Interface Circuit (Output)
PO2
Open collector output

control mode
P S T F
• Feeds out the Z-phase signal among the encoder signals in open collector. This output is
not insulated.
• Receive this output with high-speed photocouplers at the host side, since the pulse width of
the Z-phase signal is narrow.
• For function, refer to P.3-51.
AO
Analog monitor output

control mode
P S T F
• There are two outputs, the speed monitor signal output (SP) and the torque monitor
signal output (IM)
• Output signal width is ±10 V.
• The output impedance is 1 kΩ. 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 6 V/3000 r/min, the resolution converted to speed is 4 r/min/8 mV.
(2) Torque monitor output (IM)
With a relation of 2 V/rated torque (100 %), the resolution converted to torque is
0.4 %/8 mV.
• For function, refer to P.3-52.
