SOLUTION FOR ALARM 5
(
Encoder
):
● Verify the wire connection and feedback setting (
see cap. 2.11 Motor Feedback connections on
), reset the alarm, then enable the drive.
SOLUTION FOR ALARM 6
(
I2t Drive
):
● Disable the drive.
● The cause could be one of the following:
• The working cycle could be too heavy;
• A possible mechanical block / degradation or the some mechanical parts need of lubrication;
• A motor phase inversion;
• Incorrect motor phase angle;
• The amplifier's dynamic costants: "KP", "KI" and "KD", could create useless current oscillation.
● Try running the motor with digital reference in OP Mode 10: Square Wave Period, be aware of the
mechanical movement;
SOLUTION FOR ALARM 7
(
Motor Temperature
):
● Verify
the motor case temperature.
● Decrease the dynamic constant if the motor is vibrating. This situation causes current oscillation
and consequently the overheating of the motor.
● Wait until the motor has cooled off, reset the alarm, then enable the drive.
SOLUTION FOR ALARM 8
(
Regenerative Resistance
):
● Verify the resistor setting in the software interface.
● Verify the resistor connection.
● Verify that the working cycles are not excessive.
● Verify if the motor, going at half speed, shows the same problem.
● Reset the alarm, then enable the system.
SOLUTION FOR ALARM 9
(
Min Voltage
):
● Disable the drive.
● Verify the power supply connection on the drive (
see cap. 2.8 Power supply connections on page 33
).
● Verify the voltage level on the power input (
see cap. 1.3 Technical Data on page 11
).
● Verify the output voltage stability of the power supply, even during the working cycles.
SOLUTION FOR ALARM 10
(
Pre-Alarm Recovery
):
● This alarm will auto-reset when the I2t energy recovery drop under 80%.
SOLUTION FOR ALARM 11
(
USB Mack-Link
):
● Verify if the ground and earth connection are performed as showed in basic installation procedure
(
see cap. 2.5 Basic installation on page 28).
● Replace the USB cable if is damaged or is not shielded (
see cap. 2.3 Cables characteristics on page 25
SOLUTION FOR ALARM 13
(
Overvoltage
):
● Verify the power supply connection on the drive (
see cap. 2.8 Power supply connections on page 33
).
● Verify the voltage level on the power input (
see cap. 1.3 Technical Data on page 11
).
● When the input voltage level on power supply and connection are correct then the alarm will auto-reset.
● Verify that the working cycles are not excessive, if the problem appears during the running
operation and there is not present any braking resistor maybe is necessary to install one (
cap. 2.9 Regen resistance connections on page 36
SOLUTION FOR ALARM 14
(
Following Error
):
● Verify if the connection are correct.
● Verify if there are any mechanical block.
● With the software interface check:
• The Max Position Error parameter and the dynamic gains under Position Loop;
