5. Pay attention to the followings when wiring:
? Do not add phase-in capacity or resistance-capacity absorbing device at U, V and W output terminals of the frequency controller.
? Power off the frequency controller when change the motor.
? Do not switch the motor or the power-frequency supply until the frequency controller stops outputting.
? To avoid electromagnetic interference, when the distance between the frequency controller and the electromagnetic contactor or the relay is near, surge absorbing device can be added.
? Must add insulating device on external control line or adopt shielded line.
? Besides shielded line, the input order signal line shall be single wired and it is better to wire it far from the main loop.
? When the carrier frequency is below 3 KHz, the max distance between the frequency and the motor shall be smaller than 50m; this distance shall be shorted accordingly if the carrier frequency is above 4 KHz. The wiring is better to be inside the metal tube.
? When add peripheral units (wave filter, reactor, etc.), measure the insulating resistance to the ground by 1000V megohm meter at first to ensure that the resistance is not lower than 4MΩ.
? Do not power off if the frequency controller needs frequent starting. Start or stop it by COM/FOR of the control terminal, the keyboard or the RS485 operation order to avoid the damage of the commutate bridge.
? Do not connect the AV power supply to the frequency controller output terminals U, V and W.
? The grounding terminals (E or ) must ground reliably (the grounding resistance shall be under 100Ω) to avoid any electrical leakage.
? When wire the main loop, the width of the wire shall be subject to the relative specifications of the national electric specification.
The capacity of the motor shall be equal to or smaller than the capacity of the frequency controller.

Basic functions:
F01, operation control mode factory set value: 0
Operation start/stop order
0: operation keyboard
The buttons FOR (positive rotation), REV (reverse rotation), STOP are valid.
1: terminal block
FOR, REV and COM of the terminal block are short-circuiting to control the positive and negative rotation. See Pr. E11.
2: RS485 control
RS485 communication operation order controls the operation. When the fault resets, the STOP button of the keyboard, RST terminal and the "STOP" order in RS485 communication are all valid orders.
F02, frequency setting mode factory set value: 1
0: the up and down buttons of the keyboard (the keyboard gives the frequency), Pr. F03.
1: analog input
The analog input channel is determined by analog input option Pr. E14. Signal input enters from V2 and I2 of the terminal block.
2: terminal block multi-section speed
Reverse rotation prevention can't limit it. The rotation direction is determined by the setting of multi-section speed operation direction.
3: Up/down controls the operation
This function is as that of the multi-section speed, which operates in terminals (SS1, SS2) operation state. When this function is valid, multi-section speed operation is invalid. Hereinto, SS1 is lift control and SS2 is fall control.
The time of the up and down is as the setting of first-section speedup and slowdown. The output frequency is limited by the upper and lower limiting frequency. This function has no reverse rotation function.
: Program operation
Reverse rotation prevention can't limit it. The rotation direction is determined by the setting of multi-section speed operation direction.
5: wobbulate operation
No reverse rotation function. No upper or lower frequency limit.
6: PID adjusting operation
No reverse rotation function.
7: RS485input
Fulfill control according to the protocol via terminals SG+ and SG-.
F03, keyboard setting frequency factory set value: 50.00

Upper and lower limiting frequency can't limit the inching frequency.
The definition of inching accelerating/deceleration time is the same as that of the first-section.
The max frequency
Inching frequency
0 time
Inching accelerating time inching deceleration time
Inching order of the terminal has the priority. That is, in whatever governing mode, once the inching order is valid, immediately accelerate/slow down to the inching frequency from the current operation frequency at the accelerating/deceleration time in current governing mode.
Keyboard inching order hasn't got the priority.
Inching was set as fire control water supply function. Ex-factory set value of inching frequency is 50.00Hz and the accelerating or deceleration time is 10.0Sec. When the fire control water supply is valid, the frequency controller immediately rises to 50.0Hz and the motor will operate at full speed to meet the requirement of fire control water supply.
The frequency and time of the turning point in reverse L curve of the speedup and down modes is determined by the inching frequency and 0.2 second.
See Pr.F11, Pr.F12 for details.
F10, special cabinet rise factory set value:0
Supply 33 V/F curves for selecting. Hereinto, 0 to16 are for constant torque load while 17 to 32 are for square decline torque load.
F11, accelerating mode factory set value:0 This frequency controller supplies four accelerating modes (0: direct line; 1: reverse L; 2: S; 3: fan type) to meet the usage requirement for different mechanism.
1:Safety mode
Consumption brake can't operate until the DC bus bar high voltage exceeds the setting value in decelerating process of the frequency controller.
2:general mode:
Consumption brake operates as long as the DC bus bar high voltage exceeds the setting value in any state of the frequency controller.
Over voltage or over current may happen when the frequency controller is operation in sudden deceleration state or fluctuation of load is sharp. It is easy to happen when the load inertia is larger. When the frequency inner part inspects that DC bus bar high voltage exceeds the certain value, the output brake signal takes consumption brake operation via the external connecting resistance. The user can utilize this function by selecting the machine with brake function.
F36, reset times after fault factory set value: 0
When over current, over voltage or over load occurs in frequency controller operation process, automatically reset and then operate in the setting mode before the fault. The reset times shall be subject to the parameter set, which is 10 times the most. When set 0, reset function can't be done after the fault, but DC main loop main relay fault MCC and low voltage fault are the exceptions. After reset, the frequency controller operates normally and after 30 seconds, the fault reset times will automatically return to the setting times.
F37, track start selection factory set value: 0
After selecting powering on/operation again after power-failure/fault manual reset/ fault automatic reset/start again after stop, if the parameter is set to be 1, rotational speed tracks start; if the parameter is set to be 0, start from 0.1HZ or from the start frequency (more than 0.1Hz).
F38, operation again after power-failure factory set value: 0
When the control part of the frequency controller powers off, and if the operation controlling parameter is 0 after repowering on, only keyboard is effective.
0:Don't operate after repowering on.
l:Keep the former operation state if the motor is running when repower on.
If repower on when the inner storage elements are still displayed on the nixie tube, the frequency controller will keep the former operation state whatever the parameter is.
F39, output open-phase protection selection factory set value: 0
0:No 1:Yes
Only large or medium power frequency controller has this function.
F40, the min operation frequency factory set value: 0
When the setting frequency is lower than the min operation frequency, the frequency controller will stop operation. That is, the setting frequency is considered to be 0.0Hz.
F4l, rotation direction inversion factory set value: 0
O:The actual rotation direction is the same as the given one.
l:The actual rotation direction is the inverse of the given one.

When terminals RST and COM are closed, the external fault signal is valid; when they close first and then open, reset signal is valid.
E06, percentage of low load warning factory set value: 0
Match low load warning when use this parameter.
Percentage of low load warning = the setting load operation current Ib/rated current Ia of the frequency controller
Cancel this function when set to be 0. When the frequency controller is operation at steady speed and one of the output terminals has been set to be 6: low load warning.

C05, Rated current of the motor
The rated current of the motor is allowed to set but it shall not exceed the rated current of the frequency controller. Factory set value is the rated current of the frequency controller.
Thsi parameter is to guarantee the over load protection capacity for the motor (that is OL curve) and the energy saving operation.
This parameter can avoid the over heat of the self-cooling motor in the operation at low speed and can protect the motor if the characteristic varies little but the motor capacity varies.
Set the rated current of the motor to be Ie.
