5.2.2 Setting the reference travel parameters
Notes on referencing to the stop
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 manual 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.
• During referencing to the stop, set the offset of the axis
zero point
≠ 0 (see chapter 5.2.4).
• Protect sensitive stops by limiting the motor current.
Positioning axis DMES-... can carry out reference travel with
the factory-set current limitation (150 %). The current limita-
tion need not be revised here.
Current limitation The MTR-DCI recognizes a stop when the maximum motor
current is reached at the same time as the motor is at a
standstill. The maximum motor current during reference
travel can be specified with 10 ... 200 % of the rated motor
current (see help for the FCT or CI object 6073
h ).
