• Use the near-point dog method 2) or count method 3) as
the zero point return method. (Refer to section 8.2.)
• When performing data setting method machine zero
point return control, rotate the servomotor more than one
turn and then perform data setting method machine zero
point return control again.
Reset the axis error (refer to [3] in section 14.1) and start a
machine zero point return again.
Check whether "Absolute position detection valid" is set to
the servo basic parameter "Amplifier setting" for start of
communication with the servo amplifier. (Refer to (11) in
section 7.2.)
Correct the JOG speed to within the setting range. (Refer
to section 11.2)
In the sequence program, remove the part relevant to the
setting in the buffer memory address 1146. Then, power
up the system again or reset the PLC CPU.
Examine the condition data number. (Refer to Da. 13 in
section 5.4)
Correct the condition operator.

Correct the positioning data.
Examine the positioning address.
• Correct the center point address (positioning address).
• Correct the end point address (arc address).
Correct the allowable range value of the arc interpolation
error.
