Mode 8: Setting the step size / hysteresis
Use this to select the hysteresis.
In control mode , the hysteresis setting determines the level at which a change to the
analogue input signal will cause the drive to readjust the position. This setting therefore
has a direct effect on the resolution of the available steps in control mode. A stable and
low-interference analogue input signal is required in order to set a fine-tuned
hysteresis. The stability of the measurement of the analogue input signal can therefore
also be influenced by the averaging (Mode 6: Setting the averaging) setting. With a
very finely tuned hysteresis, the duration of the ramp (mode 7) must not be too short.
In three-point step mode , the hysteresis setting determines the level of precision with
which the end positions are approached. The higher the hysteresis setting, the earlier
the motor is switched off when an end position is reached.
In three-point step mode and control mode , this setting also determines the
hysteresis of the end position relays.
Parameters 0-9: Select the hysteresis in 10 steps from 0.05% to 2.0%. The values
refer to an opening angle of 90°.
Mode 9: Setting the end positions
(Images for drive 00-15 as reference)
The position is determined by the electronic control of the drive using a potentiometer
mounted on the CPU board. The potentiometer is connected to the output shaft without
play. The positions of the two end positions are also determined by the electronics via
the potentiometer.
The scalings used for the external setpoint input and the position feedback
automatically adapt to the newly set positions for the end positions.
