Display
Value Meaning
ERROR set
39 It has been attempted to select a locked parameter set.
Programmed response “Error, restart after reset”.
ERROR phase failure
3
One phase of the input voltage is missing (ripple-detec-
tion)
ERROR safety
28
Error in a function that is monitored by the optional
safety module. See Safety Instructions Mat.No.
00G6N1F-0000.
The error „ERROR 28: safety“ can not be reset
with a digital input. The error can only be reset by
switching off and on of the frequency inverter.
ERROR overfrequency
61 Current frequency is above the permissible range.
ERROR overload
16
Overload error can only be reset at "no ERROR over-
load" if OL-counter reaches 0% again. Occurs, if the
overload is longer than the permissible time (see techni-
cal data).
• mechanical fault or overload in the application
• inverter not correctly dimensioned
• motor wrongly wired
• poor controller adjustment
ERROR overload 2
19
Occurs if the current for zero speed is exceeded (see
technical data in the power unit manual). The error can
only be reset if the cooling time has elapsed and "no ER-
ROR overload 2" is displayed.
ERROR overpotential
1
Voltage in the DC link circuit too high. Occurs if the DC
link voltage exceeds the permissible value. Causes:
• poor controller adjustment (overshooting)
• input voltage too high
• interference voltages at the input
• deceleration ramp too short
• braking resistor defective or too small
ERROR overcurrent
4
Occurs, if the specified peak current is exceeded. Caus-
es:
• acceleration ramps too short
• the load is too big at switched off acceleration stop and
switched off constant current limit
• short circuit at the output
• ground fault
• deceleration ramp too short
• motor cable too long
• EMC
• DC brake active at high power (see chapter brake
control)
