The speed of the motor
does not match the
frequency. 1. Check to see that the maximum frequency has been entered correctly.
2. Check the rated speed of the motor and the reduction ratio of the gear.
3. Check to see if manual boost and current limit are set properly.
4. If PID control is used, check gain adjustments.
The parameters stored do
not match the values
entered. When the input voltage was switched off the entered values were transferred to
the power-failure safe EEPROM. Power-off time must be at least 6 sec.
No entries can be made. Check to see if the parameter protection is activated via a digital input setting of
15 {SFT}.
The electronic motor
protection (fault E05) is
triggered. 1. Check the manual boost setting to see if it is too high.
2. Check the electronic motor protection setting to make sure that it is correct.
