Some data from the drive is not part of the standard MEI I/O. Although, it can be monitored in real-time from the drive. For more information on how to monitor real-time data from the drive, see Drive Monitor.
List of real-time monitor fields. This is a partial list of supported fields. Consult your drive manual for a complete list.
This is a quick list of error and status
codes found on the 7-segment LED display on the CD SynqNet drive.
NOTE:This list is provided for the user's
convenience. Please refer to the documentation from your drive supplier
for the most current data.
Description
|
Comments
|
Priority
|
Steady '2' |
Torque Mode: the drive is configured and ready to
be enabled |
|
Decimal point |
The decimal point is on when the drive is enabled |
|
Flashing '2' |
When using MENCTYPE 4 (WNS encoder initialization),
this indicates that the drive is configured and ready to be enabled.
The encoder initialization process will begin when the drive is
enabled. |
|
Steady 'F' |
Drive in foldback (current limiting) |
|
Flashing 'e' |
Flash memory checksum failure (at power up). Need
to re-configure the drive's parameters and SAVE them in the flash
memory. |
1
(highest priority)
|
Flashing 'P' |
Over-current. This fault can only be cleared by cycling
the power of the drive |
2
|
Flashing 'o' |
Over-voltage |
3
|
Flashing 't' |
Drive over-temperature |
4
|
Flashing 'u' |
Under-voltage |
5
|
Alternating '1'and minus sign (-) |
No comp: The drive is not configured. Load a configuration
file and execute the CONFIG instruction. |
6
|
E |
EEPROM fault. This is a hardware failure |
7
|
Alternating 'A'and '1' |
Internal failure of positive analog supply voltage
|
8
|
Alternating 'A'and '2' |
Internal failure of negative analog supply voltage |
9
|
Alternating 'c' and '1' |
SynqNet communications fault. Check that the SynqNet
cables are in place. |
10
|
Alternating 'r' and '4' |
Encoder wire break |
11
|
Alternating 'r' and '6' |
Illegal Halls. A state of either '000' or '111' was
detected on the Halls signals. |
12
|
Alternating 'r' and '5' |
Index line break |
13
|
Alternating '4' and minus sign (-) |
The commutation initialization process has failed.
Read the WNSERR value (parameter 0x2F) to see what caused the failure. |
14
|
Alternating 'r' and '1' and '0' |
EnDat communications fault. Check that the EnDat encoder
is connected, or check the MENCTYPE parameter to verify that it
is correctly set. |
15
|
Alternating 'r' and '8' |
A/B out of range. For a sine encoder and a resolver,
the drive checks that sin^2 + cos^2 = 1, within tolerance. This
fault indicates that the signal amplitudes are out of tolerance.
This fault is not relevant for Encoder feedback. |
16
|
Flashing 'H' |
Motor over-temperature |
17
(lowest priority)
|
Alternating 'A' and '3' |
Internal failure of positive and negative analog supply
voltages |
|
Three horizontal bars |
Watchdog: drive firmware failure |
