Elmo Bassoon - Fault Protection & System Architecture

Bassoon Installation Guide Introduction
MAN-BASIG (Ver 1.4)
2-3
y Tachometer and Potentiometer
 Two inputs for Tachometer Feedback:
y Up to ±50 VDC
y Up to ±20 VDC
 Potentiometer Feedback:
y 0 ~ 5 V voltage range
y Resistance: 100 Ω to 1000 Ω
y Elmo drives provide supply voltage for all the feedback options
2.2.7 Fault Protection
The Bassoon includes built-in protection against possible fault conditions, including:
y Software error handling
y Status reporting for a large number of possible fault conditions
y Protection against conditions such as excessive temperature,
under/over voltage, loss of commutation signal, short circuits
between the motor power outputs and between each output and
power input/return
y Recovery from loss of commutation signals and from communication
errors
