ENCODER FEEDBACK CONTROL—A500(L)
During acceleration/deceleration, switching cannot be made using the S-shaped acceleration/
deceleration C switching terminal (X20). When X20 is switched either ON or OFF during either
acceleration or deceleration, the effect of the switch (to select a different acceleration or
deceleration shape) does not take effect until either the acceleration or deceleration has stopped
(i.e. a stable speed has been reached).
Speed variation ratio

DC power supply
*1 Load variation 100% indicates the maximum continuous operation torque value of the motor output characteristic
(refer to the relevent catalog or FR-A500 series technical information) to the running frequency.
±0.02% of the maximum speed (3600r/min) in vector control mode
(load variation 0 to 100% at 6Hz or more). (*1)
1:1000 in vector control mode.
• Speed feedback range setting.
• Feedback gain setting.
• Encoder rotation direction setting.
A 5VDC power supply is required for the encoder and option unit.
The 5V power supply can be shared between orientation control and encoder feedback
This power supply is optional.
Power supply 5VDC, current capacity 400mA or more.
(Normally approximately 350mA for encoder and 50mA for option unit)
