In the terminals 2 and 3 you can connect the inputs from an incremental encoder for the current
feedback in response to encoder. Signals can come from encoder powered from +5V to +24V).
Minimum high logic level >+2.8V/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.

Ausiliary power V (out)
(M2 signal terminal pin 1)
On the terminal (+V) is available auxiliary power supply v5V (+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.

DRIVE
D.T
The following diagram shows the connection from tachogenerator and the drive DC ONE.
This function is enabled through the following settings on the solder point, and the insertion of RDT
resistance on the adjstustement zone. +TACH "pin 9" corrisponds to power supply’s negative GND
input.
Connect the negative of tachometer to pin 10. Do not exceed voltage as input from tacho value of
50V. Example: If you use a 10V/KRPM no more than 5000rpm
If the motor rotates in an opposite direction to the expected one,switch off and reverse the motor
and tachogenerator connections.
