WARNING – Serious injury from electric shock!
If the APS module is not operated with SELV/PELV voltages, the risk of
dangerous voltages may be on the device. Touching these components
carrying high voltages can cause serious injury or death from electric shock:
- Always observe the safety concept SELV / PELV to ensure safe
insulation and separation of low voltage supplies from the mains.
WARNING – Serious injury from electric shock!
During electrical installation cables, connectors, etc. can be live.
- Before starting wiring, make sure that none of the power supplies are
connected to the primary side of the mains supply. Isolate the power
supplies from the mains or remove the appropriate fuses.
- The APS module must be plugged into the EVA-APS board before
installation.
- Do not plug or unplug the modules while powered.
- Do not plug or unplug the connectors while powered.
- If the equipment was energised, wait 3 minutes after power off to allow
the capacitors to discharge and ensure that there are no residual
charges on cables, connectors and boards

Power supply voltage:
The APS supply (24 – 70 V) is not connected to the Arduino supply.
APS Arduino Shield requires its own power supply to supply the APS power
stage!
The Arduino is not supplied by the APS supply (24-70 V).There is no
electrical isolation of the supplies.
Please note the Arduino manual for the power supply of the Arduino board!

CAUTION – Possible damage!
The module is designed for a maximum supply voltage of 70 VDC. If it is
supplied with >70 VDC the card might be damaged.
- Make sure that a power supply is used with less than 70 VDC to avoid
damage.
Before integrating or changing the APS module always make sure that the APS-Arduino
shield is shut down and the power supply is disconnected.
WARNING – Serious injury from electric shock!
During electrical installation cables, connectors, etc. can be live.
- Before starting wiring, make sure that none of the power supplies are
connected to the primary side of the mains supply. Isolate the power
supplies from the mains or remove the appropriate fuses.
- Do not plug or unplug the modules while powered.
- Do not plug or unplug the connectors while powered.
- If the equipment was energised, wait 3 minutes after power off to
allow the capacitors to discharge and ensure that there are no
residual charges on cables, connectors and boards.
Now you can start with the electrical installation.

6.2 Electrical Installation
Ensure sufficient bending radius of the cables during installation. Do not lay the cables in
tension or bend them.
If all the connections are made, the last step is to plug in the power supply to the mains.

Wiring Schemes
Stepper motors with 0.1 to 5 APEAK phase current can be controlled at a maximum of 70
VDC with the APS module Arduino shield.
Fig.6 Connection diagrams for 4,(6) and 8 lead stepper motors
Stepper motors with 8 leads can be connected with the windings wired in parallel (1) or
series (2).

phytron
19 MA 2120-A002 EN
For 6 lead stepper motors, wiring scheme (3) with series windings is recommended.
If wiring scheme (3) cannot be used because of the motor construction, the motor may be
operated with only two of the four windings energized according to wiring scheme (5).

CAUTION – Possible damage!
Destruction of the power stage by connecting a 5 phase stepper motor.
- Do not connect any 5 phase stepper motors to avoid damage.

7 Commissioning
Please follow the described order when you put into service the evaluation board:
1. Plug the APS power stage onto the socket connectors of the APS-Arduino shield.
2. Plug the shield onto the Arduino board.
3. Screw the wire ends of the motor cable to the 4-pin socket.
4. Screw the wire ends of the supply cable to the 2-pin socket.
5. Connect the PC via USB cable.
6. Power on.
7. Parameterise the APS power stage via SPI Interface and Arduino software.
i
CAUTION – Possible damage!
Some modules are set to a default value on delivery. So e.g., the motor
current must be set to the corresponding value (see the motor data from
the motor manufacturer). Connected components like motors can be
damaged by incorrectly set values.
- Please check if the parameters are correct before starting.
