Disable Rev: Activating or Disabling one Direction of Rotation
If the Disable Fwd input is at GND potential or not wired at all, the motor works only in one
direction e.g. counter clockwise. To activate this direction, a voltage signal >8 V to the
Enable input XB/13 is necessary.
Additional information about the schematic refer chapter 3.2.
Range of Input Voltage 0 to +30 VDC
Input Impedance 4.5 kOhm to GND
Direction activated >8 VDC
Direction disabled open or connected to GND
Encoder A / B: Encoder Feedback of the Motor
The encoder inputs XB/7 and XB/8 are connected to the encoder output of the motor. The
supply voltage is given by the +5V output at XB/6 to GND. The drive needs the signals
control the speed.
Additional information about the schematic refer chapter 3.2.
Range of Input Voltage 0 to +5 VDC
Input Impedance 1 kOhm to +5V
Input Frequency max. 100 kHz
Permanent Input Protection -5 to +10 VDC
High level >2,4 VDC
Low level <1 VDC
WARNING:
Correct connection of the encoder is crucial. Otherwise the motor operates at
maximum speed without any control.
