10.8 Brake Resistor Ratings
10.8.1 Brake Resistor Ratings
NOTICE
The brake resistor function is available for the VACON
®
100 INDUSTRIAL.
For brake resistor rating tables, see:
•
10.8.5 Brake Resistance and Brake Power, Mains Voltage 208–240 V
•
10.8.6 Brake Resistance and Brake Power, Mains Voltage 380–500 V
•
10.8.7 Brake Resistance and Brake Power, Mains Voltage 525–600 V
•
10.8.8 Brake Resistance and Brake Power, Mains Voltage 525–690 V
10.8.2 Brake Resistance in Light duty and Heavy Duty
Make sure that the resistance is higher than the set minimum resistance. The power handling capacity must be sufficient for the
application.
The light duty cycle is for brake resistor cyclic use (1 LD pulse in a 120-second period). The light duty resistor is rated for a 5-second
ramp from full power to 0.
The heavy duty cycle is for brake resistor cyclic use (1 HD pulse in a 120-second period). The heavy duty resistor is rated for a 3-second
full power braking with a 7-second ramp to 0.
