TB205 Rev1 Direction Reversal on Paired Axis
Overview
Parameter 64 enables the 4th and 5th axes to be paired together or individually be run in a slaved state with
any of the other axes This is intended to drive 2 screws on opposite sides of a table probably a router table
or gantry system In the motor configuration screen the direction reversal has to match the paired axis For
example if the 4th axis is paired with the Y axis and the Y axis has direction reversal turned off then the 4th
axis needs direction reversal turned off as well If you need the 4th axis to move in the opposite direction of it's
paired counter part you must follow theses steps to modify the 4th axis motor wiring
DC Systems
Procedure
1 Swap the motor power leads The Black wire will go to the "Motor +" terminal on the DC single and the Red
wire will go to the "Motor " terminal on the DC single
2 Swap the A and B encoder channels The Black\White wire from "A\" will go to Pin 5 on the DB9 connector
The Black\Blue wire from "B\" will go to Pin 4 on the DB9 connector The White wire from "A" will go to Pin 8
on the DB9 connector The Blue wire from "B" will go to Pin 7 on the DB9 connector

AC Systems
Procedure
When slaving an AC motor equipped with a Dynapar encoder the following chart should be used  The motor
connections on the SD drive must have Phase U
and Phase W
swapped The Direction Reversal must be set
to Yes

Before running the motor it may have to be re aligned Please follow the following procedure when aligning an
encoder or read TB166
1 Remove motor from machine if not already removed
2 Remove back end cap on the motor
3 Connect power cable and encoder cable from drive to the motor with drive off
4 Connect encoder leads to the end cap connector If encoder is mounted to the motor remove encoder
5 Power control and pull out E stop
6 Go to the PID then to the DRIVE MENU Then MOVE SYNC several times by pressing F2 ?MOVE SYNC?
and then F10 ?GO? You should see the shaft rotate The first rotation may have a jerk to it but after that the
shaft should rotate smoothly
7 Rotate the encoder shaft until the encoder reading is Zero Mount the encoder on the rear motor shaft in
this position Snug up the mounting ears screws and fine adjust to within +/ 10 counts of zero When the
encoder count rolls over it reads the max per rotation ex 8192 In this zone a red message should appear on
the control ?Tighten Encoder Now?
8 Tighten encoder mounting screws
9 Hit MOVE SYNC as many times as needed to return to the zero position and verify the zero reading
Observe the commutation count goes 1 through six consecutively Adjust and retry if necessary At a rest
position the commutation zone should be either a 1 or a 6 only If not reboot the machine and start again
10 Replace end cap and apply ?index set? sticker on motor This motor is ready for operation AFTER THE
SYSTEM HAS BEEN REBOOTED
11 Install motor on machine
