Troubleshooting procedure
Proceed with care during troubleshooting and error rectification to avoid damaging the
controller.
Danger of electrical overvoltage
An operating voltage > 75 V and swapping of the connections can destroy the
output stage.
Never disconnect the motor while operating voltage is applied!
Never hot-unplug lines.
Possible errors in serial mode

cause
Elimination
Controller is
not ready
Data transmission to SMCI36
is not possible (communication
error):
Wrong COM port selected.
In the <Communication> tab, select
the PC port to which you connected
the SMCI36 (e.g. "COM-1"). The port
used can be found in the device
manager of your PC.
Wrong baud rate setting.
Select the baud rate 115200 bps in
the <Communication> tab.
The communication cable is
not connected or is
interrupted.
Only use the recommended ZK-
RS485-USB converter from
Nanotec.
A non-existent motor number
(module number) is set.
Set the correct module address.
See separate NanoPro manual.
The power supply of the
SMCI36 is interrupted.
Check power supply, switch on if
necessary.
Another open program is
blocking the COM port to
which the SMCI36 is
connected.
Close the 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 SMCI36 switches back to the
"Ready" state. The data can then be
resent to the controller.
Transmission
fault
Data transmission to the
SMCI36 is disturbed (sender
or receiver are disturbed).
Check that the motor connection is
correctly wired. We recommend
using Nanotec converter
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.
