A/D converter error
An error was detected in the current FB.
Investigation details Investigation results Remedies SV SP
1 Check the repeatability.
The error is always repeated. Replace the drive unit.
The state returns to normal, but occurs
thereafter.
Check the investigation item No. 2.
2
Check if there is any abnormality in the
unit's ambient environment.
(Ex. Ambient temperature, noise,
grounding)
Take remedies according to the causes of the abnormality in the ambient environment.
Alarm No.
18
Main side detector: Initial communication error
An error was detected in the initial communication with the motor side detector.
Investigation details Investigation results Remedies SV SP
1
Check the servo parameter (SV025.ent)
setting value.
Check the spindle parameter(SP020)
setting value.
The value is not set correctly.
Correctly set SV025 for the servo, and
SP020 for the spindle.
The value is set correctly. Check the investigation item No. 3.
2
Check the detector.
Check if a pulse detector is used for serial
detector specifications. The pulse detector is used. Replace the detector to the serial.
The serial detector is used. Check the investigation item No. 3.
3
Jiggle the detector connectors (drive unit
side and detector side) and check if they are
disconnected. The connector is disconnected (or loose). Correctly install.

detector side. The alarm is on the drive unit side. Replace the drive unit.
The alarm is on the detector side. Check the investigation item No. 6.
6
Check if there is any abnormality in the
detector's ambient environment.
(Ex. Ambient temperature, noise,
grounding)
Take remedies according to the causes of the abnormality in the ambient environment.

Detector communication error in synchronous control:
An error was detected in the machine side detector of the secondary axis at the speed command synchronization control.
Investigation details Investigation results Remedies SV SP
1
Check the servo parameter value of
secondary axis (SV025.pen:position
detector). The value is not set correctly. Correctly set.
The value is set correctly. Check the investigation item No. 2.
2
Check if there are no problems in the
connection between the detector (linear
scale) and MDS-B-HR.
The screw connected to MDS-B-HR is
winded down.
Tighten up the screw.
No problems found in the connector
connection.
Check the investigation item No. 3.
3
Jiggle the detector connectors (drive unit
side and detector side) and check if they are
disconnected. The connector is disconnected (or loose). Correctly install.
The connector is not disconnected. Check the investigation item No. 3.
