SIEMENS 1PH7 series asynchronous motors for machine tools

²；Example: When U-original=425V, P-original=22.6kW (6000rpm), and U-new=380V,new².

2. Encoder configuration

According to whether it comes with DRIVE CLiQ interface, the corresponding relationship between encoder type and order number is shown in the following table:

Interface type, encoder type, order number, 9th digit, core parameter

No DRIVE CLiQ, no encoder A-

No DRIVE CLiQ incremental encoder (sin/cos 1Vpp, with C/D signal) M 2048 S/R, 1 reference pulse per revolution

No DRIVE CLiQ absolute encoder (EnDat) E single turn 2048 S/R, multi turn 4096 rpm

Equipped with DRIVE CLiQ incremental encoder (22 bits, with commutation position), D resolution 4194304, built-in 2048 pulses/rev

Equipped with DRIVE CLiQ absolute value encoder (22 bit single turn+12 bit multi turn) F operating range of 4096 revolutions, suitable for high-precision positioning

Selection and installation specifications

1. Selection tools and processes

Core tool: SIZER software (order number 6SL3070-0AA00-0AG0), supporting steps:

Define driving tasks (such as spindle/feed drive);

Input load parameters (torque, speed, cycle time);

Match motor model (output power/torque curve);

Select the driving components (power module, motor module);

Generate selection report (including component list and dimension diagram);

Auxiliary tools: STARTER (debugging software), SinuCom (fault diagnosis).

2. Installation and operation restrictions

Installation position: Supports horizontal (IM B3) and vertical (IM V1/V3), axial force needs to be recalculated when extending upwards/downwards;

Concentricity requirements: Radial runout tolerance R level (0.025mm for AH100-132, 0.03mm for AH160-225), flange coaxiality tolerance R level (0.05mm for AH100);

Vibration control: vibration speed ≤ 2.8mm/s (level A), vibration level SR should be selected for exceeding the rated speed;

Wiring specifications: Power cables should avoid stretching/damage, DRIVE CLiQ interfaces should be anti-static (ESD protection), and external fan cables should be wired independently.
