3.1.3. + Tacho (5)
3.1.4. – Tacho (6)
For operating mode tacho control an analog tacho has to be connected to these inputs.
Input impedance:
50 kOhm
Maximum input voltage:
50 V
Important: at cw turning of motorshaft the potential of the Tacho has to be higher than the
potential of - Tacho to close the control loop.

3.2.2. supervising report Error Out (11)
The error-signal is to show the status of the drive and can be used to provide a feedback signal to
other devices and controls. The open-collector is normally turned off which means the output is
pulled to a positive level by the means of an external resistor. In the case of a fault the output is
pulled to GND.
Input voltage range: max. 30 V DC
Load current:
< 20 mA
