■Operation cycle
For each operation cycle, the following number of axes per controller can be set. When the number of axes is more than what
can be set, and an operation cycle other than those below is set, a minor error (error code: 1C83H) occurs.
Operation cycle Number of axes per controller available
0.222[ms] 1 to 2 axes
0.444[ms] 3 to 4 axes
0.888[ms] 5 axes or more
IAI electric actuator controller detection error
When an error occurs on IAI electric actuator controller, the "[St.1068] Servo error detection (R: M32408+32n/Q:
M2408+20n)" turns ON, and the minor error (error code: 1C80H) is stored in "[Md.1005] Servo error code (R: D32008+48n/Q:
D8+20n)". Error codes read from the IAI electric actuator controller are stored in "[Md.1019] Servo amplifier display servo
error code (R: D32028+48n/Q: #8008+20n)".
Also, when an error occurs during home position return by driver home position return method, "Driver operation alarm (b9)"
of "[Md.500] Servo status7 (R: D32038+48n/Q: #8018+20n) turns ON, and the minor error (error code: 194BH) is stored in
"[Md.1005] Servo error code (R: D32008+48n/Q: D8+20n)". Alarms read from the IAI electric actuator controller are stored in
the event history.
Eliminate the error cause, reset the servo amplifier error by turning ON "[Rq.1148] Servo error reset command (R:
M34488+32n/Q: M3208+20n)" and perform re-start. However, "0" is always stored in "[Md.107] Parameter error No. (R:
D32029+48n/Q: #8009+20n)".
Refer to the instruction manual of IAI electric actuator controller for details of the errors.
