E5 Series High Performance Universal Inverter
is in the standstill status when starting data identification. If there is over current or over voltage fault
during the data identification process, it can prolong the accelerationTdeceleration time P0.08 and
P0.09 properly.
 If the inverter power does not match the motor power, motor data identification at standstill should be
selected. Before identification, manually change the no-load current P9.05 to about 40% of the motor
rated current P9.04.
 If the motor parameters are given, please enter the parameters to P9.05 ~ P9.09 directly. If the motor
parameters are not given, please execute the motor data identification. The magnetic flux saturation
coefficient value in P9.T0 ~ P.T4 is automatically set after motor data identification, eliminating the
need of setting by the user.
 During the process of motor data identification, "−At−" will appear on the operation panel.
P9.T6
P9.T7
P9.T8
This function can be used to protect the motor.
The ones place of P9.T6 determines whether the motor overload protection is to be executed and
whether the motor overload protection employs current mode or sensor mode.
0: Motor current mode: Overload is calculated in accordance with motor current, running frequency and
running time and compared with the motor overload protection time determined by P9.T8. Once the
accumulated overload time is reached, the inverter will report "E.oLT" motor overload fault.
Note:
The time calculation for overload protection continues during running and stop status, the value will be
reset after power off.
