9 Technical data
9.9.4 Voltage limit curves
1 S1 Switch-on time 100 % (100 K)
2 S2 - S10 On-off-switch < 100 %
3 Field weakening range
Characteristic line explanation:
M: Torque
M
F
: Torque for external ventilation
M
W
: Torque for water cooling
M
max
: Maximum torque
M
lim
: Voltage limit characteristic line
(torque limit without field weakening,
e. g. for n
N
= 3000 min -1 )
M
limFW
: Voltage limit characteristic
line (torque limit with field weakening,
e. g. for n
N
= 3000 min -1 )
The progression of these limit curves depends on a combination of the winding ver-
sions (K
EM
factors) and the intermediate circuit voltage ends of the respective servo
inverter.
