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.
