4.1.3 Operating Time
Operating mode S3 is supplemented by specification of the ON time (ED) in %.
The operating time is calculated as follows:
ED Cyclic duration factor in %
ΔtP Operating time with constant load
Fig.4-2: Cyclic duration factor
The values specified in the documentation have been determined on the basis
of the following parameters:
Cycle duration: 10 min
Cyclic duration factor (ED): 25%
4.1.4 Dimension Sheet Specifications
The permanent shaft load on the motor output shaft at speed n≈0. The different
operating modes are indicated by the following indices:
M
0_60
Continuous torque at standstill, 60K
M
0_100
Continuous torque at standstill, 100K
M
0_S
Standstill continuous torque surface
M
0_L
Continuous torque at standstill, liquid
For the continuous torque at standstill M
0
necessary phase current (effective
value) of the motor at a speed of n≈0. The various operating modes are indi-
cated by the following indices.
I
0_60(eff)
Continuous current at standstill, 60K
I
0_100(eff)
Continuous current at standstill, 100K
Standstill continuous torque
Continuous stand-still current
