A060 No Current Fault (FOC)
A060
Description
The error detected in FOC control by the current loop exceeds the max. allowable
value.
Event
The FOC control detected a current regulation error.
Possible
cause
•
One motor cable is disconnected.
•
Failure in the current measure circuit.
•
Wrong setting of current regulator parameters for FOC control.
Solution
1. Check motor connections (terminals
U, V, W
).
2. Check parameterization of current regulators for FOC control (see the FOC
REGULATORS MENU). Perform a new current regulator autotune (see
AUTOTUNE MENU).
3. If the alarm persists, please contact ELETTRONICA SANTERNO’s Customer
Service.
A061, A062 Serial Link Watchdog
A061 (Serial
Link 0)
A062 (Serial
Link 1)
Description
A061
: Serial Link Watchdog 0 tripped
A062
: Serial Link Watchdog 1 tripped
Event
The serial link watchdog has tripped.
Communication failure: no read/write query sent to serial link for a time longer than
the time set in the parameters relating to serial link watchdog (see the SERIAL
LINKS MENU).
This alarm does not trip if, due to parameters in the CONTROL METHOD MENU or
due to the status of the source selection or LOC/REM inputs (DIGITAL INPUTS
MENU), the information sent from serial link is not currently used for the commands
or the references.
Possible
cause
•
Serial link is disconnected.
•
Communication failure on remote master side.
•
Watchdog operating times too short.
Solution
1. Check serial link.
2. Make sure that the remote master constantly sends read/write queries with max.
intervals between two queries lower than the preset watchdog operating time.
3. Set longer watchdog operating times (see
R005
for serial link 0 and
R012
for
serial link 1).
A064 Mains Loss
A064
Description
Mains loss
Event
Mains loss.
Possible
cause
•
One supply cable is disconnected.
•
Mains supply too weak.
•
Mains gap.
Solution
1. Check voltage in terminals
R
,
S
,
T
. Check mains voltage value
M030
. Also
check the value of
M030
sampled in the
FAULT LIST
when
the alarm tripped.
2. This protection may be disabled or delayed (see the POWER DOWN MENU).
