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.
Parameter MIN MAX Units
Accel / Decel 65/(2^32) 512 counts/sample^2
MaxV (maximum velocity) 0 2048 counts/sample
Max move distance 0 +/- 2^31 counts
Stacks and queues depth limitations
