Model Analysis | Decoding the SH140/30270 Configuration

1. SM70/60/020/P0/44/S1/B0 Series Designation: SH140

Represents the medium-to-large power range, with an estimated power output of 0.75kW–3kW.

2. Core Parameter Code: 30270

This code encompasses critical specifications such as speed, torque, and encoder resolution.
For example, it may indicate:

Rated speed: 3000 rpm
Rated torque: 2.7 Nm
(Actual values depend on the full parameter set.)

3. Configuration Fields: 0/1/00/00/00/00/00

These digits define additional options, including but not limited to:

Voltage level
Protection rating (e.g., IP65)
Communication protocol (e.g., EtherCAT, CANopen)
Functional add-ons (e.g., brakes, oil seals).

Adopt “reducing machine + frequency conversion special motor + encoder + frequency converter” to achieve precise control of stepless speed regulation at ultra-low speed. YP series frequency conversion special motor has good universality, and its installation size conforms to IEC standard, and it is interchangeable with general standard type motor.　　Inverter motor wiring　　R、S、T are inputs, U、V、W are outputs! If the motor needs to be frequency converted to operate at industrial frequency, the phase sequence of the frequency converted output U、V、W must be the same as the phase sequence of the industrial frequency input U、V、W!Principle of frequency conversion motor_Frequency conversion motor wiring　　The feedback line of the motor frequency converter is mainly as follows, R, S, T threeportsare respectivelythe input port of the power supply, the output port of the frequency converter is U, V, W these three kinds, they are connected to the motor respectively. When we turn on the frequency converter of the motor, we first connect the intermediate relay and the motor together to the control input common end, at this time the forward start, the normally open contact of the intermediate relay is powered because of the closing, at this time the motor is forward, ifcurrentloss, the motor will stop.
