5 volts for the controller: Regulated power supply
4,8-6 Volts for the servo’s: This is also a regulated power supply with current limmitter display
The behavior is the same in both servo’s and choosing a different channel of the controller also makes no difference. As soon as the channel is activated the servo starts moving out of control.
I looked at the signals from the controller using a oscilloscope. When no servo’s are connected, the pulses look fine. When I connect a servo, the pulses are malformed and allot of noise is added.
It looks like the servo’s are putting load and/or noise on the signal lines.
How can I avoid this?
I suspect that the problem is with the power supply; can you try a battery pack for the servos? Regulated supplies often aren’t up to the task of delivering power to motors.
That’s going to be a problem. I do not have a battery pack. I’ll try to build one in the next days.
The power supply I use can supply 3 amp’s continuously and 5 amp’s peak.
Finally I got round to trying your suggestion. Guess what. It worked
I’ve got 6 (older) penlite cell’s in a holder en connected it to the servo. Everything went perfectly.
