Motors for 690 V Power Modules
For the 690 V Power Modules, induction motors are permissible in the range from 50
% … 150 % of the inverter power without any restrictions.
Note
Motors for inverter operation
Only use motors that are suitable for operation with inverters with a DC link.
For 690 V Power Modules, motors with a suitable insulation system for 690 V inverter operation
are required (e.g. PREMIUM).

Line voltage
● for systems according to IEC: 3-ph. AC 500 V … 690 V ± 10% (in operation -20% < 1 min)
● for systems according to UL 3-ph. AC 500 V … 600 V ± 10% (in operation -20% < 1 min)
filtered devices only with Slash Rating (600Y/347V AC)
Line supply configurations Grounded TN/TT line supplies or non-grounded IT line supplies
Permissible line supplies (Page 50)
Line impedance
No restrictions
Power factor λ
> 0.9
Output voltage
3-ph. AC 0 V … 0.95 x input voltage (max.)
Input frequency
50 Hz … 60 Hz, ± 3 Hz
Output frequency
0 … 550 Hz, depending on the control mode
Inrush current
< LO base load input current
Overvoltage category ac‐
cording to EN 61800-5-1
III for line supplies
Pulse frequency
2 kHz (factory setting), can be adjusted to 4 kHz
If you increase the pulse frequency, the inverter reduces the maximum output current.
Short-circuit current rating
(SCCR) and branch protec‐
tion
≤ 100 kA rms
Branch protection and short-circuit strength according to UL and IEC (
support.industry.siemens.com/cs/ww/en/view/109479152
Braking methods
DC braking, compound braking, dynamic braking with integrated braking chopper
Degree of protection ac‐
cording to EN 60529
IP20; must be installed in a control cabinet
Protection class according
to EN 61800-5-1
The inverters are devices with protection class I
Touch protection accord‐
ing to EN 50274
DGUV regulation 3 when used for the intended purpose
