2.
When TC (Analog speed command) is inputted from the controller and RS1 (Forward rotation start) or RS2 (Reverse
rotation start) is turned on, the servo motor starts operating. Give a low torque 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
