Setting the direction of rotation:
Command Function
Description
ADL
Analog Direction Left
Positive voltages at the analog input result in anti-
clockwise rotation of the rotor
ADR
Analog Direction Right
Positive voltages at the analog input result in clock-
wise rotation of the rotor
Example:
Clockwise rotation in the case of positive voltage:
ADR
The error output (fault pin) can also be reconfigured as a digital rotational direction input:
Command Function
Description
DIRIN
Direction Input
Use fault pin as rotational direction input
Control and direction:
Low:
... Left-hand rotation (corresponding to ADL command)
High:
... Right-hand rotation (corresponding to ADR command)
The level at the rotational direction input overrides the settings made with ADR and ADL. ADR and
ADL are thus ineffective.
Set-point presetting via pulse width signal (PWM) at the analog input (SOR2):
At delivery:
pulse duty factor > 50 %
Clockwise rotation
pulse duty factor = 50 %
Stoppage
pulse duty factor < 50 %
Anticlockwise rotation
The commands SP, MV, MAV, ADL and ADR can also be used here.
Make sure that APL0 is set, if you do not want the drive to stop at the set range limits.
Input circuit
The input circuit at the analog input is designed as a differential amplifier. If the analog input is
open, an undefined velocity can be set. The input must be connected to AGND with low-impedance
and set to the voltage level of the AGND, in order to generate 0 rpm.
