Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/120/P0/44/R1/B0/01 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).

　During the entire process of wiring the motor frequency converter, of course, the setting of the frequency converter parameters is indispensable. We need to set the frequency of the frequency converter and the operation mode. In addition to these basic settings, we also need to set the maximum frequency of the current and the basic frequency. The rated voltage and the maximum output voltage and related time can be changed at the same time. Finally, there are some functions such as data protection, function code LCE monitoring, starting frequency holding time, etc. that can be set later according to the type of frequency converter of different manufacturers.Principle of frequency conversion motor_Frequency conversion motor wiring　　＊1 There is wiring protection at the input side ( primary side ) of the frequency converter, so please install a circuit breaker (MCCB) or residual current device (RCD) (with overcurrent protection function) recommended for each frequency converter. Do not use a circuit breaker with a rated power above the recommended power.
