3.
When VC (Analog speed command) is inputted from the controller and ST1 (Forward rotation start) or ST2 (Reverse
rotation start) is turned on, the servo motor starts operating. Give a low speed command at first to check the servo motor
operations such as the rotation direction. If the servo motor does not operate in the intended direction, check the input
signal.
