5.2.2 Setting homing parameters
When homing to stop:
Caution
Damage to components.
The slide (or piston rod) may only move directly against
the fixed stop if the permitted impact energy is not ex-
ceeded (impact energy = 0.5 x mass x velocity
2
).
• The permitted value can be found in the manual for your
axis.
• If needed, reduce the speed at which homing is carried
out (see FCT plugin help).
• If necessary, limit the max. motor current during homing.
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 can be limited during homing (see FCT help or
CI object 6073
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.
