4.18 Disconnection/incorrect wiring detection function
Setting method
Enable/disable the servo motor incorrect wiring detection function in [Pr. PC16.4 Servo motor incorrect wiring detection
function selection], and set when to execute the function in [Pr. PC16.5 Servo motor incorrect wiring detection function
execution method selection]. Execute the servo motor incorrect wiring detection function when changing the wiring of the
servo amplifier.
1.
After setting "1" (enabled) in [Pr. PC16.4], cycle the power or perform the software reset or the communication reset.
2.
Turn on the servo-on command.
3.
The servo motor incorrect wiring detection function will be executed. Upon detection of incorrect wiring of the servo
motor, [AL. 139 Open-phase error] occurs. The servo-on state becomes active if the servo motor wiring is correct. The
time until the servo amplifier actually enters in the servo-on state after the servo-on command is turned on may be
extended by up to 3.0 s.
4.
If "0" (initial value) is set in [Pr. PC16.5], [Pr. PC16.4] will be changed to "0" (disabled) after the servo motor incorrect
wiring detection function is executed.
5.
The servo motor incorrect wiring detection function will not be executed from the next servo-on. The time until the servo
amplifier actually enters in the servo-on state after the servo-on command is turned on will be the same as when the
function is disabled. To use the servo motor incorrect wiring detection function after changing the wiring, repeat
procedure 1.
