Index of MD for speed setpoint routing
The index [n] of the machine data for setpoint routing is coded with 0 for setpoint assignment
with default setting 1.
Speed setpoint routing
The following machine data need to be parameterized for each setpoint branch:
MD30100 $MA_CTRLOUT_SEGMENT_NR[n] (setpoint assignment of bus segment):
The number of the bus segment, via which the output is addressed, is entered here.
Depending on the SINUMERIK version, certain bus segments are preassigned.
• Local bus (similar to SINUMERIK FM NC, for example)
= 0
• 611D I/O bus (1st DCM, e.g., SINUMERIK 810D)
= 1
• Local I/O bus
= 2
• 611D I/O bus (2nd DCM)
= 3
• Reserved for virtual buses
= 4
• PROFIBUS-DP (NCU 573.2 and higher)
(PROFIBUS line for ProfiSafe at PLC end)
= 5
• PROFIBUS DP link module (NCU 573.2 and higher)
= 6
MD30110 $MA_CTRLOUT_MODULE_NR[n]
(setpoint assignment: Drive number/module number):
The number of the module in the bus segment, via which the output is to be addressed, is entered
here.
The logical drive number of the axis module can be set via machine data:
MD13010 $MN_DRIVE_LOGIC_NR[n]
for:
• SINUMERIK 810D
Range of values 0 - 15
• SINUMERIK 840D as 611 digital drive number
Range of values 0 -31
• SINUMERIK 840D PROFIBUS on link module
Range of values 0 -125
MD30120 $MA_CTRLOUT_NR[n])
(setpoint assignment: Setpoint output on drive module/module):
The number of the setpoint output must be entered here
(always output 1 for SINUMERIK 840D/810D).
MD30130 $MA_CTRLOUT_TYPE[n] (setpoint output type):
The speed setpoint output type is entered here.
0: Simulation (HW not required)
1: Standard (differentiated via HW configuration)
2: Stepper motor and 3: FM module (for SINUMERIK FM NC only)
MD30134 IS_UNIPOLAR_OUTPUT[n] (setpoint output is unipolar):
The unipolar speed setpoint output works only in conjunction with PROFIBUS DP.
