Connection of motor with encoder (vector control)

2.8
Connection of motor with encoder (vector
control)
Using an encoder-equipped motor together with the plug-in option FR-A8AP enables speed, torque, and positioning control
operations under orientation control, encoder feedback control, and full-scale vector control.

NOTE
• When the encoder's output voltage differs from its input power supply voltage, the signal loss detection (E.ECT) may occur.
• Incorrect wiring or faulty setting to the encoder will cause a fault such as an overcurrent (E.OC[ ]) and an inverter overload
(E.THT).
Correctly perform the encoder wiring and setting.

Description
Used for installation to the inverter.
Connected with the encoder.
Switches the encoder type (differential line driver/complementary).
Not used.
Switches ON or OFF the internal terminating resistor.
Do not change from the initially-set status. (Switches 1 and 2 are
OFF .)

Connected to the option connector of the inverter.
Not used.
A-, B- and Z-phase signals are input from the encoder.
Input terminal for the encoder power supply.
Connect the external power supply (5 V, 12 V, 15 V, 24 V) and the encoder
power cable. When the encoder output is the differential line driver type, only
5 V can be input. Make the voltage of the external power supply same as the
encoder output voltage. (Check the encoder specification.)
