IMPROVED MODBUS COMMUNICATION
As of Firmware version 2.0, the Modbus Communication has been improved to ensure speed and stability. This change will affect customers upgrading from firmware 1.x.
What do I need to do when upgrading from FW 1.x to 2.x?
After upgrading your motor, all you need to do is to swap the Modbus Communication Cables A and B, pin 7 and 8.
I can’t do a Firmware update after having changed to FW 2.x
If the motor originally had FW 1.x, the bootloader will still communicate using the legacy setting of the Modbus.
Switch the Modbus cables after setting the motor in FW mode from Simplex Motion Tool, before manually shorting IN5 and IN6 at startup.
My motor connects sporadically after upgrading to FW 2.0
Check your Modbus Communication cables; A and B cables might have to be swapped. The motor has an automatic function to detect if the Modbus communication is the improved FW 2.x or the legacy FW 1.x.
The standard setting of the motor can be saved by storing data in the non-volatile memory.
