Practical use of differential line receiver – Index signal voltage conversion (5V TTL into OC 24V).
Since some servo drives do not have a digital output of Index signal, what makes impossible to use precise homing function in CSMIO/IP-S controller – we present an alternative solution.
In the diagram below you can see situation where index signal is taken directly from a servo drive encoder and converted into OC 24V signal by the differential line receiver. OC 24V signal can be easily connected directly to CSMIO/IP-S controller. You should remember to use a pull-up resistor.
