7.3 FAQ

Ⅰ. Why have abnormal operation?
(T) Check if motor data identification has been performed. For details, refer to the parameter of P9.T5
(T) For E5−H series, check if the lines for Hall sensor is loosen or dislocated for E5−H−4TT8.5GA and
above power class, for E5−A series, check if the lines for Hall sensor is loosen or dislocated for
E5−A−4TTT and above power class.
Ⅱ. Why the running frequency kept at 0Hz when run reverse ?
(T) Check if the frequency is set to 0
(T) Check if the parameter value of P3.09 is set to 0. If not, change it to 0.
. Why the braking resistor didn't it work?
Ⅲ
(T) Check if the braking resistor is connected between the main circuit terminals BT and BT
(T) Check if the parameter value of PA.09 is set to T. If not, change it to T
. Why there is large deviation between the analog input and the setting frequency?
Ⅳ
(T) Check if the analog input type is correct and the jumpers of control board for select 0~T0V or 0~T0mA
are properly set. For the analog voltage input, the jumper turn to V side and for the analog current input,
the jumper turn to I side
(T) Check if the analog input curve is properly set, for details, refer to parameters of P6.00 to P6.T0
Ⅴ. Why there is large deviation between the analog output and the running frequency?
(T) Check if the analog output type is correct and the jumpers of control board for select 0~T0V or 0~T0mA
are properly set. For the analog voltage output, the jumper turn to V side and for the analog current
output, the jumper turn to I side
(T) Check if the analog output curve is properly set, for details, refer to parameters of P7.05 to P7.09
. Why report E.AIF analog input abnormal error?
Ⅵ
(T) Check if the analog input type is correct and the jumpers of control board for select 0~T0V or 0~T0mA
are properly set. For the analog voltage input, the jumper turn to V side and for the analog current input,
the jumper turn to I side
(T) Check if the analog input voltage exceeds TTV
(3) When the analog power supply is inner +T0V of the control board, check if the voltage of +T0V is lower
than 9V or higher than TTV. If yes, check if the resistance value between the +T0V and the GND is less
than TKΩ after powered off completely
. Why report E.P10 abnormal error?
Ⅶ
(T) Check if the voltage of +T0V on the control board is lower than 9V or higher than TTV. If yes, check if the
resistance value between +T0V and GND is less than TKΩ after power off completely
