Installation procedures

851-160572 / B

Signal phase 1: S1-L (20-70V) pin 2

S1-M (80-140V) pin 9

S1-H (150-220V) pin 1

Signal phase 2: S2-L (20-70V) pin 11

S2-M (80-140V) pin 3

S2-H (150-220V) pin 10

Signal phase 3: S3-L (20-70V) pin 5

S3-M (80-140V) pin 12

S3-H (150-220V) pin 4

Reference: +/- REF pin 7

-/+ REF (see note) pin 15

Note If the output voltage is only half-wave rectified, the other

reference from the gyro which is not used for the three phases

must be connected to pin 15.

2 Locate the 15 pin D-connector, the connector housing and

the shrink tube in the spare parts box. Refer to the output

voltage which was written into the table for the stepper

data specifications, and make the connections to the

15-pin D-connector with reference to the pin-connection

list above. Also refer to figure 21 which shows the pin

location of the connector seen from the wire soldering

side. The cable screen should be connected to the

connector housing.

gyro with stepper output

In order to read the data from the gyro, some DIL switches on

the printed circuit board in the electronic drawer unit behind the

operator panel must be selected. Use the following procedure to

set the switches.
