9400 Technology applications | CiA402 device profile

Parameter setting & configuration

Drive initialisation

SDO write request 0x1A00/1 0x60410010 Map the 0x6041 object (statusword) to PDO1-Tx.

SDO write request 0x1A00/2 0x60640020 Map the 0x6064

object (position actual value) to

PDO1-Rx.

SDO write request 0x1A00/0 2 PDO1-Tx contains 2 objects; activate mapping.

SDO write request 0x1C12/1 Selection of the PDO-Rx source

SDO write request 0x1C13/1 Selection of the PDO-Tx source

Initialisation of device profile objects

SDO write request 0x60C2/1 2 Set time base for interpolation of the position

setpoint.

• Time base = 2 x 10

-3

[s] = 2 [ms]

SDO write request 0x60C2/2 0xFD (-3)

SDO write request 0x6092/1 0x10000 Set feed constant for position values in [increments].

• One encoder revolution corresponds to 0x10000,

since the feed is usually already converted into

increments in the master control.

SDO write request 0x6060 7 Select the "Interpolated position mode" operation

mode.

Initialisation of manufacturer-specific objects

SDO write request 0x55A4 0x10000 Configure touch probe for the "homing mode"

operation mode in C02651.

• Touch probe is triggered by motor encoder zero

pulse.

SDO write request 0x55AF 2 Select "2" for "Homing mode" operating mode in

C02640.

Process:

1.Movement in positive direction with profile data

set 1.

2.Reversing to positive travel range limit switch.

3.Positive edge of the reference switch activates

profile data set 2 for the further reference search.

4.Negative edge of the reference switch enables

home position detection.

5.The following positive edge of the encoder zero

pulse/touch probe sensor sets the reference

(0x607C

6.Absolute positioning to target position (C02643)

with profile data set 2

(if 0x60FB/7

= "0").

SDO write request 0x5B9F 4 Write request on the code C01120 (sync source) for

axis synchronisation.

• Value "4" = module in MXI1

Change of the communication status

NMT - - Switch drive to the OPERATIONAL communication

status.

Cyclic process data exchange

PDO1-Rx to the drive - - Transmit the process data to the drive according to

PDO mapping.

SYNC - - Process data synchronisation

PDO1-Tx from the drive - - Receive process data from the drive according to PDO

mapping.
