4.2.4 Digital Inputs
IN_Ax, IN_Bx, IN_Cx (P3.26-30, P3.31-35, P3.36-40)
The PositionServo Drive has 12 optically isolated inputs. These inputs are compatible
with a 5 - 24V voltage source. No additional series resistors are needed for circuit
operation. The 12 inputs are segmented into three groups of 4, Inputs A1 - A4, Inputs
B1 - B4, and Inputs C1 - C4. Each group, (A, B and C) have their own corresponding
shared common, (ACOM, BCOM and CCOM). Each group or bank can be wired as
sinking or sourcing. Refer to wiring examples mb103 and mb104. All inputs have a
separate software adjustable de-bounce time. Some of the inputs can be set up as
Special Purpose Inputs. For example inputs A1 and A2 can be configured as limit inputs,
input A3 is always set up as an Enable input and input C3 can be used as a registration
input. Refer to the PositionServo Programming Manual (PM94P01) for more detail.
For the registration input (C3), the registration time is 3µs for an encoder and 7µs for
a resolver.
