VS1MX Dynamic Braking Resistors
VS1MX Frame B and C drives include built-in braking transistors to aid in applications requiring the ability to stop rapidly.
The brake resistor must be mounted and secured in place. Two wires connect to the + and BR terminals on the power strip
of the size B or the larger enclosure. Refer to Table 4-1 for minimum brake resistor values if a value that is larger than the
stock resistor kit is required.
Catalog Number
VS1MX-R50W200
Volts
115VAC
230VAC
460VAC
When the standard brake resistor kit is used, set P-34=1.
This provides software thermal protection for the standard 200W brake resistor kit.
When special brake resistors are used, set P-34=2.
No software thermal protection is provided in this setting and an external thermal device is required to protect the resistor.
