4.2.3 Digital Inputs
IN_Ax, IN_Bx, IN_Cx (P3.26-30, P3.31-35, P3.36-40)
The PositionServo 940 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 COM terminal, (ACOM, BCOM and CCOM). All inputs have
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 can be set up as an Enable input and input C3 can be used as a registration
input. Reference the 940 Programming Manual for more detail.
For the registration input (C3), the registration time is 3µs for an encoder and 7µs for
a resolver.
