1. If you use the double-ended bulkhead in-line connection resolver and feedback cables, do the wall-mount connectors have female pins?
2. When auto-tuning a 1394 SJT Analog servo can you increase the bandwidth so that the gain are tune and it max. bandwidth?
3. How do I find out what products are CE AND UL LISTED?
4. Do you need an external 24 volt power supply and relay for the new 1394C-XX-IH axes module? Can you use the A and B series axes module with the 1394 C system module?
5. What is the difference between the 1394 SJT - A ( Analog) and the 1394 SJT- C / T ( IMC SCLASS/TURBO INTEGRATED MOTION CONTROLLER)?  What is the tech. support handle for either product?
6. How do I interpret the fault code number on the 1394 drive?

Q?  If you use the double-ended bulkhead in-line connection resolver and feedback cables, do the wall-mount connectors have female pins?
A!  The connections on page 7 are set up as follows: The connector on the motor has male pins. The 1326-CCU-D feedback)/CPB1-D/-CPC1-D (power) at the motor end is a double ended female and a double-ended male at the wall mount.  As for the 1326-CCUT-EE(flex feedback) and the CPB1T-EE/ CPC1T-EE (flex power) in the power track. These bulk-headed cables have a double ended female connector that goes to the motor. And the other end is a male double- ended bulk-head that goes to the connection at the axes module. These cable will always have a female connection on the power end. Also the cables have two forms of protection. A female end at the power side and hard fault if the cable is damaged or the connection has been lost.

Q?  When auto-tuning a 1394 SJT Analog servo can you increase the bandwidth so that the gain are tune and it max. bandwidth?
A!  Yes, sometimes when you auto-tune a axis, the gains want be calculated and the maximum band-with. In order to tune the gains to the maximum bandwidth you must you the calculate feature in the ATune Select parameter. After auto-tuning the axis, go to the desire bad-width and set it to 60 hertz or more ( the parameter will scale to the maximum band-with value). Then do a calculate. This will recalculate your gains values to the new bandwidth. No motion is required for this operation.

Q?  How do I find out what products are CE AND UL LISTED?
A!  The CE products we have are located at are Industrial Control and Motion Products page. This is found at www.ab.com, from there select Product Certifications. Click on "VIEW OR PRINT OUR CE DOCUMENTS".  UL listing are typically found in the motion product catalogs.
