Trouble Shooting - piezosystemjena NV40/3 Bedienungsanleitung

9 trouble shooting

During operation the display can show a defined error code. A reason can be the buffer
overflowing, a temperature value out of range or a overshooting of the actuating system. Promptly
the error code is provided on the display and on the connected PC too. The code is 16bit wide and
it's binary-coded (ERROR,FWch0,FWch1,FWch2). The code is based on follow:
bit
0
1
12
13
14
15
2,3,4,5,6,7,8,9,10,11 not used
Some possible errors and their corrections are listed in the following table:

possible error correction
Please check the main voltage supply and all connections. Please
check the position of the main power switch on the back side. Please
check if the main power module pluged in (indicated by a LED)
Please check if the actuator is pluged in and the connector fixed by
the screws correctly. Please check all cables and connectors for any
damage.
Check the value oft he Offset. High modulating voltage overdrives the
amplifier. Switch off the modulation or reduce the modulation voltage
until sign is off.
Buffer overflow: please check the status of the actuating system. The
system must be able to move over the entire travel range without
limitation. Also an mechanically overloaded system can cause this
error code. For more information about the may. load, please check
the calibration information provided with the actuating system.
The resonant mode of actuating system is reached. The calibration
datas needs to be adjusted according to the load or control function.
Reducing of the applied load.
