Input P9.00 to P9.04 properly in accordance with the motor nameplate; set the basic running
frequency P0.15, maximum output frequency P0.11 and maximum output voltage P0.12; set the
acceleration time and deceleration time P0.08 and P0.09 properly.
Setting P9.15 to 1 perform auto−tuning. Press the run key to start the parameter auto−tuning,
and P9.15 will be restored to 0 automatically upon completion of auto−tuning process.
Note:
Make sure that the motor is in the standstill status when starting the parameter auto−tuning. If
there is over current or over voltage failure during the auto−tuning process, it can prolong the
acceleration/deceleration time P0.08 and P0.09 properly.
If the inverter power does not match the motor power, select static auto−tuning. After the tuning,
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 directly.
During the process of parameter auto−tuning, "−At−"will appear on the operation panel.
P9.16
P9.17
P9.18
This function can be used to protect the motor.
The unit's place of P9.16 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 allowable motor overload time determined by P9.18. Once the
accumulated overload time is reached, the inverter will report "E.oL2" motor overload failure.
When the load type is constant torque (P9.00=0), the motor overload protection time P9.18 corresponds
to the overload protection time under 150% rated load current and is 10 minutes by factory default; when
the load type is variable torque (P9.00=1), the motor overload protection time P9.18 corresponds to the
overload protection time under 115% of rated load current and is 10 minutes by factory default.
Note: The calculation of motor overload protection continues during the inverter running and stopping
process, while the accumulated overload value will be reset when the inverter is power−off.
