Integrate the current actual value and torque limit into the communication via the free PDO mapping
In order to integrate the current actual value and torque limit into the communication, you
must switch over from the Predefined Connection Set to the free PDO mapping. The current
actual value and torque limit are integrated as free objects.
In the example, the actual current value is transferred in TPDO1 and the torque limit in
RPDO1, i.e. it is not necessary to create new communication parameters (node ID and
transmission mode). However, you must map the OD indices for the current actual value and
the torque limits and adapt to the BiCo interconnection.
1. Switching over from the Predefined Connection Set to free PDO mapping
In the expert list, set p8744 to 1.
2. Mapping the current actual value (r0068) with TPDO1
●
Define the OD index for the current actual value: 5810
●
Set the COB ID from TPDO1 to "Mapping permissible":
p8720[0] = 400001B2H (mapping not permitted) on p8720.0 = 800001B2H (mapping
permissible)
●
Set p8730[1] = 5810010H - the first four digits are the OD index for the current actual
value (r0068), 00: Sub-index (corresponds to the parameter index) 10: Object size (10H =
16 bit) must be attached to the OD index
●
Reset p8720[0] to 400001B2H
●
r8751 shows which object has been matched to which PZD
3. Mapping the torque limit (p1522) with RPDO1
●
Define the OD index for the torque limit: 5800
●
Set the COB ID from RPDO1 to"Mapping permissible":
Set p8700[0] = 232H (mapping not permissible) to p8700.0 = 80000232H (mapping
permissible)
●
Set p8710[1] = 5800010H - the first four digits are the OD index for the torque limit
(p1522), 010 is CAN-specific and for all linked parameters in free PDO mapping must be
attached to the OD index
●
Reset p8700[0] to 232H
●
r8750 shows which object has been matched to which PZD
