A08757 CAN: Set COB-ID invalid
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: For online operation, the appropriate COB-ID must be set invalid before mapping.
Example:
Mapping for RPDO 1 should be changed (p8710[0]).
--> set p8700[0] = C00006E0 hex (invalid COB-ID)
--> set p8710[0] as required.
--> p8700[0] enter a valid COB-ID
Remedy: Set the COB-ID to invalid.
A08758 CAN: Maximum number of valid PDO exceeded
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: An attempt was made to exceed the maximum number of valid PDO.
Alarm value (r2124, interpret decimal):
1:
An attempt was made to exceed the total number of valid RPDO of all CANopen supported drive objects.
As a result of the hardware, the limit is 25 valid RPDO.
2:
An attempt was made to exceed the total number of valid TPDO of all CANopen supported drive objects.
The limit is defined by the following ratio:
CAN sampling time (p8848) / CAN minimum processing time (r8739)
Note:
RPDO: Receive Process Data Object
TPDO: Transmit Process Data Object
See also: r8739 (Minimum CAN processing time), r8742 (CAN PDO available number)
Remedy: Comply with the limit for the maximum number of valid RPDO or TPDO.
Apply one of the following options to delete the alarm:
- successfully write to the COB ID index of a PDO communication parameter (p870x[0], p872x[0]).
- change CANopen NMT state.
- execute CANopen NMT command reset node.
- execute CANopen NMT command reset communication.
- carry out a warm restart (p0009 = 30, p0976 = 2).
- carry out a POWER ON (switch off/on).
Note:
The remaining available RPDO or TPDO are indicated in r8742.
