BLV Series Speed Control Modbus

Post by Hasan1493 » Tue May 04, 2021 5:17 am

When I examine the datasheets, the rotation speed can be adjusted as digital in the 1st Mode of the BLVD40NM driver (hm5114-2e page 28). But I could not find how this check would be carried out.

Hello,

To change the Mode setting on the BLV driver via Modbus you would have to write to the the Analog input signal selection register 10E3h (lower). This would be on page 27 of the manual below. The registers for the digital speeds are on page 25.
