The error detected in FOC control by the current loop exceeds the max. allowable
value.
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
REGULATORS MENU
). Perform a new current regulator autotune (see
AUTOTUNE MENU).

A062 (Serial
Description
A061: Serial Link Watchdog 0 tripped
A062: Serial Link Watchdog 1 tripped
Event
The serial link watchdog has tripped.
Communication failur
e: 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
LINKS MENU).
This alarm does not trip if, due to parameters in the CONTROL METHOD MENU
due to the status of the source selection or LOC/REM 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
2. Make sure that the remote master constantly sends read/write queries w
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
A064 Mains Loss
A064 Description
Mains loss
Possible
cause
• One supply cable is disconnected.
• Mains supply too weak.
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).
