Status Display
Mode
This mode displays the internal Servo Driver status using bit display (LED lit/not lit) and
symbol display (7-segment 3-digit LEDs).
Bit display: Control-circuit power supply ON display, main-circuit power supply ON dis-
play, baseblock, in position, speed conformity, rotation detection, command pulses be-
ing input, speed command being input, torque command being input, deviation counter
reset signal being input.
Symbol display: Baseblock (bb), operating (run), forward rotation prohibited (Pot), re-
verse rotation prohibited (not), alarm display (A.
