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.Chapter 5, tables of the functional parametersMonitor objects:No.Function descriptionRange and definition of the setting valueFactory set-valueSettable or

Basic functions:F01, operation control mode                               factory set value: 0Operation start/stop order0: operation keyboardThe buttons FOR (positive rotation), REV (reverse rotation), STOP are valid.1: terminal blockFOR, REV and COM of the terminal block are short-circuiting to control the positive and negative rotation. See Pr. E11.2: RS485 controlRS485 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: 10: the up and down buttons of the keyboard (the keyboard gives the frequency), Pr. F03.1: analog inputThe 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 speedReverse 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 operationThis 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 operationReverse rotation prevention can't limit it. The rotation direction is determined by the setting of multi-section speed operation direction.5: wobbulate operationNo reverse rotation function. No upper or lower frequency limit.6: PID adjusting operationNo reverse rotation function.7: RS485inputFulfill control according to the protocol via terminals SG+ and SG-.F03, keyboard setting frequency                        factory set value: 50.00This parameter is valid in keyboard governing mode and the parameter at this time is the setting frequency. Modify this parameter in large range is convenient now, but only the final setting value functions.F04, SPWM produce mode                                factory set value: 10: gradually sync modulation1: endless sync modulation2: asynchronous modulationThe user can select the best modulation mode according to the actual operation condition.F05, first-section accelerating time at1                    factory set value: 10.0The acceleration time is from 0Hz to the max frequency.F06, first-section deceleration time dt1                    factory set value: 10.0The deceleration time is from the max frequency to 0Hz.time  F07, inching accelerating time setting                      factory set value: 2.0F08, inching deceleration time setting                      factory set value: 2.0F09, inching frequency                                factory set value: 5.00Upper 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 timeInching 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:0Supply 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 modeConsumption 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: 0When 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: 0After 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: 0When 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:YesOnly large or medium power frequency controller has this function.F40, the min operation frequency                           factory set value: 0When 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: 0O:The actual rotation direction is the same as the given one.l:The actual rotation direction is the inverse of the given one.
