The homing is made on the FTI interrupt (refer to §4.2 for more information). The home switch and limit switch
are tested at each FTI. As the DSCDM does not have a DIN2 (which is normally used for home switch), bit# 2
and 3 of parameter K58 allows the user to select DIN1 or DIN9 to connect the home switch (refer to §12.9
for
more information). It is not possible to make a homing on mechanical end stops as there is no way to detect
them.
• Reference mode
With stepper in open loop, the reference mode (defined by parameter K61) which can be used are:
• Standard reference mode: K61=1 (refer to §12.6
for more information)
Remark: The regulation loop principle is identical with a three-phase stepper motor.
• Speed reference mode: K61=3 (refer to §13.2.1
for more information)
Remark: The regulation loop principle is identical with a three-phase stepper motor.
