Kollmorgen Servostar CD SynqNet Drive

 

Servostar CD SynqNet Drive

The CD SynqNet is designed as a Torque drive, with torque command being provided at high servo update rates from the SynqNet™ controller. Extensive I/O support is provided, with both function-specific inputs, such as Limit Switches, Home and Brake, and numerous general purpose I/Os.

The CD drive is a 1-axis servo drive when using C0FE0027 FPGA.  When using the C0FE0034 FPGA the CD drive has an extra axis with pulse/dir outputs, which can be connected to an external pulse drive.

Drive Monitor: Monitoring Real-time Data from Drive

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.

Error Status Codes

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
