Product description

The documented product data also list 8TP50. Additional values include a cooling-air requirement of 0.041 m³/s, a sound-pressure level of 48 dB(A), E-CU 3 x 10 for the DC-link connection, a 10 / 16 mm² motor connection and an auxiliary-current requirement of 1.5 A. The full type number distinguishes this model from 6SE7021-8TP50, 6SE7021-8TB20 and larger 25.5-A units. The MLFB specifies a 510 to 650 V DC link, a rated output of 7.5 kW and a rated output current of 17.5 A. Documented identifiers and values: 6SE7021-8TP70-Z; 510-650; 7.5 kW; 17.5 A; 28.0 A; 5 kHz; 0.300 kW; 135; 360; 260 mm; 8.9 kg; P2; 20.8 A; 48. For procurement, Siemens 6SE7021-8TP70-Z should match the rating plate and Siemens 6SE7021-8TP70-Z should remain linked to the 6SE70 record and its 17.5-A stock class. Siemens 6SE7021-8TP70-Z belongs to the SIMOVERT MASTERDRIVES Motion Control family and is a 6SE70 Compact-PLUS inverter in Booksize construction. Dimensions are 135 x 360 x 260 mm and weight is 8.9 kg. The combination of 7.5 kW, 17.5 A and 135-mm width identifies a defined Booksize replacement position in an existing MASTERDRIVES Motion Control drive group. Its P2 designation matters because several 17.5-A variants are visually and functionally close. Siemens selection data gives a short-time current of 28.0 A, a rated DC-link current of 20.8 A and power loss of 0.300 kW at 5 kHz. It is the relevant replacement where an installed system requires the P2 version in this current class. The documented value for Sub-series is Motion Control Compact-PLUS P2.
