Dynamixel-P H42P-020-S300-R: an RS-485 servo that’s both compact and powerful
Like with all the Dynamixel-P and Dynamixel-P actuators in the R series, the Dynamixel-P H42P-020-S300-R model is an all-in-one servo equipped with an RS-485 multidrop communication bus.
It offers 5 operational control modes including extended position control and PWM control, which proves very useful if you want to control the accelerations and decelerations of a mobile robot. Less powerful than 100 or 200 W servos, this actuator still offers excellent torque, precision and speed. You’ll benefit from a resolution equivalent to 607,500 pulses per revolution and a reduction ratio of more than 300:1. Being efficient does not compromise the servo’s compactness: at just over 300 g, it can be installed under various configurations on your robotised systems.
A worthy representative of the Dynamixel-P range
The new Dynamixel-P series is a major improvement on legacy Dynamixel servo motors, particularly in terms of reliability and resolution. All servos in this range allow for a high precision of movement, at a reduced response time. Heat and noise levels have also been improved.
The servos have been redesigned, notably with the addition of JST connectors. The enhanced control table, fully programmable, now support all X-series functions.

Resources for the Dynamixel H42P-020-S300-R servo
Review the full characteristics of the Dynamixel-P H42P-020-S300-R servo in the resources below:
Check that your Dynamixel servomotor is correctly configured. Do not hesitate to re-flash it with the ROBOTIS Software Roboplus. After re-flash remember to re-configure it. If the issue is not solved, contact us for an advanced support.
The motor is probably not well mounted. Check that you correctly mounted the horns by respecting the mark.
Check your power supply and the system cabling (try with a different servomotor). You can also reset the servo. If nothing works, the best solution is to go through the Dynamixel servomotor checklist!
The 1.0 protocol is specific to the Dynamixel AX and MX series. Protocol 2.0 has been developed with the new X series and Dynamixel Pro. Protocol 2.0 control tables include PID controls for extremely precise adjustment of servo movements. The firmware of the MX series servos can be upgraded to use protocol 2.0. You can refer to the protocol 1.0 and protocol 2.0 pages for more information.
