REXROTH EFC 3610 Series User Manual

Possible reason Solution
Motor power and frequency converter
power do not match
Motor power has to match with frequency converter power
Excessive overexcitation braking factor Reduce [E0.55]
Wrong motor parameter setting Correct motor parameters setting
13.4.4 Error 4 (OE-1): Overvoltage at Constant Speed
Possible reason Solution
Surge voltage from power supply Check input power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Check motor connection
Excessive load rotation inertia Use suitable brake components
Noise interference Check wiring of control circuit, main circuit and grounding
13.4.5 Error 5 (OE-2): Overvoltage during Acceleration
Possible reason Solution
Surge voltage from power supply Check input power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Check motor connection
Direct start during motor running Restart after motor stop or start with speed capture (E0.35)
Excessively short acceleration time
Increase acceleration time (E0.26) or use S-curve (E0.25,
E0.28, E0.29)
13.4.6 Error 6 (OE-3): Overvoltage during Deceleration
Possible reason Solution
Surge voltage from power supply Check input power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Check motor connection
Excessive load rotation inertia Use suitable brake components
Excessively short deceleration time
● Increase deceleration time (E0.27)
● Use a brake resistor or a brake resistor unit
● Enable stall overvoltage prevention during decelera-
tion (C0.25)
Wrong wiring of brake resistor Check the wiring of brake resistor
The brake chopper is damaged Contact with service
