(10) Setting prohibit frequencies 1 to 3 (Cn-16 to Cn-18)Set a setting prohibit frequency in units of 0.1 Hz. A set value of 0.0 Hz disables thisfunction.If the setting prohibit frequency ranges overlap, set setting prohibit frequency 1 to 3as shown below:Cn-18 Cn-17 Cn-16(11) Setting prohibit frequency range (Cn-19)Set the range of setting prohibit frequency in units of 0.1 Hz. The range of the settingprohibit frequency is determined as follows, depending on combinations with Cn-16to Cn-18.Cn-16 to Cn-18 Cn-19 the range of the setting prohibit frequency Cn-16to Cn-18 Cn-19Cn-19SETTING PROHIBITFREQUENCY RANGEINTERNALFREQUENCYREF.Cn-17SETTING PROHIBITFREQUENCYCn-16SETTING PROHIBITFREQUENCYSETTING FREQUENCY REF.Note: Constant-speed operation is prohibited in the setting prohibit frequency range. Outputfrequency does not jump during acceleration or deceleration, which is performed smoothly.(12) Digital Operator Display Unit (Cn-20)The setting unit of frequency references 1 to 8 and jog frequency reference dependson the set value of operator display mode (Cn-20) as follows:Cn-200 Units of 0.01 Hz1 Units of 0.01%2 to 3940 to 39999Cn-18SETTING PROHIBITFREQUENCYSetting / Reading UnitSet in the units of r / min (0 to 39999).r / min = 120 x frequency reference (Hz) / Cn-20(Set the number of motor poles in Cn-20)The position of decimal point is set by the value of the 5th digit of Cn-20.Value of 5th digit = 0: Displayed as XXXXValue of 5th digit = 1: Displayed as XXX.XValue of 5th digit = 2: Displayed as XX.XXValue of 5th digit = 3: displayed as X.XXXA set value of 100% frequency is dewii6ned by the 1st digit to 4th digit of Cn-20.Example 1: When the set value of 100% speed is 200.0, Cn-20 = 12000 is set.100% speed is displayed as 200.0 at Cn-29 = 12000.60% speed is displayed as 120.0Example 2: When the set value of 100% speed is 65.00, Cn-20 = 26500 is set.60% speed is displayed as 39.00 at Cn-20 = 26500.54
