KL9570 - Buffer Capacitor Terminal

Application example

Risk of injury through electric shock and damage to the device!
Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals!


The capacitor in the KL9570 compensates peaks in the supply voltage for the stepper motor/DC motor.
As soon as this supply voltage exceeds 55 V, the KL9570 activates the brake resistor Rchopper, which then uses up the braking energy fed back from the stepper motor / DC motor connected to the KL2541.
Application example
Several motors
A KL9570 Capacitor Terminal can condition the supply voltage for several motors.
Dimensioning of the brake resistor
The brake resistor Rchopper (typically 10 Ω) should be dimensioned such that it can handle the expected heat generation without damage!
