5.2.2 Setting the homing parameters
Information on homing to a reference switch
Note
Damage to components.
The slide may only move directly against a fixed stop if the
maximum permitted impact energy is not exceeded (im-
pact energy = 0.5 x mass x speed
2
).
• The permitted value can be found in the description for
your positioning axis.
• If necessary, reduce the speed at which movement to the
stop is made. The speed can amount to 0 % to 50 % of
the rated speed.
• When referencing to a stop, set the offset of the axis zero
point ≠ 0 (see chapter 5.2.4).
• Protect sensitive stops by limiting the motor current.
The positioning axis DMES-... can conduct a homing run with
the preset current limitation (150 %). The current limitation
need not be modified.
Current limitation When the max. motor current is reached and the motor is
stationary, the MTR-DCI will detect a stop. The maximum
motor current during homing can be specified as 10...200 %
of the rated motor current (see FCT help or CI object 66073
h ).
Note
– If the drive is arranged vertically, an increase in the
motor current may be necessary. If the motor current is
too low, homing cannot be carried out or the unit may
detect a stop incorrectly.
– The set required speed cannot be reached if current
limitation is too great.
