Y02 Servo communication error : Initial communication error 0051 0x20
Details
A communication error has occurred between CNC and drive unit.
A drive unit stopped due to transition failure from initial communication to runtime.
x: Drive unit rotary switch No. (0 or later)
Remedy
- Confirm that "the spindle drive unit rotary switch No. + 1" does not duplicate with the lower two digits
in "#1021 mcp_no (Drive unit I/F channel No. (servo)".
- Confirm that "the servo drive unit rotary switch No. + 1" does not duplicate with the lower two digits in
"#3031 smcp_no (Drive unit I/F channel No. (spindle)".
(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 SV commu er: Node detect error 0051 xy30
Details
A communication error has occurred between controller and drive unit.
No response from drive unit to the request from NC when setting network configuration.
x: Channel No. (from 0)
y: Station No. (from 0)
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 SV commu er: Commu not support 0051 xy31
Details
A communication error has occurred between controller and drive unit.
Drive unit's software version doesn't support the communication mode that the controller requires.
x: Channel No. (from 0)
y: Station No. (from 0)
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.
