Replacing a SD8055 (continued)
Indexer Connector Wiring Changes
h ± Step and ± Direction: Can be brought over directly to the SD17063.
h ± Enable Input: Can be brought over to the SD17063’s ± Disable Input. Any current limiting resistors
used because the input voltage exceeds 5 Vdc must be replaced. 12 to 15 Vdc systems
that used a 1KΩ resistor with the SD8055 must replace them with 2 KΩ resistors.
24 Vdc systems need to replace the 2 KΩ resistor with a 3.9 KΩ resistor.
h ± Fault Output:
Can be brought over directly to the SD17063, but you will probably want to reverse its
logic.
The logic of the fault outputs is reversed between the SD8055 and the SD17063. The Fault
Output of the SD8055 is normally off, and turns on when there is a fault, while the Fault Out-
put of the SD17063 is normally on and turns off when a fault occurs.
The simplest solution depends on your application. If you are using the fault output as an open
collector sinking output with a pull up resistor, it may be relatively simple to change the wiring
to an open collector sourcing output with a pull down resistor. Another option is to change the
instructions in your ladder logic that monitor for faults if you are using a PLC to monitor the
output.
Motor Connector Wiring Changes
h Interlock Pins:
Not available on the SD8055. Must be connected with a short jumper on the SD17063
for normal operation.
h CTap Pins:
Not available on the SD8055. You do not need to make connections to these pins for nor-
mal operation. These pins are electrically isolated from the drive and are for wiring conve-
nience only. These pins are used with six lead motors and also with eight lead motors
wired in series. Check your wiring diagrams to see if you can use these pins. Wiring dia-
grams for six and eight lead motors can be found in the manual section Step 4: Connect-
ing the Motor on pages 39 and 40.
h ± A Phase:
Can be brought over directly to the SD17063.
h ± B Phase: WIRING MUST BE REVERSED!
The wires in the –B terminal of the SD8055 go to the
+B terminal of the SD17063 and the wires in the +B terminal of the SD8055 go to the –B
terminal of the SD17063.
If the ±B phase wiring is not reversed, the motors rotation will reverse. (Commanding
it to rotate clockwise will rotate it counter-clockwise and a counter-clockwise com-
mand will result in a clockwise rotation. Failure to observe this warning can result in
undesired operation with possible damage to equipment or injury to personnel.
h Earth GND (Shields):
Not used on the SD8055. The shields of the motor cable must be connected to
the terminal for normal operation.
Power Connector Wiring Changes
1) Input power must be 95 to 132 Vac, 50/60 HZ, and able to supply 9.5A
PK
for proper
operation.
2) Never attempt to power the drive with 230Vac. Doing so will damage the drive and
void its warrenty. If you are converting from an SD8055 to the SD17063, verify that
the SD8055 was operating at 120Vac before applying power to the SD17063.
If your
installation only has 230 Vac, you must install a step down transformer to power the
SD17063. The transformer must be rated for a minimum of 1.1KVa.
