HALL
Note:
If the servo drives are manufactured before week 50 of year 2017 (serial numbers: before T1750 and
1.
W1750), they only support Hall sensors with
built-in pull-up resistors. If there is no built-in pull-up resistors, you need to connect to external ones.
If the servo drives are manufactured in week 50 of year 2017 or later (serial numbers: T1750 and
2.
W1750, or later), the servo drives support Hall sensors with or without built-in pull-up resistors.
