Connection Of A Braking Resistor With Temperature Monitoring In Accordance With Ul; Encoder Interface Connection; Resolver Connection At Keb Motors With Connector X3A - KEB COMBIVERT F5 Servo Installation Manual

3.3.6 Connection of a braking resistor with temperature monitoring in accordance with UL

• PA, PB Connection for braking resistor
• Technical data (see chapter 2.3)
• During clearing of the temperature monitoring the input voltage is switched off
• for additional protection in regenerative operation connect the auxiliary contacts 11
and 12 of the line contactor K1 (see 3.3.5)
With input rated voltage of
480 Vac no braking resistor shall
be connected.
Braking resistors can develop very high surface temperatures, therefor install as safe-to-
touch as possible !
3.4

Encoder interface connection

The plugs may only be connected / disconnected when the inverter and supply voltage are
disconnected !
