Technology Module TM StepDrive 1x24..48V/5A
MA 1303-A007 EN 54
7.1 Control Interface in the PM mode
The control interface is shown in a table in chapter 13. The address data in the example
refer to a configuration in which the module has been assigned input addresses from 0 to
11.
7.1.1 Control Value
Depending on the operating command, the control value is interpreted as the absolute tar-
get position for positioning or the distance to be moved relative to the target position, for
free travel as a frequency specification and as an offset for reference travel. (data type 32
Bit, DEZ+/-, address QD0)
7.1.2 Operating Command
A new command is transmitted to the module with this value (data type 8 Bit, DEZ, ad-
dress QB4). These are the permissible operating modes:
0. no function
1. move to absolute position (control value). The direction of positioning results from
the set point (control value) and actual value (current motor position).
2. drive a relative distance (control value). The direction of positioning is determined by
the sign of the control value.
3. reference search: The sign of the control value defines the direction in which the
search is started. The control bits "Referencing with offset" and "Referencing to ref-
erence sensor" also have an influence on the search sequence. See chapter 8.2.3.
4. free run with constant frequency (control value). The sign of the control value de-
fines the direction of the free movement.
5. set position counter to control value
6. motor stop
7. emergency stop
i
Modified frequency or ramp values are only processed after the motor stop. We
recommend changing driving parameters when the drive is at a standstill (excep-
tion: the run current can be changed during a movement).
i
With free run a frequency change during the run is possible, i.e. a new frequency
value is taken over directly.
