Note Frequency reference 1 is enabled in remote mode with n03 for frequency reference selection set to 1. Note These frequency references are selected with multi-step speed references (multi-function input). 0. 0 to max. 6. 0 frequency 0. 0 Yes 0. 0 Yes 0. 0 Yes 0. 0 Yes 0. 0 Yes 0. 0 Yes 0. 0 Yes Used to set the inching frequency command. Note The inching frequency command is selected with the inching command (multi-function input). The inching frequency command takes precedence over the multi-step speed reference. 6. 0 Yes 3-6 List of Parameters Parameter Name No. (Hex)) n30 Frequency (011E) reference upper limit n31 Frequency (011F) reference lower limit n32 Rated motor (0120) current Description Setting range Default setting Chapter 3 Changes during operation No Memo Used to set the upper and lower fre- 0 to 110 quency reference limits in percentage based on the maximum frequency as 100%. Note If n31 is set to a value less than the minimum output frequency (n14), the Inverter will 0 to 110 have no output when a frequency reference less than the minimum output frequency input is input. Used to set the rated motor current for motor overload detection (OL1) based on the rated motor current. Note Motor overload detection (OL1) is disabled by setting the parameter to 0. 0. Note The rated motor current is default to the standard rated current of the maximum applicable motor. Used to set the motor overload detection (OL1) for the electronic thermal characteristics of the motor. 0: Protection characteristics for general-purpose induction motors 1: Protection characteristics for inverter-dedicated motors 2: No protection Note If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. 0. 0 to 120% of rated output current of the Inverter. 100 0 No Varies with the capacity. No n33 (0121) Motor protection characteristics 0 to 2 0 No 3-7 List of Parameters Parameter Name No. (Hex)) n34 Motor protec(0122) tive time setting Description Setting range Default setting Chapter 3 Changes during operation No Memo n35 (0123) Cooling fan operation function Used to set the electric thermal char- 1 to 60 acteristics of the motor to be connected in 1-minute increments. Note The default setting does not require any changes in normal operation. Note To set the parameter according to the characteristics of the motor, check with the motor manufacturer the thermal time constant and set the parameter with some margin. In other words, set the value slightly shorter than the thermal time constant. Note To detect motor overloading quicker, reduce the set value, provided that it does not cause any application problems. Used to operate the Cooling Fan of 0, 1 the Inverter while the Inverter is turned on or only while the Inverter is in operation. 0: Rotates only while RUN command is input and for 1 minute after Inverter stops operating 1: Rotates while Inverter is turned on Note This parameter is available only if the Inverter incorporates a Cooling Fan. Note If the operation frequency of the Inverter is low, the life of the fan can be prolonged by setting the parameter to 0. 8 0 No 3-8 List of Parameters Parameter No. [. . . ] Buyer shall have no right to set off any amounts against the amount owing in respect of this invoice.
