3.35 FEEDBACK FROM ENP/NR

For the enP/Nr connection, the following may be used:
1. The M1 screw double terminal board with 44 terminals.
2. The CN2 9-pole D-connector.
In both cases, all the available input channels and supply values are optoinsulated with respect to the
analog inputs potential. When choosing the enP/Nr type, check the max. speed frequency, that may be
obtained from the following formula
pulses for each complete rotation and n
Using the screw terminal board.
In the first event the features of the enP/Nr to be connected are the following:
1a. Complementary push-pull enP/Nr or NPN-type or Open Collector
2a. High level of the output waveform on the three channels equal to 24 VDC max
3a. Input maximum frequency equal to 102.400k Hz (e.g. 1024 pulse/rev for 6000 RPM max.)
4a. 5 Vdc or 24 Vdc voltage available for enP/Nr supply through DCREG drive
The following terminals should be used:
14 - Input for channel A
16 - Input for channel B
12 - Input for channel N (
The enP/Nr screened cable shield should be connected to the ground potential as directly as possible.
Use one of the 3 collar-shaped cable fasteners located on the bottom of the control board supporting
guard.
Using the D-connector.
In the second case the features of the enP/Nr to be connected are the following:
1a. Line-driver enP/Nr (RS422 output standard)
2a. High level of the output waveform on the six channels ranging from 5...15 Vdc
3a. Max. input frequency equal to 102.400k Hz (e.g. 1024 pulse/rev for 6000 RPM max)
4a. 5 Vdc or 24 Vdc enP/Nr supply through DCREG drive
The following D-connector pins should be used:
pin 1 - Input for channel A
pin 2 - Input for channel A
pin 3 - Input for channel B
pin 4 - Input for channel B
pin 5 - Input for channel N (
In this case, it is not necessary to use one of the three collar-shaped cable fasteners located on the
bottom of the control board supporting guard to connect the screened cable shield of the enP/Nr to the
ground potential, unless a screened 9-pole flying male connector is used. Said connector is to be
assembled inside a screening metal body:
ITT-CANNON mod. DE121073-154 (connector body) + n.2 250-8501-013 (pair of long fastening screws).
FRAMATONE mod. 8655 MH 09 01.
In that way, the ground potential on 90° female connector in the control board will be transmitted to the
metal body, then to the screened cable shield connecting the enP/Nr.
The connector body is supplied by ELETTRONICA SANTERNO (P/N CN0420000), as well as 9-pole D-
connector (P/N CN0400018).
( 1 ) This is not required for the speed feedback, but is required for the position control.
