7. Description of Inputs and Outputs
7.1 Digital
Inputs
Enable In: Activating or Disabling the Output Stage
If the
Enable In
input is at GND potential or not wired at all, the output stage remains in the
locked state. The motor stands still or slow down without brake. To reactivate the output
stage, a voltage signal >8 V to the
Enable In
input XA/14 is necessary.
Additional information about the schematic refer chapter 3.2.
Range of Input Voltage
0 to +30 VDC
Input Impedance
30 kOhm to GND
Enable
activated
>8 VDC
Enable
disabled
open or connected to GND
Note:
The voltage output
V
can be used as source for the
Enable In
input.
Encoder A, /A, B, B, I, /I: Encoder Feedback of the Motor
The encoder inputs XB/15 to XB/20 are connected to the incremental encoder outputs of the
motor. The supply voltage is given by the
+5V
output at XB/22 to GND. The drive needs the
signals to control the speed.
Additional information about the schematic refer chapter 3.2.
Range of Input Voltage
0 to +24 VDC
Input Impedance
5 kOhm
Input Frequency
max. 600 kHz
Permanent Input Protection
-5 to +30 VDC
High level at +5 V
>3 VDC
Low level at +5 V
<1,7 VDC
High level at +24 V
>13 VDC
Low level at +24 V
<5,5 VDC
