5.2 Interface converter for LECOM−B (RS485)
If the target system is to communicate via LECOM−B (RS485), an intelligent interface converter RS232
óRS485 is required which is able to automatically reverse the direction of communication. The Lenze
interface converter 2100 does not meet this requirement.
We therefore recommend the following product:
I−7520 isolated RS232 to RS485 converter

5.3 Frequently asked questions and answers
Error Cause Remedy
Parameter set files
cannot be read. You tried to read parameter set files which
were generated with the "Lemoc2"
DOS−program. GDC uses another file format for the saving of drive
parameters.
Transmit the parameter set from the controller to the
PC and save it with GDC.
No communication with
the controller. The PC system cable is wrong. Check the wiring of the system cable.
(For the assignment of the system cable refer to the
GDC online help.)
Controller is switched off or LECOM−A/B
module 2102 has no power supply. Connect power supply to controller and check the
connection to the controller.
In the case of external voltage supply at the terminals
39 and 59, check the voltage (see operating
instructions of the controller).
Incorrect COM port selected. Set correct COM port via Options WCommunication
Interface parameters are set incorrectly. You can change the interface parameters using the
Windows Control Panel:
·
COM1: address 03F8, IRQ 4
·
COM2: address 02F8, IRQ 3
The Windows configuration is incorrect.
Note: You cannot access the COM ports via
the Windows program "Terminal"
(Startup/Programs/Accessories), either. Install Windows again or eliminate configuration errors
in the "System.ini" file.
GDC with system bus
Error Cause Remedy
GDC or Windows crash Removing PC system bus module which
Windows is running. Do not remove PC system bus module from the
interface or plug into the interface while Windows is
running.
