Operation frequency can be limited by setting maximum frequency, start frequency, upper limit frequency and lower limit frequency.

Frequency Limit Using Maximum Frequency and Start Frequency - Setting Details

Code Description

dr.19 Start Freq

Set the lower limit value for speed unit parameters that are expressed in Hz or rpm. If an input frequency is lower than the start frequency, the parameter value will be 0.00.

dr.20 Max Freq

Set upper and lower frequency limits. All frequency selections are restricted to frequencies from within the upper and lower limits.

This restriction also applies when you in input a frequency reference using the keypad.

Frequency Limit Using Upper and Lower Limit Frequencies - Setting Details

Code Description

Ad.24 Freq Limit

The initial setting is 0(No). Changing the setting to 1(Yes) allows the setting of frequencies between the lower limit frequency (Ad.25) and the upper limit frequency (Ad.26). When the setting is 0(No), codes Ad.25 and Ad.26 are not visible.

Ad.25 Freq Limit Lo, Ad.26 Freq Limit Hi

Set an upper limit frequency to all speed unit parameters that are expressed in Hz or rpm, except for the base frequency (dr.18). Frequency cannot be set higher than the upper limit frequency.

4.18.3Frequency Jump

Use frequency jump to avoid mechanical resonance frequencies. Jump through frequency bands when a motor accelerates and decelerates. Operation frequencies cannot be set within the pre-set frequency jump band.

When a frequency setting is increased, while the frequency parameter setting value (voltage, current, RS-485 communication, keypad setting, etc.) is within a jump frequency band , the frequency will be maintained at the lower limit value of the frequency band. Then, the frequency will increase when the frequency parameter setting exceeds the range of frequencies used by the frequency jump band.

_{Operation Mode Setting}

Apply two types of operation modes and switch between them as required. For both the first and second command source, set the frequency after shifting operation commands to the multi- function input terminal. Mode swiching can be used to stop remote control during an operation using the communication option and to switch operation mode to operate via the local panel, or to operate the inverter from another remote control location.

Select one of the multi-function terminals from codes In. 65–71 and set the parameter value to 15 (2nd Source).

2nd Operation Mode Setting Details

Code Description

bA.04 Cmd 2nd Src bA.05 Freq 2nd Src

If signals are provided to the multi-function terminal set as the 2nd _command source (2nd Source), the operation can be performed using the set values from bA.04-05 instead of the set values from the drv and Frq codes in the Operation group.

The 2nd command source settings cannot be changed while operating with the 1st _{command source (Main Source).}

• When setting the multi-function terminal to the 2nd _{command source (2nd Source) and input (On)} the signal, operation state is changed because the frequency setting and the Operation command will be changed to the 2nd _{command. Before shifting input to the multi-function terminal, ensure} that the 2nd _{command is correctly set. Note that if the deceleration time is too short or inertia of the} load is too high, an overvoltage fault trip may occur.

• Depending on the parameter settings, the inverter may stop operating when you switch the command modes.
