QUICK PARAMETER REFERENCE
- Interdependence among parameters: parameters that change the settings of
others when modified versus parameters that are automatically modified as a function of a
parameter setting (during start-up and/or normal operation)
Output Overcurrent/Short-Circuit
Power Supply Undervoltage/Phase Loss
Inverter Overtemperature/Pre-charge Circuit
Output Overload (I x t Function)
Valid for P202 = 4 (Vector with Encoder)
Error in the Copy Function
Dynamic Braking Resistor Overload
Motor or Encoder with Inverted Wires
(Self-Tuning) (Valid for P202 = 4)
Serial communication error
Long period at torque limitation
Internal DC Supply Undervoltage
E04 can be "Pre-charge Circuit Failure" only in the following models:
44 A/500-600 V and for all 500-690 V and
660-690 V models. E04 can also occur when signal with inverted polarity is applied
at analog inputs AI1/AI2. The E04 fault message can also occur in the models up to
130 A/ 200-230 V, 142 A/380-480 V and 63 A/500-600 V when the temperature at
the heatsink is lower than -10 ºC.
