Rexroth HVR / HVE power Supply Fault codes

bbREADY FOR POWER ON
Supply and drives are fault-free. Power can be switched on.
LbPOWER OK
Mains contactor is ON. DC bus voltage within permissible range.
14EXTERNAL COMPONENT WARNING
WARNING an auxiliary unit is being applied. Power off in 30 s.
15CONTROL VOLTAGE TEMP. WARNING
Control voltage supply is overloaded. The temperature pre-warning contact has opened.
16SOFTSTART-FAULT
DC bus cannot be loaded.
17POWER OFF WITH BUS SHORTING
Power is off and DC bus dynamic brake activated.
18HEATSINK OVERTEMP. FAULT
Power off due to excessive heatsink temperature.
20BLEEDER OVERLOAD
Rotary drive energy (HVR/HVE) or regenerated power (HVE) too high.
23DRIVE FAULT
Power of due to drive error.
24EXTERNAL COMPONENT ERROR
Power off due to fault in auxiliary unit (bleeder, loading device).
25REGEN. POWER OVERLOAD
Continuous regenerated power of the drives excessive.
26BUS POWER OVERLOAD
The continuous feed in power of the drive excessive.
50HEATSINK TEMP. WARNING
Temperature pre-warning contact is open. Power off in 30 s
52BLEEDER OVERLOAD WARNING
80 % of the allowable bleeder ON time has been achieved due to excessive regenerated power.
