Parameter setting & configuration
Drive initialisation
SDO write request
0x1A00/1
0x60410010 Map the
object (statusword) to PDO1-Tx.
SDO write request
0x1A00/2
0x60640020 Map the
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
(
).
6.Absolute positioning to target position (C02643)
with profile data set 2
(if
= "0").
SDO write request
0x5B9F
4
Write request on the code C01120 (sync source) for
axis synchronisation.
• Value "4" = module in MXI1
