 PID closed loop operation: If PID close loop operation is selected by P0.01 (set the
value to 9), the inverter will choose PID closed loop operation mode. In other word,
it will come into PID adjustment as the PID feed and PID feedback. (see parameter
group P7).
 Wobble frequency operation: If Wobble frequency operation mode is active (set
value of parameter code P0.01 to 10), the inverter will come into Wobble frequency
operation. The Wobble frequency running parameters can be modified in parameter
group P6. By selecting a multi-function terminal and setting the value to 46,
connecting the terminal to terminal “COM”, Wobble frequency operation state can
be reset ( Refer to chapter 4, see details P3 description)
 PLC programmed operation: If PLC programmed operation mode is selected by
P0.01 (set the value to 8), the inverter will chose PLC programmed operation:
every steps can be pre-defined (see parameter group P5 description). By selecting a
multi-function terminal and setting the value to 43, connecting the defined
multi-function terminal to “COM”, PLC programmed operation state can be
stopped. If the value of a multi-function terminal is 44, connect the defined
multi-function terminal to “COM”, PLC programmed operation state will be
reset(see parameter group P3 description).
 Common operation modes: in these modes, the inverter will run at open loop mode.
Common operation modes include 7 operation modes, they are keyboard, terminal
AI1, terminal AI2, pulse input, serial communication, multi-speed and terminal
UP/DOWN operation.
3.3.2 Checkpoints Before Operation
 To ensure safety, prior to initial operation, disconnect the machine coupling so that
the motor is isolated from the machine. If initial operation must be performed while
the motor is still coupled to the machine, use great care to avoid potentially
hazardous conditions. Check the following items before a trial run:
 Wiring and terminal connections are proper.
 Wire clippings and other debris removed from the unit.
 Screws are securely tightened.
 Motor is securely mounted.
 All items are correctly grounded.
 Keyboard Display at Power-Up.
3.3.3 Operation Checkpoints
 Motor rotates smoothly.
 Motor rotates in the correct direction.
 Motor has neither abnormal vibration nor noise.
 Acceleration and deceleration are smooth.
 Unit is not overloaded.
 Status indicator and keyboard display are correct.
