A100 Mains Frequency KO
A100
Description
The mains frequency is not included in the range set by the values
in the MAINS MONITOR MENU.
Event
Strong variations of the mains frequency.
Possible
causes
Voltage dips during the drive operation.
Solutions
1. Check the value of the mains frequency measured in
M504.
2. Also check the values of this measure, that are sampled in the
FAULT LIST
in the instant when the protection tripped.
3. This protection can be disabled or delayed (see the MAINS
MONITOR MENU).
A101 Min. Mains Voltage Supply
A101
Description
The characteristic of the mains voltage is under the tolerance set by
the values in the MAINS MONITOR MENU.
Event
Power supply loss.
Possible
causes
A feeder cable has disconnected.
The mains supply is too low.
A voltage dip has occurred.
Solutions
1. Check the correct voltage value in the 3 phases (terminals
R
,
S
,
T
).
2. Check the value of the mains voltage measured in
M502.
3. Also check the values of this measure, that are sampled in the
FAULT LIST
in the instant when the protection tripped.
4. This protection can be disabled or delayed (see the MAINS
MONITOR MENU).
A102 Max. Mains Voltage Supply
A102
Description
The characteristic of the mains voltage is above the tolerance set by
the values in the MAINS MONITOR MENU.
Event
Strong variations of the mains voltage.
Possible
causes
The mains supply is too high.
Solutions
1. Check the correct voltage value in the 3 phases (terminals
R
,
S
,
T
).
2. Check the value of the mains voltage measured in
M502
.
3. Also check the values of this measure, that are sampled in the
FAULT LIST
