Y02 SV commu er: Recv timing err 0051 0002
Details
A communication error has occurred between controller and drive unit.
Remedy
- Take measures against noise.
- Check for any failure of the communication cable connectors between controller and drive unit or
between two drive units.
- Check for any failure of the communication cables between controller and drive unit or between two
drive units.
- A drive unit may be faulty. Take a note of the 7-segment LED contents of each drive unit and contact
the Service Center.
- Update the drive unit software version.
(Note) When two or more "Y02 System alarms" occur at the same time, only the alarm which has
occurred first is displayed.
Y02 Servo communication error: Data ID error 0051 0x03
Details
A communication error has occurred between CNC and drive unit.
The axis ID transferred from the drive unit has changed after initial communication.
x: Drive unit rotary switch No. (0 or later)
Remedy
- Take measures against noise.
(Note 1) When two or more "Y02 System alarms 0051" alarms occur at the same time, only the alarm
which occurs first is displayed. Therefore, the display precedence will be as follows: 0006, 0x04,
0005, 0x20, then 0x03.
(Note 2) Station No. always shows "0" in the alarm details, because C70 has only one communication
channel.
(Note 3) If the error is not cleared with the measures above, the drive unit may have a fault. Take a
note of the 7-segment LED contents of each drive unit and contact service center.
Y02 Servo communication error : Number of received frames 0051 0x04
Details
A communication error has occurred between CNC and drive unit.
The number of received frames was inconsistent in four consecutive communication cycles.
x: The number of received frames subtracted by one (0 or later)
Remedy
- Check for any duplication of rotary switch settings on drive units connected with other drive units.
- Confirm that the number of axes does not exceed the number designated by CNC.
- Check for any failure of the communication cable connectors.
- Check for any failure of the communication cables.
- Take measures against noise.
(Note 1) When two or more "Y02 System alarms 0051" alarms occur at the same time, only the alarm
which occurs first is displayed. Therefore, the display precedence will be as follows: 0006, 0x04,
0005, 0x20, then 0x03.
(Note 2) Station No. always shows "0" in the alarm details, because C70 has only one communication
channel.
(Note 3) If the error is not cleared with the measures above, the drive unit may have a fault. Take a
note of the 7-segment LED contents of each drive unit and contact service center.
