Technical Data
1) Use circuit breaker, which disconnects the system all poles in error case.
2) With the regulated operating modes MULTI and SERVO 5 % are to be subtracted as control reserve.
3) Max. current before the OL2 function triggers (in operating mode MULTI and SERVO).
4) The voltage (3ph) at the motor is dependent on the series-connected units and on the control method.
5) Higher switching frequencies on request.
6) The output frequency is to be limited in such way that 1/10 of the switching frequency is not exceed-
ed. Units with higher max. output frequency are subject to export restrictions and are only available on
request.
7) Recommended minimum cross section of the motor line for rated power and a cable length of up to
100 m (CU).
8) Thisdataisonlyvalidforunitswithinternalbraketransistor(see"unitidentification").
9) The starting current is decreased below 50 % of the initial value in max.1 s.
Pre-charging contactor: We recommend e.g., DIL M25 or better DIL M(C) 25 (for capacitive load 14 kW
690 V AC3)
Rated current: 25 A @ AC3 @ 400 V (AC3 = max. 6 x starting current)
Imax
in
= 25 A * 6 = 150 A (at DIL M C 25 even 350 A; see data sheet)
That are 50 % current reserve to ensure an appropriate lifetime/ number of switch-on procedures.
10) Dependingontheselectedflowtemperatureandthevolumeflow(±2kW).
11) The details of the total power loss refer to both converters at rated operation.
12) Otherflowtemperaturesuponrequest.
The technical data are for 2/4-pole standard motors. With other pole numbers
the inverter must be dimensioned onto the motor rated current. Contact KEB
for special or medium frequency motors.
