Limit Switches
The drive has two limit inputs, the positive limit input and the negative limit input. When
wiring the limit switches it is essential to check that a positive direction command produces
motion towards the positive limit switch. If this is not the case, interchange the motor
connections to A+ and A- to reverse the motor direction.
