6-2 Troubleshooting MN1276
Table 6-1 Operating Mode Indications Continued
Ready Monitor Status Cause
Red A EEPROM checksum error. The personality must be downloaded to
EEPROM and reset the control. If problem
remains, contact Baldor.
Red c Velocity data in the EEPROM failed. The velocity data must be downloaded to
EEPROM and reset the control. If problem
remains, contact Baldor.
Green C CAN bus problem detected. (“C” blinking) A communication error on the
CAN bus exists. The control is still
connected to the CAN bus.
Red C CAN bus problem detected. (“C” blinking) A communication error on the
CAN bus exists. The control will attempt
resynchronization to establish the CAN bus.
Green d Control Disabled. Disable mode activated by hardware or
software.
Green E Following Error. The following error exceeded the user
defined value of the Following Error Band.
This error is not stored and goes away when
the following error is reduced to within limits.
Green F Fatal Following Error. The following error exceeded the user
defined value of the Following Fatal Error.
The following error preset level is
“Operation Mode ( Pulse Follower”
This error is stored and must be cleared by
the operator, but operation continues as
long as the error is less than "2
15
("32768).
Green H Hold-Position mode. Hold mode activated by hardware or
software.
Green J Jog mode. Jog mode activated by hardware or software.
Red L Both limit switches active. Defective or missing limit switch or wiring.
Green P In Position. The following error is less than the user
defined preset value.
Red U EPROM version fault. The personality must be downloaded to
EEPROM and reset the control.
Red u EEPROM version fault. The personality must be downloaded to
EEPROM and reset the control.
It is important to connect the motor leads U, V and W correctly at the X1 connector
of the control. Incorrect wiring can cause erratic operation including moves at
peak force until the overcurrent limit trips. This will result in a display of “7” and a
“6” on the monitor. If erratic movement of the motor occurs, turn off power
immediately and check the connections of the motor, hall sensors and encoder.
