Change of
direction
is not
possible
Fault description:
The machine can only move in one direction when the Shaft + (or shaft-)
key is used in "Manual" mode, and the direction cannot be changed.
Diagnostic steps
Check whether the drive is damaged.
If using a third-party drive, it is necessary to verify the compatibility between
the system and the drive.

Positioning
error
Fault description:
The operating position of the machine coordinate system is not accurate.
Diagnostic steps
Check whether the settings of machine parameters
MD31060/MD31020/MD31400
parameters.
1. MD31030 → leadscrew pitch value storage
2. MD31050/MD31060 → shaft deceleration rate
3. MD31020 = MD31400 → encoder line number (set to 10000 when
using the V60 drive)
Note: Check whether there is play on the drive encoder.
Check the drive parameters. Do not set up the deceleration rate parameters
in the drive.
Check whether the machine installation is stable.
Check whether the mechanical coupling is loose / the belt is slipping.
Check whether it is necessary to adjust the compensation of the leadscrew
pitch and the backlash.
