PTC Short Circuit
Description
External PTC resistor short circuit.
Event
Detected the short circuit of the PTC connected to
AIN2
input (R < 10 ohm).
Possible cause
•
Short circuit in the PTC.
•
Incorrect wiring of PTC.
•
Incorrect setting of
SW1
hardware switch on the control board.
Solution
1. Make sure that the PTC is correctly connected to
AIN2
analog input (for further detail,
please contact ENERTRONICA SANTERNO
’s Customer Service).
2. Make sure that
SW1
hardware switch is correctly set..
A057

Event
The drive has detected a parameter configuration error.
Possible cause
Wrong settings.
Solution
Check settings and enter correct settings.

Serial Link Watchdog
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.
This alarm does not trip if, due to parameters in the Control Method Menu
– section 2.6.6, or due
to the status of the source selection or LOC/REM inputs (Digital Input 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
Description
Mains loss.
Event
Mains loss (only if AC power supply is available and parameter
C802
= 1: Yes).
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 alarm can be disabled by means of parameter
C802
(see section 2.6.9).
