Maximum target position selection (C4265)
The maximum target position selection results from the possible traversing range of
16384 position encoder revolutions converted into real units.

C4265 is limited to
±214000.0000 units.
Position resolution (C4266)
Number of increments per unit specified
ƒ Due to the internal remainder considered, the lowest−order position can vary about
1.
ƒ 1 revolution of position encoder ¢ 65536 increments.
ƒ Value range: 0 ... 2140000000
Maximum traversing speed (C1240)
Via C1240 you can define the maximum traversing speed (v
max
) for the machine. The
speed specifications in the positioning profiles are limited internally to v
max
. v
max
should
be set lower than the velocity possible at maximum motor speed (C0011). The value can
be calculated according to the following formula:
C1240

Tip!
The maximum input value for v
max
can be read out via C3060.
Maximum acceleration/deceleration (C1250)
The maximum permissible acceleration or deceleration for positioning processes among
other things depends on the motor torque and the moment of inertia of the entire
mechanics driven during the positioning process.
