(c) State transition of the servo amplifier display (3-digit, 7-segment LED) at the magnetic pole detection
When the magnetic pole detection with MR Configurator2 is normally executed, the servo amplifier
display (3-digit, 7-segment LED) shows the state as below.
(2) Preparation for the magnetic pole detection
For the magnetic pole detection, use the test operation mode (positioning operation) of MR
Configurator2. Turn off the servo amplifier power, and set the test operation select switch (SW2-1) as
shown below. Turning on the power enables the test operation mode.
