I have my hexabot walking fine but the servos tend to overheat after about 10 minutes. Is there a command that stops the flow of current to the servos so they can cool off? This avoids me disconnecting the battery each time.
Thanks,
Bill
Hi Bill,
For most servos, this is done by changing the RC PWM signal to either a “low” or a “high” signal (i.e.: stop sending pulses). This can be achieved on any SSC-32U channel by sending either a position of 65535 (high) or 0 (low).
In truth, these two outputs are typically used to create digital outputs from the SSC-32U, but they also servo to stop the RC PWM output from a channel, which makes more RC servomotors cutoff power to their motors / make them idle.
You can read more about the commands of the SSC-32U in the user manual, pages 24-26.
We hope this helps!
Sincerely,
Thanks that is what I read in the document but it said not to do it on standard RC Servos. I have the HS-422 servo, not sure if that is a standard servo. The doc says:
Discrete Output
The IO pins on the SSC32 can be used to provide HIGH (5V) or LOW (0V) signals. Note that
you should NOT use this function with standard RC servos.
… #
● : Channel number in decimal, 031
● <|v|>: Logic level for the channel, either ‘H’ for High or ‘L’ for Low
● : Carriage return character, ASCII 13
The outputs on the SSC32 come from four 8 bit shift register chips. There are four banks of 8
bit outputs as shown 07, 815, 1623 and 2432. The outputs can sink or source up to 20mA
per output pin, but a max of 70mA per bank must be observed. The channel will go to the
level indicated within 20mS of receiving the carriage return.
Example: #3H #4L
This example will output a High (+5v) on channel 3 and a Low (0v) on channel 4.
Hi,
We recommend trying out a simple “position = 0” command with one RC servomotor and see how it goes. If the test is conclusive (i.e.: the servomotor stops moving and does not do anything “weird”), then it should be ok for your set of servomotors.
ex:
#0P0Let us know if it works for you.
Sincerely,
