No. Name/Value Description Def
12 CONSTANT SPEEDS
Constant speeds. Constant speed activation overrides the external speed
reference. Constant speed selections are ignored if drive is in the local
control mode.
As default constant speed selection is made through digital inputs DI3 and
DI4.1 = DI active, 0 = DI inactive.
DI3 DI4 Operation
0 0 No constant speed
1 0 Speed defined by parameter 1202 CONST SPEED 1
0 1 Speed defined by parameter 1203 CONST SPEED 2
1 1 Speed defined by parameter 1204 CONST SPEED 3
1202 CONST SPEED 1 Defines constant speed 1 (that is drive output frequency). E: 5.0 Hz /

13 ANALOG INPUTS Analog input signal minimum
1301 MINIMUM AI1 Defines the minimum % value that corresponds to minimum mA/(V) signal for
analog input AI1.
0...20 mA = 0...100%
4...20 mA = 20...100%
When analog input AI1 is selected as the source for external reference
REF1, the value corresponds to the minimum reference value, that is 0 Hz.
See the figure for parameter
1105 REF1 MAX.
0%
0
…100.0%
Value in percent of the full signal range. Example: If the minimum value for
analog input is 4 mA, the percent value for
0…20 mA range is:
(4 mA / 20 mA) · 100% = 20%
20 LIMITS Maximum frequency
2008 MAXIMUM FREQ Defines the maximum limit for the drive output frequen cy.

21 START/STOP Stop mode of the motor
2102 STOP FUNCTION Selects the motor stop function. 1 = COAST
1 = COAST Stop by cutting off the motor power supply. The motor coasts to stop.
2 = RAMP Stop along a linear ramp. See parameter group 22 ACCEL/DECEL .
