KEB COMBIVERT F6 - Connection of a Braking Resistor

6.7 Connection of a braking resistor
CAUTION
Braking resistors dissipate the produced energy of the motor into
heat during generatoric operation.
Burns and re risk due to high surface temperatures.
► Payattentiontoappropriateprotectionagainstcontactandre.
► The mains voltage must always be switched off in case of a defec-
tivebrakingtransistor(rerisk).
► Ifdirectcontactcannotbeavoidedduetostructuralreasons,afx
the warning "Hot surfaces".
DANGER
Regenerative operation
Risk of death due to electric shock!
The drive converter remains in operation in spite of switched off power
supply in regenerative operation.
► An error must be released by external wiring which switches the
modulation off in the drive converter. This can occur e.g. at termi-
nals T1 / T2 or via digital input.
► The drive converter must be programmed accordingly in each case.
The use of a KEB regenerative unit is reasonable for applications which produce
a lot of regenerative energy. Regeneration of excess energy into the mains.
