4. Servo Setup
Before you start the servo, you can follow the below steps.
Install Encoder and Hall sensor
Encoder and Hall sensor provide information of the motor shaft position and rotor
magnetic field orientation. The output signals from the Hall sensor have absolute
phase information which is used at motor startup. If your motor has no encoder and
hall sensor, you must have an encoder (more than 200 lines) and hall sensor properly
mounted on the motor before you start.
There are some modules which can output signals both for encoder and hall sensor.
Please assemble the selected module according to its factory manual. Leadshine also
offer ACM series AC servo motors for matching the ACS806. Please use shielded
cables and separate encoder signal cable from interference sources, such as motor
wires and power wires at least 5 cm.
Prepare Power Supply
Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the Drive.
However, unregulated power supplies are preferred due to their ability to withstand
current surge. If regulated power supplies (such as most switching supplies.) are
indeed used, it is important to have large current output rating to avoid problems like
current clamp, for example using 4A supply for 3A motor-drive operation. On the
other hand, if unregulated supply is used, one may use a power supply of lower
current rating than that of motor (typically 50%～70% of motor current). The reason
is that the Drive draws current from the power supply capacitor of the unregulated
supply only during the ON duration of the PWM cycle, but not during the OFF
duration. Therefore, the average current withdrawn from power supply is
