Error 07 (Oh-R): Brake Resistor Overheat; Error 09 (E.par): Invalid Parameter Setting; Error 10 (Ide-): Brake Chopper Internal Error - Bosch Rexroth VFC 610 Series Operating Instructions Manual

Brake Chopper

10.3.5 Error 07 (OH-r): Brake Resistor Overheat

Possible reason
Inappropriate type or bad heat of brake
resistor
temperature sensor of brake resistor
error
Inappropriate threshold setting of tem-
perature sensor of brake resistor
Inappropriate setting for duty cycle of
brake chopper

10.3.6 Error 09 (E.Par): Invalid Parameter Setting

Possible reason
Parameter setting invalid after parame-
ter copy

10.3.7 Error 10 (idE-): Brake Chopper Internal Error

Possible reason
Internal error
DOK-RCON04-VFC*BRAKE**-IT01-EN-P
Solution
Check power of brake resistor
●
Provide good heat condition
●
Check the feedback signal of the resistor's temperature sen-
sor
Adjust threshold of temperature sensor of brake resistor
Reduce the duty cycle accordingly
Solution
Initialize all parameters
