Hi All,
I am using SC16A servo motor controller to drive 12 sets of servo motor (Tower Pro MG995) with Power supply of 5V & current limit 5A.
Sometimes I feel some of the servo motors are shaking whenever I change their rotation. If all the motors are not shaking, the total current consumption would be ~0.08A. When one of the motor is shaking, it might shoot up to ~0.3A.
Below are the specs of the motor:
Specification shown:
Control System: +Pulse Width Control 1500usec Neutral
Required Pulse: 3-5 Volt Peak to Peak Square Wave
Operating Voltage: 4.8-7.2 Volts

Operating Speed (6.0V): 0.19sec/60 degrees
Stall Torque (4.8V): 9kg.cm
Stall Torque (6.0V): 11kg.cm
Operating Angle: 45 Deg. one side pulse traveling 400usec
360 Modifiable: Yes

May I know what is the possible reason causing this? Should it be the motor driving overload? Anyone can support me about this?
