Coreless motor and metal gear TTL command type
The TTL command servo was developed in response to customer requests for a servo with the same PWM format as an RS301CR servo. It can also be controlled with conventional R/C servo PWM signals, allowing it to be controlled with radio control receivers and third-party PWM servo control boards. By retaining its command functionality, it can now be controlled with both serial communication using TTL-level signals and PWM signals. The control format automatically switches based on the first received format after power-on, eliminating the need for setting changes to match the connected device. While it is less susceptible to noise than RS485 command servos and has a maximum command connection limit of 26, it offers features that make it more than just a budget-friendly option, such as a “Warm Up Time” that prevents sudden operation when starting up with PWM.
