Kinetix 7000 Connector Data

Control Signal Specifications

This section provides specifications for the Kinetix 7000 drive input/output
(IOD), SERCOS, motor feedback (MF), auxiliary feedback (AF) and brake
(BC) connectors.

Digital Inputs (IOD Connector)

Two fast registration inputs and four other inputs are available for the machine
interface on the Kinetix 7000 drive. The drive supplies 24V DC @ 300 mA for
the purpose of registration, home, enable, over-travel positive, and over-travel
negative inputs. These are sinking inputs that require a sourcing device. A 24V
DC power and common connection is provided for each input.

Table 20 - Digital Input Specifications

24V I/O Power

The Kinetix 7000 drive provides 24V DC power @ 300 mA total for the
HW_Enable_Pwr, Home_Switch_Pwr, Pos_OverTravel_Pwr,
Neg_OverTravel_Pwr, Reg_1_Pwr, and Reg_2_Pwr inputs on the specific drive.
The supply is protected with an automatically reset fuse. A temperature versus
time curve automatically controls closing of the fuse.

A common mode choke filters the registration power connection. An additional
common mode choke is provided for the remaining inputs.
