(1) Programmable operation disabled ([b00]3)· This parameter is used to set the delay time between the deceleration, stop and the start of reversed acceleration when the motor rotating speed changes. The parameter should be set according to load inertia, and Acc./Dec. time.(2) Programmable operation enabled ([b00] =3)TimeOutput frequency· When the forward and reverse signals are input simultaneously, the motor will decelerate and stop. When “0.0s” is set, the reverse operation is forbidden and only the forward operation is allowed.Output frequencyReversedForward· Electronic thermal relay setting value (%)=(motor rated current /frequency converter rated current) ×100%. When single motor is connected to single converter, overload relay needs not to be connected externally, and set the parameter according to motor characteristic.· When driving several motors or motor rated current is lower than the set value Et, the motor is not protected actively. In that case, please equip each motor with thermal protection relay.· As the figure of overload protection reverse time-limit shows, for general series: 150% rated current for 1 minute, 110% rated current for 1 hour.· If it is not set as OFF, the range is “50~110%”.frequency and over excitation of the motor can also be avoided while it is running without load.In the real operation, the voltage increase percentage is decided by the frequency converter based on the present output frequency and the load current.[b19] should be increased step by step. Too big value of the parameter may cause over current ofthe motor or enable the Auto Current Limit function. If it is not set as “oFF”, the setting range is “1~10%”. · When “oFF” is set effective, the automatic torque increase function is disabled; when other values are set, the values are the percentag e of the increased voltag e at 0 output frequency, rated current. This parameter is to improve the torque characteristic when the motor is running at low frequency. With that function, the output voltag e of the frequency converter can be adjusted· UF is the Max. frequency which the frequency converter outputs during steady running.· LF is the Min. frequency which the frequency converters outputs during steady running.· When the input frequency command is lower than the set value of the lower limit frequency (LF), the frequency converter has two working modes:[b23]=0, the output frequency is decreased directly from the lower limit frequency to 0.00Hz; the hysteresis frequency width needs to be set in order to prevent frequency converter from the frequency RUN/STOP around the lower limit frequency.[b23]=1, the frequency converter is kept running at the lower limit frequency.General series[b26] defines the time constant of the first inertia to conduct the first inertia filter of the analoginput reference sig nal. The big g er the time constant, the more obvious the restraining effect, but the slower the response. [b26] is also the filter time constant of FB channel.Reference frequency signal is filtered and amplified, and then its relationship with the set frequency is determined by the Curve (defined by [b27]~[b30]), which is shown in the right hand figure.compensation, and decrease the slip so that the motor can run at the rated current and the speed is close to the synchronous speed. Consumer will set slip frequency compensation according to load. Customers can use the slip frequency compensation according to the load situation.Note: when using the slip frequency compensation, [H35]must be disabled, [H35]=0.00.Note: If the compensation is set too big, the motorspeed will exceed the synchronous speed. In this case: Upper limit frequency=output frequency + K ×slipfrequency [b31].K is associated with load current and is not bigger than 1.· The relationship between frequency source and frequency setting is shown in the next figure, when VRC,+I pulse or panel potentiometer are set as open-loop frequency setting channels.· Using analog signal (0~5V, 0~10V, 4~20mA, panel potentiometer 0~5V) and pulse frequency to set frequency, outputfrequency can be set freely by setting [b25] and [b27], [b 28],[b29], [b30].The motor has two stop modes: Deceleration stop and inertia slide stop.[b34]=0: Inertia stop disabled, deceleration stop active.[b34]=1~3: external terminals X1,X2 or X3-COM are closed to realize inertia slip stop with. When other stop orders are set, deceleration stop is active.[b34]=4: inertia slide stop.If the setting is 1~3, when the selected terminal and the COM terminal are closed during operation,the converter will be stopped in inertia stop mode immediately and F.r .on will be displayed at the same time as the external terminals are closed. Once the terminals and COM are open, the output accelerates again from 0.00H to the set frequency. If there is stop signal, but the selected terminal and the COM open, then the motor decelerates to stop. If X1, X2 or X3 have alreadybeen defined with other functions, then the [b34] does not show the corresponding parameter in order to avoid repeated definition ofterminals.[b32] This function could regulate starting torque characteristic with torque compensation, but if the setvalue is too big, over current may happen.[b33] Start up hold time is the running holding time with the start up frequency.If the running frequency is lower than start up frequency, the output frequency is the start up frequency.After the holding time of the start up frequency, the output frequency will be decreased to the running· [b35]=0: Cannot carry on the Jog operation.· [b35]=1~3: Selection terminals X1~X3 as the jog operation signal input terminals, close is enabled. When the jog operation signal and the operation signal are enabled at the same time, then the jog operation is effective.Jog operation is forbidden in the programmable mode.Jog operation acceleration time[b37] is time for frequency increase from 0.00Hz to HF. Jog operation deceleration time [b38] is time for frequency decrease from HF to 0.00Hz.When the Jog operation stops, if the jog operation frequency is higher than the set operation frequency, then decrease the frequency to the set frequency according to the Jog deceleration time.If the Jog frequency is lower than the operation frequency, then increase the frequency to the set frequency according to the normal acceleration time.
