A052 Illegal XMDI in DGO
A052 Description Illegal configuration of XMDI in the Digital Outputs menu.
Event
• The drive checked if at least one XMDI input from ES847 or ES870 I/O
optional board is available in the DIGITAL INPUTS MENU;
• The drive checked if R023
(I/O Board setting) is set to 0 in the
EXPANSION BOARD CONFIGURATION MENU
Wrong settings.
Check settings and enter correct settings.
A053 Not PWONA
Hardware failure; IGBT A power on failure.
IGBT A power on controlled by Motorola microcontroller has failed.
Control board failure.
Solution
1. Reset the alarm: send a RESET command.
2. If the alarm persists, please contact ELETTRONICA SANTERNO’s Customer
A054 Optional Board not in
A054 Description ES847 or ES870 not in.
Event
The control board detects no ES847 or ES870 I/O expansion boards after
parameter R023 (I/O Board Setting) is set as ≠ 0.
Optional board not in or faulty.
Solution
1. Check consistency of parameter R023 (see the EXPANSION BOARD
CONFIGURATION MENU).
2. Reset the alarm: send a RESET command.

A055 PTC Alarm
A055 Description External PTC resistor tripped.
Event
The drive detected the opening of the PTC connected to AIN2 input (R > 3600
ohm)
Possible
cause
• Opening of the PTC due to motor overheating.
• Incorrect wiring of PTC.
• Incorrect setting of SW1 hardware switch on the control board (see Installation
Solution
1. Allow the motor to cool, then reset the alarm.
2. Make sure that the PTC is correctly connected to AIN2 analog input (see
Installation Guide).
3. Make sure that SW1 hardware switch is correctly set.
