Output Circuit Interfaces
Any of the following three types of servo amplifier output circuits can
be used. Connect an input circuit at the host controller following one of
these types.
Connecting to a Line-driver Output Circuit
Encoder serial data converted to two-phase (A and B phase) pulse
output signals (PAO, /PAO, PBO, /PBO), origin pulse signals (PCO,
/PCO) and S phase rotation signals (PCO, /PCO) are output via line-
driver output circuits that normally comprise the position control
system at the host controller. Connect the line-driver output circuit
through a line receiver circuit at the host controller.
See 3.5 Wiring Encoders for connection circuit examples.
Connecting to an Open-collector Output Circuit
Alarm code signals are output from open-collector transistor output
circuits.
Connect an open-collector output circuit through an optocoupler,
relay, or line receiver circuit.
Note: The maximum allowable voltage and current capacities for open-collector circuits are:
Voltage: 30V
Current: 20mA
