Dc
In the terminals 10 and 11 can connect the inputs from an incremental encoder for the current
feedback in response to encoder. signals can come from encoder powered from +5 V to +24 V).
Minimum high logic level> +2.8 V/24Vmax,
Minimum low logic level <1.5V
Encoder can be connected either push-pull (wires A, B and GND) or line-driver encoder type (wires
+ A + B and GND). Remember to connect the zero encoder with the GND power converter.
View the connections and settings from encoder in chapter 4.1
2.7
Encoder inputs
(or tacho input)
When the motor have a tachogenerator you can use the terminal 10 as input for this feedback.
Connect this terminal to the negative of tachometer. Do not exceed voltage as input from tacho
value of 50V.
Example: If you use a 10V/KRPM no more than 5000rpm.

Tachogenerator input
(Signal terminal pin 10)
2.8
Ausiliary power 5V
(Signal terminal pin 12)
On the terminal 12 (+ V) is available auxiliary power supply v5 V (+12 V on request order).
This output can be used to power the encoder on the motor. The capacity of the output current is
130mA max.
2.9
Signal common ground
(Signal terminal pin 4-13)
Signal Common Ground. Corrisponds to power supply’s negative GND input.
(Signal terminal pin 10-11)
