Open Collector Output
PO2
• 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.

CN MON Connector
Monitor Circuit (Output Circuit)
AO
Analogue Monitor Output
• Output from CN MON Connector
• 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.
