PDO default mapping
The servo amplifier supports the variable PDO mapping function, which can select objects transmitted and
received in PDO communication. For changing the PDO mapping, refer to the following.
RxPDO default mapping
With the RxPDO default mapping, a master station (controller) transmits command data to a slave station (servo amplifier)
using an RxPDO in the array shown in the following table.
Map No.
Initial mapping settings
Applications expected to be used for initial
mapping
1st RxPDO map
A-axis: 1600h
B-axis: 1610h
C-axis: 1620h
Modes of operation (Obj. 6060h)
Padding (1 byte)
Controlword (Obj. 6040h)
Control DI 1 (Obj. 2D01h)
Control DI 2 (Obj. 2D02h)
Control DI 3 (Obj. 2D03h)
Target position (Obj. 607Ah)
Target velocity (Obj. 60FFh)
Velocity limit value (Obj. 2D20h)
Target torque (Obj. 6071h)
Cyclic synchronous position mode (csp)
Cyclic synchronous velocity mode (csv)
Cyclic synchronous torque mode (cst)
Homing mode (hm)
This initial mapping is for an application in which the
modes above are switched and used.
The following function can be used together.
• Speed limit function (in cst)
