Error 4 (Oe-1): Overvoltage At Constant Speed; Error 5 (Oe-2): Overvoltage During Acceleration; Error 6 (Oe-3): Overvoltage During Deceleration - Bosch Rexroth VFC 3210 Operating Instructions Manual

VFC 3210
Possible reason
Excessive overexcitation braking factor Reduce [E0.55]
Wrong motor parameter setting

13.4.4 Error 4 (OE-1): Overvoltage at Constant Speed

Possible reason
Surge voltage from power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Excessive load rotation inertia
Noise interference

13.4.5 Error 5 (OE-2): Overvoltage during Acceleration

Possible reason
Surge voltage from power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Direct start during motor running
Excessively short acceleration time

13.4.6 Error 6 (OE-3): Overvoltage during Deceleration

Possible reason
Surge voltage from power supply
Motor to earth short circuit causes
DC-bus capacitors overcharged
Excessive load rotation inertia
Excessively short deceleration time
Wrong wiring of brake resistor
The brake chopper is damaged
DOK-RCON04-VFC3210****-IT01-EN-P
Solution
Correct motor parameters setting
Solution
Check input power supply
Check motor connection
Use suitable brake components
Check wiring of control circuit, main circuit and grounding
Solution
Check input power supply
Check motor connection
Restart after motor stop or start with speed capture (E0.35)
Increase acceleration time (E0.26) or use S-curve (E0.25,
E0.28, E0.29)
Solution
Check input power supply
Check motor connection
Use suitable brake components
● Increase deceleration time (E0.27)
● Use a brake resistor or a brake resistor unit
● Enable stall overvoltage prevention during deceleration
(C0.25)
Check the wiring of brake resistor
