(2) Positioning control errors (1100 to 1199)

These errors are detected at the positioning control.

The error codes, causes, processing and corrective actions are shown in Table 1.9.

• The power supply of the servo amplifier turned off during positioning control. (Servo not installed status detection, cable fault, etc.)

• Home position return did not complete normally without stop within the in-position range of home position at the home position return.

• Q172EX or encoder hardware error.

• Disconnected encoder cable.

• A synchronous encoder set in the system setting differs

from a synchronous encoder actually connected.

• Q170ENC is connected to Q172EX/Q172EX-S1.
