INVERTER FUNCTIONS ENABLED WITH FR-A8APA

 Parameter for detector
Setting item
Encoder rotation direction
Number of detector pulses (Signal period)
Encoder signal loss detection enable/disable selection
 Maximum setting speed of the inverter
When the FR-A8APA is installed, operate the inverter so that the encoder pulse frequency is kept at 100 kHz or lower. If a
speed higher than the maximum speed is set, the speed is clamped at the maximum speed.
NOTE
• While the motor stops, signal loss may not be detected depending on the motor shaft position. Before starting the
operation, check the wiring.
• The availability of the functions differ according to the specifications of the inverter. Refer to the Instruction Manual of
the Inverter.
• When the motor rotation in the low-speed range (60 r/min or lower) is unstable, check if the encoder cables are
properly connected.
