Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/370/P0/45/M1/B1 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).

The control accuracy of the AC servo motor is guaranteed by the rotary encoder at the rear end of the motor shaft. Taking the Panasonic full digital AC servo motor as an example, for the motor with a standard 2500-line encoder, since the four-time frequency technology is used inside the driver, its pulse equivalent is 360°/10000=0.036°. For the motor with a 17-bit encoder, the driver rotates one circle for each 217=131072 received pulses, that is, its pulse equivalent is 360°/131072=9.89 seconds. It is 1/655 of the pulse equivalent of the stepping motor with a step angle of 1.8°.Two, different low frequency characteristicsStepper motors are prone to low-frequency vibration at low speeds. The vibration frequency is related to the load condition and the performance of the driver, and it is generally believed that the vibration frequency is half of the motor”s no-load starting frequency. This low-frequency vibration phenomenon, determined by the working principle of the stepper motor, is very disadvantageous to the normal operation of the machine. When the stepper motor operates at low speed, it is generally necessary to use damping technology to overcome the low-frequency vibration phenomenon, such as adding a damper to the motor or using the microstepping technology on the driver, etc.
