8 PARAMETER DESCRIPTIONSOn the following pages you find the parameter descriptions arranged according to theindividual ID number of the parameter. An asterisk after the parameter ID number (e.g. 418Motor potentiometer UP *) indicates that the TTF programming method must be applied tothis parameter (see Chapter 8.9 "Terminal to function" (TTF) programming principle).Some parameter names are followed by a number code indicating the "All in One"applications in which the parameter is included. If no code is shown the parameter isavailable in all applications. See below. The parameter numbers under which the parameterappears in different applications are also given.1. Basic Application2. Standard Application3. Local/Remote Control Application4. Multi-Step Speed Control Application5. PID Control Application6. Multi-Purpose Control Application7. Pump and Fan Control Application101 MINIMUM FREQUENCY (2.1, 2.1.1)102 MAXIMUM FREQUENCY (2.2, 2.1.2)Defines the frequency limits of the AC drive. The maximum value for these parameters is 320Hz.Minimum and maximum frequencies set limits to other frequency related parameters (e.g.Preset Speed 1 (ID105), Preset Speed 2 (ID106) and 4 mA fault preset speed (ID728).103 ACCELERATION TIME 1 (2.3, 2.1.3)Gives the time that is necessary for the output frequency to increase from zero frequency tomaximum frequency.104 DECELERATION TIME 1 (2.4, 2.1.4)Gives the time that is necessary for the output frequency to decrease from maximumfrequency to zero frequency.105 PRESET SPEED 1 1246 (2.18, 2.1.14, 2.1.15)106 PRESET SPEED 2 1246 (2.19, 2.1.15, 2.1.16)These parameters can be used to determine frequency references that are applied when theappropriate digital inputs are activatedParameter values are automatically limited to the maximum frequency (ID102).VACON · 234 PARAMETER DESCRIPTIONS8 TEL. +358 (0)201 2121 · FAX +358 (0)201 212 205
