System configuration and wiring
•
Provides differential outputs of the encoder signals
(A, B and Z phases) that come from the divider
(equivalent to RS422 signals).
•
The logical relation between A and B phases can be selected by
Pr45 (Output Pulse Logic Inversion).
• Not insulated
• Z-phase signal output in an open collector
• Not insulated
• Signal ground for pulse output
•
Internally isolated from the control power (COM-).

•
Outputs the motor speed, or voltage in proportion to the
commanded speed with polarity.
+ : CCW rotation
– : CW rotation
•
Use Pr07 (Velocity Monitor Selection) to switch between actual
and commanded speed, and to define the relation between
speed and output voltage.
•
Outputs the output torque, or voltage in proportion to the position
error with polarity.
+ : generating CCW-torque
– : Fgenerating CW-torque
•
Use Pr08 (Torque Monitor Selection) to switch between torque
and positional error, and to define the relation
between torque/positional error and output voltage.
• Signal ground for monitor signal
• Internally isolated from the control power (COM-
).
