Hello, I\'m looking to purchase encoders to use with the SDC2150 controller operating two motors (both with encoders). I\'d like to be able to have optimal speed control along a full range of motor speeds up to 3,000 RPM in a tank steering configuration.
The datasheet on the controller gives 30,000 counts/s as max encoder input frequency. Is this for each encoder or for the combination (i.e. 15,000 each)? Would I max out this frequency, or leave a bit of room to avoid pushing the controller\'s limits and having buggy/unpredictable behavior?
For example with max speed of 3,000 RPM = 50 RPs (per second) and assuming 30,000 counts/s capability would result in a selection of 30,000/50 = 600 counts/revolution encoder.
Many thanks!
Keith
