Fig. 2-5 Torque characteristic curve of a motor with torque characteristic that is highly dependent
upon speed
1: Torque decrease zone
n
red
: Speed above which reduced torque has to be assumed
n
max
: Maximum speed
M
max
: Max. torque
M
red
: Torque at n
max
(corresponds to creep acceleration)
Simulation of torque characteristic
For the purpose of simulating the torque characteristic of the motor characteristic curve, the
machine data:
MD35242 $MA_ACCEL_REDUCTION_TYPE =
characteristic
can be used to select various types of characteristic curve:
0 = Constant characteristic
1 = Hyperbolic characteristic
2 = Linear characteristic
