8 PARAMETER DESCRIPTIONS
On the following pages you find the parameter descriptions arranged according to the
individual ID number of the parameter. An asterisk after the parameter ID number (e.g. 418
Motor potentiometer UP *) indicates that the TTF programming method must be applied to
this 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 is
available in all applications. See below. The parameter numbers under which the parameter
appears in different applications are also given.
1.
Basic Application
2.
Standard Application

Local/Remote Control Application
4.
Multi-Step Speed Control Application
5.

101 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 320
Hz.
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 to
maximum frequency.
104 DECELERATION TIME 1 (2.4, 2.1.4)
Gives the time that is necessary for the output frequency to decrease from maximum
frequency 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 the
appropriate digital inputs are activated
Parameter values are automatically limited to the maximum frequency (ID102).
