Differences in Terms for Rotary Servomotors and Linear
Servomotors
There are differences in the terms that are used for Rotary Servomotors and
Linear Servomotors. This manual primarily describes Rotary Servomotors. If
you are using a Linear Servomotor, you need to interpret the terms as given
in the following table.
Notation Used in this Manual
Notation for Reverse Signals
The names of reverse signals (i.e., ones that are valid when low) are written
with a forward slash (/) before the signal abbreviation.
Notation Example
BK is written as /BK.
