Actual signals and parameters
Description
Analog input signal minimum
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, i.e. 0 Hz. See
the figure for parameter 1105
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%
Maximum frequency
Defines the maximum limit for the drive output frequency.

Maximum frequency
Stop mode of the motor
Selects the motor stop function.
Stop by cutting off the motor power supply. The motor coasts to a stop.
Stop along a linear ramp. See parameter group
Acceleration and deceleration times
Defines the acceleration time 1 i.e. the time required for the speed to change
from zero to the speed defined by parameter
- If the speed reference increases faster than the set acceleration rate, the
motor speed will follow the acceleration rate.
- If the speed reference increases slower than the set acceleration rate, the
motor speed will follow the reference signal.
- If the acceleration time is set too short, the drive will automatically prolong
the acceleration in order not to exceed the drive operating limits.
