Solution
The lower limit of the
mechanical single‑turn
position (modal axis
modulus) is less than 1.
Check the setting of the
mechanical gear ratio, the
upper limit of mechanical
single‑turn position and the
electronic gear ratio when
the servo drive runs in the
absolute rotation mode
(H0201 = 2 or 5).
Reset the mechanical gear
ratio, the upper limit of
mechanical single‑turn
position, and the electronic
gear ratio to ensure the
lower limit of the
mechanical single‑turn
position (modulo axis
modulus) is not below 1.
● E126.0: Process segment number error
Description:
The process segment number exceeds the limit.
Cause
Troubleshooting
Solution
The process segment
number is not 1000 or any
other value from 0 to 15 in
the process segment mode.
Check whether the value of
H22.00 exceeds the specified
range of the technology
segment number (0–15 or
1000).
Write 0...15 to H22.00 in the
technology segment mode.
● E126.1: Process segment internal operation mode error
Description:
The internal operation mode of the process segment exceeds the limit.
Cause
Troubleshooting
Solution
The technology segment
operation mode is not 0, 1,
2, 3, 7, or 8.
Check whether the values of
bit0 to bit3 of the parameter
defined by the faulty
technology segment are 1, 2,
3, 7, and 8.
Set the technology segment
operation mode to 0, 1, 2, 3,
7, and 8 in the technology
segment mode.
● E126.2: Position reference type error in process segment position mode
Description:
The position reference type in the process segment position mode is wrong.
Cause
Troubleshooting
Solution
The position reference type
in the process segment
position mode is not 00
(Absolute reference) or 10
(incremental mode).
Check whether the value of
bit6 or bit7 of the parameter
defined by the faulty
technology segment is 00 or
10.
Set the position reference
type in the process segment
position mode to 00
(Absolute reference) or 10
(Incremental reference).
● E136.0: Encoder ROM motor parameter check error
