Some doubts

Hello,

I am using the motor controller SDC2130 and I\'m very happy with it. I want to ask some questions:

#1 To supply 24V to SDC2130 controler I am using a 1mm wire twisted. The distance to the battery is about 4 meters. Is it recommended to install a capacitor 10mF in lines SDC2130 VMOT and GND?

#2 I am using 24DC and 80W motors, this motors are very basic. This wire have about 30ctms. Must i use a 0.1uF ceramic capacitor for M1+M1- terminals ?

#3 Is it bad idea to use the same supply for powercontrol and for other electronic (e.g. one arduino board ) ?


Thanks,
