Output Circuit
SO1 SO2 Sequence output circuit
• The output circuit is composed of open collector transistor
outputs in the Darlington connection, and connect to relays or
photo-couplers.
• There exists collector to emitter voltage, V
1V at transistor-ON, due to the Darlington connection of the
output or. Note that normal TTL IC cannot be directly connec-
ted since it does not meet VIL.
• There are two types of output, one which emitter side of the
output transistor is independent and is connectable individual-
ly, and the one which is common to – side of the control pow-
er supply (COM–).
• If a recommended primary current value of the photo-coupler
is 10mA, decide the resistor value using the formula of the
right Fig.
For the recommended primary current value, refer to the data sheet of apparatus or photo-coupler to be used.
PO1 Line driver (Differential output) output
• Feeds out the divided encoder outputs (A, B and Z-phase) in
differential through each line driver.
• At the host side, receive these in line receiver. Install a termi-
nal resistor (approx. 330Ω) between line receiver inputs with-
out fail.
• These outputs are not insulated.
PO2 Open collector output
• Feeds out the Z-phase signal among the encoder signals in
open collector. This output is not insulated.
• Receive this output with high-speed photo couplers at the
host side, since the pulse width of the Z-phase signal is nar-
row.
AO Analog monitor output
• There are two outputs, the speed monitor signal output (SP)
and the torque monitor signal output (IM)
• Output signal width is ±10V.
• The output impedance is 1kΩ. Pay an attention to the input
impedance of the measuring instrument or the external circuit
to be connected.
<Resolution>
(1) Speed monitor output (SP)
With a setup of 6V/3000r/min (Pr07=3), the resolution converted to speed is 8r/min/16mV.
(2) Torque monitor output (IM)
With a relation of 3V/rated torque (100%), the resolution converted to torque is 0.4%/12mV.
