Stepnet Module DevKit • For Rev 4 PC boards TDK Provides Mounting & Connections for Stepnet Module CANopen Stepping Motor Driver FEATURES • Develop & Debug Stepnet projects then transfer design to OEM pc board. MODEL DRIVER Ic Ip VDC TDK-075-01 STM-075-07 5 7 75 DESCRIPTION The Development Kit is a companion product to Copley Controls’ new Stepnet Module stepping motor driver. It provides mechanical mounting and electrical connections for the driver so users can quickly connect Stepnet and begin to develop applications. Euro style screw-terminal connector blocks simplify connections for power and motor phase-windings. SubD connectors have compatible pinouts with Accelus™ and Accelnet™ panel amplifiers for command, I/O and optional motor encoder signals. A 16-position rotary switch connects to Stepnet I/O pins for selection of the CAN bus device address. Individual toggle switches are wired to other I/O pins to simulate limit switches, motor overtemperature sensor, and home switch functions. Jumpers permit these switches to be disconnected so that the I/O pins can connect to user equipment through the Sub-D connectors. A 121Ω resistor can be jumpered in or out as a terminator for the CAN bus signals if the development kit is the last device on a CAN bus. Four LED’s can be jumpered in or out to the Stepnet logic outputs. These give an easy read-out of the output status for debugging. Motor encoder signals are connected through from the motor connector to the signal connector eliminating split cables in cases where the Stepnet is operating as a stand-alone servo-motor control. In these cases, the external controller uses the encoder for position feedback, and Stepnet operates the stepping motor as a DC brushless motor.

Stepnet Module DevKit For Rev 4 PC boards TDK RS-232 CONNECTION The RS-232 port is used to configure Stepnet for stand-alone applications, or for configuration before it is installed into a CANopen network. CME 2™ software communicates with Stepnet over this link and is then used for complete amplifier setup. The CAN address that is set by the rotary switch can be monitored, and an address offset programmed as well. This will add to the switch address to produce a working CAN address that can be from 1 to 127. The RS-232 connector, J4, is a modular type that uses a 6-position plug, four...

For Rev 4 PC boards Stepnet Module DevKit TDK LOGIC INPUTS Stepnet has twelve logic inputs. [IN1] is dedicated to the amplifier enable function, the other inputs are programmable. The chart below shows the placement of jumpers to connect logic inputs to switches on the development kit, or to external signals via signal connector J3: LOGIC OUTPUTS Stepnet has four logic outputs that can drive controller logic inputs or relays. If relays are driven, then flyback diodes must be connected across their terminals to clamp overvoltages that occur when the inductance of the relay coil is suddenly...

Stepnet Module DevKit ENCODER CONNECTIONS TDK POWER SUPPLIES The development kit has a 26C32A differential line receiver for the motor encoder inputs. Differential-output encoders are preferred for best signal quality and noise rejection. Wiring should be twisted-pairs, preferably with a shield for each pair. To eliminate noise on the encoder signals caused by reflections on the cables, it is good practice to terminate signal-pairs with a resistor that matches the characteristic impedance of the cable. On the development kit,121Ω resistors are provided for this purpose. Jumpers at JP9-A, B,...
