• Motor Connectors: • Attention: wrong pinning leads to damage to the pcb
• never pull the connectors during operation!
Phase (coil) A of the motor is wired to connectors PHA1 and PHA2, Phase (coil) B to PHB1 and PHB2.
• Electrical Reference Switch
The reference switch is connected to the pins „Ref_In“ and „GND“. Optionally a series resistance of
about 2.2kOhms can be inserted to match EMC demands. In general using an opener, i.e. a normally
closed switch is advisable. So broken cables can be detected. The reference input is equipped with a
Schmitt-trigger.
