedback connected, power up the drive and set it with the
OP Mode: Digital speed (
see cap. 4.3 Digital Speed on page 67
) and with Speed 100 RPM, enable
the drive. If the Alarm 2 appears then contact for assistance, if not that means the drive don't have
the problem, continue on the next point.
● If there are an extension cable between the motor and the drive then:
- If you have a replacement, try to replace it with an equal cable.
- If you don't have a replacement, disconnect the cable form the motor and the drive, with a
multimeter or multitester, check if there any short circuit between two wire of the cable. Check if
there are wire's isolation damaged that can create any type of short circuit, because all the wire
must be isolate form each-others, if there are any damaged or short circuit then replace the cable.
Connect the cable between the drive and the motor, and try to enable the drive. If the Alarm 2
appears then continue on the next point.
● If you have a replacement motor, then replace it with an equal motor (a working one) and try
to enable the drive, if the Alarm 2 appears then contact for assistance, if it not appears then that
means the replaced motor have a problem.
SOLUTION FOR ALARM 3
(
Drive Temperature
):
● Verify the ambient temperature around the drive.
● Verify the heat dissipating power of the heat-sink where is mounted the drive.
● Verify if there are enough airflow in the cabinet that remove the hot air.
● Wait until the radiator has cooled off, the alarm will auto-reset when the temperature drop under
90°C, then enable the drive.
SOLUTION FOR ALARM 4
(
Hall
):
● Verify the cell's wire connection and feedback setting (
see cap. 2.11 Motor Feedback connections
), reset the alarm, then enable the drive.
