3 Technical details and pin assignment
Voltage source
The operating or supply voltage supplies a battery, a transformer with rectification and filtering, or a
switching power supply.
Note
•
EMC: For a DC power supply line longer than 30 m or when using the motor on a DC bus, additional
interference-suppression and protection measures are necessary.
•
An EMI filter is to be inserted in the DC supply line as close as possible to the controller/motor.
•
Long data or supply lines are to be routed through ferrites.

Permissible operating voltage
The maximum operating voltage is 51.5 V DC. If the input voltage of the controller exceeds this
threshold value, the motor is switched off and an error triggered. Above 50.5 V, the integrated ballast
circuit (3 W power) is activated.
The minimum operating voltage is 10 V DC. If the input voltage of the controller falls below this
threshold value, the motor is switched off and an error triggered.
A charging capacitor of at least 4700 µF / 50 V (approx. 1000 µF per ampere rated current) must be
connected to the supply voltage to avoid exceeding the permissible operating voltage (e.g., during
braking).
