Characteristic torque and speed curves
Detailed information on characteristic curves can be found under:
Beckhoff motor curves
All data, with the exception of the voltage constant, are based on
40 °C ambient temperature and 100 K overtemperature of the wind-
ing. The data can have a tolerance of +/-10 %.
If a gear unit is attached the power may be reduced by up to 20 %.
The A-side flange is intended for heat dissipation. If a gear unit is at-
tached, the heat dissipation is interrupted and reduces the power of
the servo drive.
By default, the heat is dissipated via the A-flange into the machine
bed. Due to heating of the gear unit, this is not possible for thermal
reasons. This configuration leads to a reduction of the nominal out-
put.
4.1.1
Technical terms
This chapter provides information on various technical terms and
their meaning.
Standstill torque M
0
[Nm]
Torque, also referred to as starting torque, that the servo drive can
generate at standstill. It can be maintained indefinitely at a speed n
< 100 min
-1
and nominal ambient conditions.
Nominal torque M
n
[Nm]
The torque that the servo drive delivers when it is operated at nomi-
nal speed and nominal current. Can be output in continuous opera-
tion S1 for an unlimited period of time.
Standstill current I
0rms
[A]
Sinusoidal current RMS value. This is consumed at a speed of n <
100 min
-1
in order to generate the standstill torque.
Peak current / pulse current I
0max
[A]
Sinusoidal peak current RMS value. The configured peak current of
the servo drive used must be less or equal.
Torque constant K
Trms
[Nm/A]
Indication of the torque in Nm generated by the servo drive per am-
pere of standstill current. The following applies: M
0
= I
0
x K
T
