PO2 Open Collector Output
• Outputs Z-phase signals among those
from the encoder. The outputs are non-
insulated.
• Receive these signal with high-speed
photo coupler at controller side, since
these Z-phase signal width is normally
narrow.
shows a pair of twisted wires.
AO Analogue Monitor Output
• This output is the velocity monitor signal
(SP) or torque monitor signal (IM).
• The signal range is approx. 0 to ± 9V.
• The output impedance is 1kΩ. Pay atten-
tion to the input impedance of your mea-
suring instruments and
external circuits connected.

1) Velocity monitor signal (SP): 8r/min./
LSB calculated from 6V/3000r/min
(Pr07 = 3)
2) Torque monitor signal (IM): 0.4%/LSB
calculated from 3V/rated value (100%)
