Troubleshooting procedure
Proceed with care during troubleshooting and error rectification to avoid damaging the
controller.
Danger of electrical surges
An operating voltage > 50 V and incorrect connections can destroy the end stage.
Never disconnect the link when operating voltage is applied!
Never disconnect lines when live!

Rectification
Controller is
not ready
Data transmission to SMCI33
not possible (communication
error):
Incorrect COM port selected.
In the "Communication" tab, select
the PC port to which you have
connected the SMCI33 (e.g." COM-
1")
The port used can be found in the
device manager of your PC.
The communication cable is not
connected or is interrupted.
Use only the recommended
converter from Nanotec:
•
ZK-RS485-RS232
•
ZK-RS485-USB
A non-existent motor number
(module number) is set.
Set the correct module address.
See the separate manual on
NanoPro.
The power supply of the SMCI33
is interrupted.
Check voltage supply, switch on if
necessary.
Another open program is
blocking the COM port to which
the SMCI33 is connected.
Close down other programs on your
PC.
Inadmissible data was sent to
the controller during the output
of a travel profile.
Click on the <Yes> button to stop the
travel profile.
The SMCI33 switches back to the
"Ready" state. The data can then be
resent to the controller.
Transmission
error
Data transmission to the
SMCI33 is disturbed (sender or
receiver are disturbed).
Check that the motor connection is
correctly wired.
We recommend using the following
Nanotec converters:
•
ZK-RS485-RS232
•
ZK-RS485-USB
Position error The motor cannot reach the
position or the limit switch was
overrun.
Click the <Yes> button in the error
message; the error is reset.
Red LED on
the SMCI33
lit up.
Overtemperature of power
electronics > 75 °C
Switch off controller and allow to
cool.
The error is reset when the SMCI33
is disconnected from the power
supply unit.
Undervoltage
Check voltage supply.
