7 PDO Service
7.1
General
The device supports TPDO1 and TPDO2. PDOs are only transmitted in NMT operational mode.
7.2
PDO transmission types
The following transmission types are supported (object 180xh-2):
Synchronous transmission (1-240)
Asynchronous transmission (255)
Manufacturer transmission (254)
RTR-only transmission, event-driven (253)
Both PDOs support all transmission types.
Transmission type 253:
The PDO is only transmitted on request (remote transmission request).
Transmission type 255 and 254: The PDO is transmitted timer driven. The time interval between 2 PDOs can be
adapted in the object 180xh-5
Transmission type 1-240:
The PDO is transmitted after the n-th sync frame.
Transmission type 1:
The PDO is transmitted after one sync frame.
Transmission type 2:
The PDO is transmitted after two sync frames.
etc.
7.3
COB-ID
The COB-ID for both PDOs is changeable (in Object 180xh-1)
Default Values are:
TPDO1: 180h + node ID
TPDO2: 280h + node ID
Changes will be applied immediately.
The COB-ID is stored internally as a difference to the default COB-ID. Example:
Node ID: 1
COB-ID TPDO1: 181h
(Default value)
COB-ID TPDO1: 187h
(Changed by user)
Node ID: 9
COB-ID TPDO1: 189h
(Adapted automatic)
7.4
PDO mapping
The encoder supports dynamic mapping.
7.4.1
Mappable objects
The following objects are mappable:
Mapping content
Mapping entry
Description
Position encoder
0x60040020
Object 6004h Subindex 00h, data length 32 Bit
Speed encoder
0x60300120
Object 6030h Subindex 01h, data length 32 Bit
Alarms
0x65030010
Object 6503h Subindex 00h, data length 16 Bit
Warnings
0x65050010
Object 6505h Subindex 00h, data length 16 Bit
Diagnostic
0x21170010
Object 2117h Subindex 00h, data length 16 Bit
Speed [rpm]
0x21180010
Object 2118h Subindex 00h, data length 16 Bit
Time Stamp
0x21200010
Object 2120h Subindex 00h, data length 16 Bit
To change PDO mapping, disabling the mapping by writing 0 to 0x1A0x-0 is required first. Write the desired mapping
entry and enable the mapping again by writing the number of PDO contents to 0x1A0x-0.
