2.16 Limitations and restrictions

Communication Interfaces usage restrictions

Simultaneous connection to RS232 and RS485 is allowed for the purpose of retransmitting
(conversion) between interfaces.

Usage of either RS232 or RS485 simultaneously with Ethernet may lead to unpredictable
behavior since drive will attempt to perform commands from both interfaces concurrently.


Motion parameters limitation
Due to finite precision in the calculations there are some restrictions for acceleration/deceleration and
max velocity for the move. If you receive arithmetic faults during your program execution it is likely due to
these limitations. Min/Max values are expressed in counts or counts/sample, where sample - position
loop sample interval and equal 256uS.
