2.2 SPEED
CONTROL
2.2.1
Nominal Linear Speed
Nominal linear speed corresponds to the lift speed at nominal frequency of the motor
(
Speed parameters in group 2.2.3 are entered in linear magnitudes.
2.2.2
Speed reference selection
Defines which frequency reference source is selected when controlled from the I/O
control place. Default value is 0.
0 = Activity coding
1 = Activity coding with direction
2 = Binary coding
4 = Fieldbus
5 = Keypad
Speed reference can be determined in three different ways with the external digital
inputs on option board.
The first column contains the state of the digital inputs (marked as DIE1, DIE2 and
DIE2).
The second column contains the parameter and the next column the corresponding
speed reference. The priority column defines which speed is activated if more than one
digital input is activated. If Speed reference is different when running to different
direction the direction is defined in direction column.
0 = Activity coding
Four different constant speeds can be selected.
