2.4 Connection of motor with encoder (vector control)
Orientation control and encoder feedback control, and speed control, torque control and position control by full-scale
vector control operation can be performed using a motor with encoder and a plug-in option FR-A7AP.
(1) Structure of the FR-A7AP
(2) Terminals of the FR-A7AP
Terminal Terminal Name Description
PA1
Encoder A-phase signal input terminal
A-, B- and Z-phase signals are input from the encoder.
PA2 Encoder A-phase inverse signal input terminal
PB1
Encoder B-phase signal input terminal
PB2
Encoder B-phase inverse signal input terminal
PZ1 Encoder Z-phase signal input terminal
PZ2
Encoder Z-phase inversion signal input terminal
PG
Encoder power supply (positive side) input terminal
Input terminal for the encoder power supply.
Connect the external power supply (5V, 12V, 15V, 24V) and the
encoder power cable. Make sure the voltage of the external
power supply is the same as the encoder output voltage. (Check
the encoder specification.)
SD
Encoder power supply ground terminal
PIN
Not used.
PO
CAUTION
When the input power supply voltage to the encoder and its output voltage differ, the signal loss detection (E.ECT) may occur.
