spg-20 servo stepper motor controller positive negative pulse generator speed regulation 20khz Deskripsi : Origin : Mainland China Type 1Control board Type 2Control board + PCB modulerack Type 3Control board + 10K potentiometer Type 4Control board potentiometer module rack characteristic Maximum 20Khz pulse frequency output Linear acceleration and deceleration curve Onboard speed potentiometer or use external speed potentiometer Adjustable acceleration and deceleration slope The deceleration slope can be set to 50 of the acceleration slope Output signal voltage: 5V Power range: DC 8-28V Can be installed on standard DIN or C45 rail module rack Instructions for use When the system is powered on, it will detect the resistance of the external speed control potentiometer port (ESPD) and the COM terminal. If it is greater than 15K, the system considers that the external speed control potentiometer is not connected and uses the internal speed control mode, otherwise the system automatically switches to the external speed control mode Internal speed control mode: the on-board potentiometer ISPD is used to set the frequency of the output pulse. External speed control mode: 10k potentiometer is recommended for external speed control potentiometer (less than 10k potentiometer can also be used, but the speed control range is narrowed). Principle of external speed regulation: Different resistance values between ESPD and COM ports, the controller outputs pulses of different frequencies. The larger the resistance value, the lower the frequency. When the resistance value is greater than 10k, it stops outputting pulses, so the potentiometer is adjusted. The pulse output can be complete Terimakasih sudah belanja di Toko kami.
