Definition of the terms used in this catalog
Overview
1
Drive data
The term «drive data» always refers to rotational speed, acceleration as well as jerk limitation.
TF
Gear unit
Gear unit loading (M gear max.) [Nm]
…refers to the maximum permissible mechanical torque at a spindle rotational speed of 1min-1.
T1
EA
+ M
2
Feed torque (M feed) [Nm]
…refers to the available torque at a rotational speed of 1 min-1, corresponding to the maximum permissible gear
load. Depending on the motor used and/or duty cycle, however, it can be correspondingly lower.
MOT / KAB
WMS / CNC
T2
/ T3
Eccentric spindle load (sl eccentric) [Nm]
The excentric load catalog* corresponds
– to 0 Nm (standard load always centric) for EA and M rotary tables as well as dividing / indexing axes of T-type
rotary tables
– For T-type rotary tables, to the maximum torque which affects the tilting axis in the form of the intrinsic load of the
dividing / indexing axis as well as that of the cubic standard load. Please refer to the respective parameter list,
catalog values.
For T-type rotary tables, the excentric load usual* is identical to the gear load with sls. For an EA rotary table, this
torque is equal to the value resulting from the maximum excentric load when using a rotoFIX Alu with a standard
load. Please refer to the respective parameter list, usual values.
The excentric load max load* corresponds to the maximum mechanical torque which can still be transmitted without
any damage using the gear unit at a minimum rotational speed of approx. 10 min-1. Please refer to the respective
parameter list, max load values.
J
Standard
(cubic)
Center of
gravity
F
STUB (static
torque of unequal
burden) [Nm]
RFX/LFX
* For definitions, please refer to «Geometry / Integration» p. 85
Workpiece
clamping
F
Center of gravity shift without and with load. The
greater the red center of gravity, the greater is the
gear unit loading in the tilting axis. The blue arrow
shows the direction in which the center of gravity
moves from «without load» to «with load».

pL standard spindle load (sls = sl standard) pp. 76/77
[kg]
…refers to the pL spindle load defined as standard, derived from practice, covering approximately 90% of all
applications. All drive data and parameter lists are de
