RKII MODBUS RTU SETUP

Post by akoipnoisacpp » Wed Apr 22, 2020 6:24 am

Hi,

I'm using an RKSD507-CD drive and PKE591EAC stepper motor. I'm also using the MODBUS RTU networking with BRX PLC (with DO-More software). I followed the steps 1 thru 5 of RKII user manual (pages 138 thru 142). My problem is that the motor does not run when I send the start ON data after sending the operation type, position, speed, acceleration and deceleration data. The C-DAT/C-ERR led will only blink once (green) after sending the operation data, and blink once (green) after the start ON data is sent. Attached are pictures that will show the PLC and drive setting.
