Encoder Connections

ems-i
All
DRO and linear encoders (apart from special products) have the same encoder
connection specification and pin-out. As such any
DRO. In addition, all of these DRO and encoders are full industrial EIA 422 differential and
screened to ensure the highest levels of noise immunity and performance.

Power-up Sequence

On power-up the EM250 DRO will make a few 'BEEPS' and all the axis windows will cycle
through the LED numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and the message windows will show EMS-I.
This is to test the beep and the LED displays. It also puts the DRO under maximum current
load. As such if there is an issue with the DRO supply the DRO will most likely have an issue
during this process. If this occurs please consult the Troubleshooting section for assistance.
EM250 Models
The EM250 DRO is available in 4-versions, each machine type specific.
● 2-axes Lathe
● 3-axes Lathe
● 2-axes Milling
● 3-axes Milling
