1) The inductive encoders with product IDs "EA" and "EB" replace the encoder types with model numbers "E2" and "E3". These encoders should be used in
all new applications.
2) The "EB" encoder type requires the following versions of our servo drives or inverter modules:
• ACOPOS: V2.090 or later
• ACOPOSmulti: V2.031 or later

6.2 Resolver
BRX resolvers are used in 8JSA servo motors. These resolvers are fed with a single sinusoidal signal (reference
signal) and return as a result two sinusoidal signals whose amplitude changes sinusoidally or cosinusoidally with
the angular position.

Accuracy 10 angular minutes
Vibration during operation
10 < f ≤ 500 Hz
≤196 m/s²
