Separated suppressor diodes (D1 and D2, e.g. P6KE33A von STMicroelectronics) for U
P
and U
mot
in case of separated supply voltages.
If only one power supply is used (jumper between U
P
and U
mot
), one suppressor diode
(D1) is sufficient.

Pin assignment
NOTICE!
Incorrect polarity can cause irreparable damage to the electronics
Connect the motor in accordance with the pin assignment.
Motors with integrated SC have a 6-wire cable. Wire 1 is highlighted in red for all product
variants.
