SBM – Sensor Board Encoder / Multiturn (only for MASTERDRIVES Motion Control)
The SBM optional board (Sensor Board Multiturn / sin-/cos-Encoder)
enables sin-/cos-encoder phase-angle sensors and multiturn phase-
angle sensors to be connected and evaluated.
Encoders with a pulse number from 4 to 16384 are supported.
The usual communication protocols (EnDat and SSI) with baud rates
from 100 kHz to 2 MHz are supported for the multiturn phase-angle
sensor.
The supply voltage for the encoders can be set to 5 V, 7.5 V or 15 V.
By connecting the sense cable, the voltage at the encoder input can be
monitored and adjusted in the case of long encoder cables (4-wire
principle).
In addition to the processing of encoder signals, the motor temperature
is also sensed on this board (either a KTY or a PTC sensor).
The signals A+, A-, B+, B-, zero+ and zero- are provided by the pulse
encoder simulation via an additional front connector in accordance with
standard RS422. The indicated number of pulses/revolution
corresponds to the pulse number of the encoder or the multiturn
encoder. The types ERN 1387 / 1381 (sine/cosine encoder) and
EQN 1324 (multiturn encoder) each have 2048 pulses.
The SBM2 board additionally enables an offset correction of the signals
to be made and can therefore be used for an external encoder with a
high resolution.
